Maine woman faces blindness with a sense of determination – Press Herald

Monday, March 6th, 2017

Julie Voisine clutches the red-and-white cane in her hand and listens to the Congress Street traffic whiz past her.

Can you get us back to the car? Mike Dionne asks.

Probably not, Voisine replies.

Break it down, Dionne says. You got it.

Says the man who can see, Voisine says.

She gives him a sarcastic smirk, but she starts to walk.

Now 53, Voisine has been legally blind since age 28. She has retinitis pigmentosa, an inherited eye disease that has slowly claimed her peripheral vision. She also has developed macular degeneration, which is causing her to lose her central vision. Although her sight has always been limited, it has shrunk to a pinprick in recent years.

I have one spot in my vision, Voisine said. Its like taking a straw and putting it up to your eye and looking out of it and crimping the end of it.

In January, Voisine enrolled at the Iris Network Rehabilitation Center in Portland. The 12-week residential program teaches skills she will need to live and work independently when she has entirely lost her vision. Dionne, an orientation and mobility specialist, is one of the instructors who has been working with her for weeks.

Earlier in the week, Voisine slipped on a patch of ice during a solo trip to the post office. Her arm is in a sling during her lesson with Dionne on a sunny Thursday in February, but she sets out with her cane anyway.

Theres too many other things trying to stop me, Voisine said. My vision isnt going to be one of them.

BOOT CAMP FOR THE BLIND

The Maine Institution for the Blind formed in 1905. Its founder was a visually impaired traveling almanac salesman who wanted to help other people with vision loss earn a living wage and learn a trade. The nonprofit has changed its name over the years, but Director of Program Services Rabih Dow said the Iris Network still has the same goal.

People come to us and say, What jobs can blind people do? Dow said. We say, What job would you like to do?

The 2015 National Health Interview Survey estimated that 23.7 million American adults about 10 percent of Americans 18 years and older reported they have some level of vision impairment. That group includes a range, from people who have trouble seeing even while wearing contacts or glasses to those who are completely blind. Most are born with sight and lose it either through disease or trauma, Dow said.

The stereotype of blindness is very stark, he said. It is a relatively uncommon disability, so it can be very isolating.

In 2015, the Iris Network added its first live-in program. Over three months, clients live in a dorm setting in Portlands Parkside neighborhood and study a range of subjects.

Think of it as a boot camp for the blind, Dow said.

Growing up in Penobscot County, Voisine has always known she would lose her vision. Many of her family members her mother, six of her eight siblings, her son also have retinis pigmentosa.

As an adult, she ran several small businesses over the years with her husband. Before he died nine years ago, they had owned a garage, a redemption center and a karaoke service together. But as her vision has worsened, Voisine has not been able to work at all.

Limited public transportation near her home in rural Kingman has frustrated her. She likes to travel, but she relies on her friends to drive her to appointments and the grocery store. She loves to bake, but she began burning or cutting her hands in the kitchen. She missed reading, but she abandoned two attempts to learn Braille.

When a counselor told her about the Iris Network Rehabilitation Center, Voisine signed up immediately.

This program for me is about freedom, she said. Its being free to do the things I want to do.

LEARNING TRICKS OF INDEPENDENCE

Voisine bends over a list of ingredients with her magnifying glass.

In a practice apartment at the Iris Network, clients learn how to cook, do laundry and manage their homes without their vision. So far, Voisine has made red velvet truffles and cheesecake in the test kitchen. Today, she considers two copies of the same recipe for chocolate chip cookies one in large print, one in Braille.

I had to give away a lot of my recipe books before I came here, she said.

With her arm in a sling, Voisine needs some help whisking from Karen McKenna, a certified vision rehabilitation therapist. But she still finds the butter in the refrigerator and preheats the oven. McKenna has labeled many of the spices and measuring cups in the kitchen with Braille.

She and Voisine review the tips she has learned in the kitchen. They place all the necessary ingredients on a tray to keep them organized. Voisine knows to feel the edges of the broken eggshell with a finger to identify the size and shape of any missing chunks. McKenna teaches her students how to identify the sounds and smells that mean food is done cooking.

Hey, Siri, set a timer for nine minutes, Voisine instructs her phone.

The practice apartment is just one of the classrooms that Voisine visits each week.

Elsewhere, she is finally getting the hang of Braille. In the low-vision clinic, clients learn how to maximize the sight they still have. For Voisine, this involves tools like glasses to reduce glare and talking apps on her cellphone. The program puts an emphasis on learning to use the computer to pay bills, file taxes, keep up with an address book and manage other daily tasks. All clients participate in individual and peer counseling. Voisine is making a toy workbench for her grandson in a woodworking class. Her orientation and mobility class takes her outside in all weather to find her way through the grocery store, the public bus system and the streets of Portland.

I am not my cane, Voisine said. I am just somebody trying to live my life.

The smell of warm cookies fills the kitchen. Voisine sniffs the air.

The cookies are almost done, she says.

She opens the oven just as the timer buzzes.

FROM CAUTIOUS TO CONFIDENT

When Voisine graduates from the Iris Network program, she hopes to find work in Portland.

She has joined the YMCA and applied for an apartment. She often helps the staff at the nursing home where her mother lives, so she has decided to become a certified nursing assistant. She would also like to find a part-time job at a bakery.

She will take the bus from Portland to New York City to visit her son this spring, and she wants to travel to England and Ireland next year.

Ive had people say to me, Id rather be dead than blind, she said. Im like, Im sorry your life is so small.

When she first started to walk the streets of Portland with Dionne, Voisine was cautious and slow. She often wears a blindfold during these lessons to prepare for her total vision loss, and the traffic in Portland is busier than her hometown. But her confidence has grown with every lesson.

Shes embraced it, Dionne said. She goes out and does the things she wants.

During their recent lesson, she walks Congress Street in the afternoon sun. Dionne follows a few paces behind, ready to intervene when she gets turned around in a parking lot. He tells her to listen to the traffic and guess the configurations of the intersections they pass.

Its a two-way, she says confidently at the intersection of Pearl and Congress streets. Its a light.

Voisine pauses at the intersection of Congress and Exchange streets. This is the final crosswalk of her lesson. The car is just a block away.

After we cross here, youre going to turn left, Dionne said.

Voisine nods her head vigorously.

She starts to step into the street, but immediately jumps back onto the curb as she hears a car approach. The white PT Cruiser makes the turn onto Exchange Street.

A group of teenage girls with Urban Outfitter shopping bags chatter to each other as they cross the street. Voisine reaches a foot onto the asphalt, then pulls it back. She tilts her head and listens to the sounds of passing cars. And then, Voisine quickly steps into the road and strides across. She cant see the white lines of the crosswalk, but she follows them perfectly. She sweeps her cane in a wide arc in her path, and Dionne hurries behind her to keep up with her quick steps.

Her cane taps the opposite curb, and she turns left.

Blissful color-blindness of the young children … – Enid News & Eagle

Sunday, March 5th, 2017

Recently the mother of a 5-year-old boy in Louisville, Ky., told her young son he needed a haircut.

He asked if he could get the same haircut as his best friend, because Were going to trick the teacher.

The boy thought if he had the same haircut as his buddy, their pre-K teacher couldnt tell them apart.

Jax, the boy needing the haircut, wanted to get a buzz cut like his friend, Reddy, who is also 5. So he did.

The punchline of this endearing story is that Jax is white, Reddy is black. The difference in their pigment, apparently, never crossed the boys minds when they plotted to fool their teacher.

Would that we all could be that way, seeing each other as friends and fellow human beings rather than as black, white, yellow, red, brown, green, purple or any shade.

Children see only another person whom they like and want to play with, not a person of another race. Prejudice, it seems, comes only with age and experience.

In the classic Rogers and Hammerstein musical South Pacific, there is a song in the second act that highlights this phenomenon.

Young Navy Lt. Cable has fallen in love with a Polynesian girl, Liat, but he knows he cannot marry her because of his familys prejudice.

At the same time, Ensign Nelly Forbush decides she can no longer love French plantation owner Emile because of his two half Polynesian children.

It is a short song with a powerful message, Youve got to be taught to hate and fear.Youve got to be taught from year to year. Its got to be drummed in your dear little ear. Youve got to be carefully taught.Youve got to be taught to be afraid, of people whose eyes are oddly made, and people whose skin is a diffrent shade.Youve got to be carefully taught.Youve got to be taught before its too late, before you are 6 or 7 or 8, to hate all the people your relatives hate, youve got to be carefully taught!

Over the years too many have learned those lessons too well.

In an article published in the St. Louis American, an African-American newspaper in that Missouri city, Roland Bob Harris, a St. Louis native, writes about his time in the Air Force, including his tenure serving at Vance Air Force Base in the late 1950s.

Segregation reigned supreme, Harris wrote. The blacks in Enid literally lived on the other side of the tracks. There were only two black policemen. They could only patrol in the black section of Enid. Enid was a very dismal assignment.

Thank God we have come a long way since the late 1950s, though we still have far to go.

For young airmen assigned to Vance today, this still may be a dismal assignment, but only because of Enids small size and long distance from a major metropolitan area, not because of rampant racism.

We could learn a lot from Jax and Reddy. Color shouldnt matter, period. Of course, neither should your country of origin, how you choose to worship nor who you decide to love.

Why must we be so quick to hate, so eager to distrust, so reluctant to love, so hesitant to accept?

We have, I fear, been carefully taught.

We can only pray thats a lesson Jax and Reddy never learn.

Student hopes to cure mpother

Jonathan Munson and Madeleine Dart, KIII 4:51 PM. PST March 03, 2017

CORPUS CHRISTI (KIII NEWS) - Del Mar College student Jessica Lybarger, a mechanical engineering major, said she is pursuing a degree in biomedical engineering so that someday she can build her mother a pair of robotic eyes.

Lybarger's mother was diagnosed seven years ago with diabetic retinopathy. The condition led to her mother going blind in both eyes, despite more than 100 surgeries.

In a post by Del Mar College, Jessica said, "I just want her to enjoy all the memories with us as a family. My mom has missed out on seeing my brother get married, and soon I will get married too. I hope that with the success of my robotics, I can help change the lives of others who suffer from the same condition as her."

See the post below:

Kiii News Reporter Madeleine Dart spoke with Lynbarger Friday and came back with her story.

Philanthropy vs. Blindness: What’s the Latest? – Inside Philanthropy

Saturday, March 4th, 2017

If ever there were a problem that might seem tailor-made for philanthropy, it's fighting blindness. Losing sight is a horrifying fate for anyone to contemplate, and it's not surprising that blindness has motivated some deep-pocketed donors for at least a century. Over the past few decades, significant gains have been made in this area. In the United States, for example, the Foundation Fighting Blindnessco-founded by venture capitalist George Gund in 1971has raised over $600 million to fund research advances to prevent and cure retinal degenerative diseases that affect more than 10 million Americans. Worldwide, a range of efforts have sought to bring poor countries affordable cataract surgery. Cataracts are the main cause of blindness for half of the 40 million or so people who cannot see. Millions of people can see today because of these efforts.

This fight would seem eminently winnable, given that the World Health Organization estimates that 80 percent of blindness is avoidable, meaning it can be either prevented or reversed. Spurred on by that hopeful fact, the WHO galvanized a plan in 1999 called Vision 2020,a global initiative to prevent avoidable blindness, with a coalition that includes a number of foundations and top nonprofits.That milestone is now just three years away, and much work remains.

As usual, one key obstacle to faster progress has been funding. Never mind that the world's 2,500 billionaires now have assets of around $7.6 trillionthere's just never enough private or public money to fight blindness. Today's wealthy spend a fortune on luxuries even as millions of their fellow human beings cannot see. As a practical matter, reducing blindness has to compete with a bunch of other global health priorities, starting with diseases that actually kill people, like malaria and HIV/AIDS.

In addition, there aren't nearly as many major funders focused on preventing blindness as you might think. Very few of the largest U.S. foundations have made this a priority.

The Gates Foundation has patched in and out of this issue over the past 18 years, spending tens of millions fighting neglected tropical diseases that cause blindness, including large grants in the past to the Carter Center, the Task Force for Global Health, and Johns Hopkins University. But blindness hasn't been a big priority lately, at least compared to the foundation's investments in other areas.

Recently, the MacArthur Foundation announced that two of its eight semi-finalists for a special $100 million grant were organizations fighting blindness: Himalayan Cataract and the Carter Center. The fact these two made it into the top tier out of 2,000 proposals underscores the potential for big new money to make a huge impact (which is the goal of Mac's 100&Change competition).

While MacArthur's entry into the blindness space could be a game-changer, the Conrad N. Hilton Foundation stands out as one of the steadier big funders here. In particular, it's worked tirelessly to eliminate trachoma, a major cause of blindness. Trachoma is a result of repeated chlamydia trachomatis infections in the eyes. The infection, which typically starts in infancy or childhood, causes the eyelid to turn inward, resulting in corneal scarring caused by the eyelashes rubbing on the eyeball. Trachoma is incredibly painful, and if left untreated, leads to irreversible blindness. The debilitating disease is endemic in some of the poorest countries in the world.

Hilton uses the World Health Organizations (WHO) SAFE strategy (surgery, antibiotics, facial cleanliness, and environmental improvement) approach to eliminating blinding trachoma in Mali, Niger, and Tanzania. The foundation has played a crucial role in eliminating the disease in Ghana, which achieved its elimination targets in 2014. While this is a major success, Hilton isnt celebrating just yet. The foundation still has blinding trachoma in its sights and just awarded millions in grants to eliminate the disease.

Related: Researching Blindness Treatments? Conrad N. Hilton Foundation is on Your Side

Hilton made a total of $11.725 million in grants to three organizations that know more than a little bit about trachoma and avoidable blindness.

At just under $6 million, Helen Keller International received the largest award in this round. Established over 100 years ago, Helen Keller International has been on the front lines of the global trachoma battle since the 1950s, and has over 120 programs across Africa and Asia. Using the WHO's SAFE strategy as well, Helen Keller administered more than 80.5 million integrated neglected tropical disease (NTD) treatments in six African countries in 2016.

Coming in a close second behind Helen Keller International, the Carter Center received a $5.1 million grant from Hilton. The Carter Center has been a leader for over 30 years in the war against NTDs such as guinea worm, river blindness and trachoma. Since 1999, Carter has implemented the SAFE strategy in Mali and Niger. The Carter Center has facilitated thousands of surgeries and administered more than 500 million doses of antibiotics through its mass drug administration programs. Carter has also backed the construction of nearly 220,000 latrines in Mali and Niger. Better water, sanitation, and hygiene plays a critical role in preventing the spread of trachoma.

The final grant in this round was awarded to Sightsavers, which received $650,000. Sightsavers is a U.K.-based organization that has been working to eliminate avoidable blindness for six decades in over 30 countries around the world. Over the years, the group has supported more than 575 million treatments for blinding and potentially blinding conditions, and backed over 8 million surgeries to restore sight. Caroline Harper, CEO of Sightsavers, called Hiltons donation vital to meeting the WHO target for eliminating blinding trachoma by 2020.

Helen Keller International and the Carter Center are using the Hilton grants for trachoma prevention and elimination programs in Mali and Niger. Sightsavers is using its donation from Hilton to back its work in Mali. Both countries are within reach of their trachoma elimination targets.

Related: Where Have Hiltons Global Grants Been Going Lately?

The Hilton Foundations $11.725 million in grants certainly provides a nice boost toward eliminating trachoma in Mali and Niger, and the leveraging power of those funds could help both countries reach the elimination finish line. Hiltons latest trachoma grants require a dollar-for-dollar match by 2020 from each organization. Meaning, the foundation is effectively mounting a three-year, $23.45 million trachoma eradication campaign.

Indictment: VA sees through veteran’s claim of blindness after catching him driving to the hospital – Hutchinson News

Saturday, March 4th, 2017

An Army veteran from Reno County has been indicted on federal charges of collecting $63,000 in benefits by pretending to be blind, U.S. attorney Tom Beall announced Thursday.

Billy J. Alumbaugh, 61, and his ex-wife, Debra K. Alumbaugh, both of Turon, each are charged with one count of conspiracy to defraud the government and one count of theft of government funds, according to a news release from the U.S. attorneys office in Wichita.

An indictment unsealed Thursday accuses Alumnbaugh of fraudulently receiving a supplemental monthly pension by claiming he was legally blind and needed assistance to perform routine activities.

Alumnbaugh claimed he was unable to drive and needed assistance with reading medication labels, buying groceries and going to medical appointments, the news release said. The indictment charges him with making periodic trips to the Veterans Administration hospital in Wichita, where specialists couldnt find medical reasons for his blindness.

From 2009 to 2016, while he was receiving assistance, he maintained a Kansas drivers license that did not require corrective lenses and routinely drove his car. In October 2016, he and his ex-wife arrived at the VA hospital, with his ex-wife driving. She also drove when the appointment was over, but they stopped the car after driving a few blocks and switched seats so he could drive, the news release said.

If convicted, the conspiracy charge carries a sentence of up to five years in federal prison and a fine of up to $250,000. The theft charge carries a maximum sentence of 10 years and $250,000.

The Veterans Administration Office of Inspector General investigated the case. Assistant U.S. Attorney Brent Anderson will prosecute the case.

Swansea boy with color blindness hoping for return of special glasses – Fall River Herald News

Saturday, March 4th, 2017

Deborah Allard Herald News Staff Reporter @debsallard

SWANSEA Kids lose their glasses. It happens.

But, when Connor Latessa lost his glasses a few weeks ago, the color went out of his life.

Connor, 13, is color blind. Most of what he sees appears in shades of brown.

But, Connors special glasses allowed him to see a full rainbow of colors until he lost those glasses at school or on the way home from school.

They made everything more colorful and vibrant, Connor said.

Rachel Latessa, Connors mom, said she surprised him with the $600 glasses hed been wanting for months. It was during a Christmas party with the family all there to see Connor try out his new glasses, while they held up colorful balloons.

Connor cried when he got his first look at all the reds and greens hed been missing, and especially when he saw the Christmas lights outside.

When I got them I was very emotional, Connor said. I really didnt know what I was seeing.

He said greens and browns are mixed up to him. And, he has a hard time distinguishing between blues and purples. Orange appears as green, and light blue as pink.

We found out when I was really little, Connor said.

Latessa said she noticed things she found odd when he was young, like calling his light blue blanket pink, and crying when he was given green lollipops, though they were really orange.

Different colors, he would call something else, and hes really smart, Latessa said.

When Connor was 5, she had him examined and found out for sure he was color blind. I wasnt surprised, Latessa said.

Its an affliction carried by the women in Latessas family and passed only to male children. Im a carrier, she said.

Her father saw only in black and white, and got in trouble when he was in school for coloring everything black the most vibrant color to him in the crayon box.

Connor understands everything about the condition, and even made it his science project at Joseph Case Junior High School, where he is a student.

Its because of the X and Y chromosome, Connor said, going on to explain the scientific intricacies. He said it affects one in 10 men and one in 200 women. Hes right, according to several websites.

Latessa said Connor being color blind is just something theyve learned to live with, though the glasses are a big help, especially outside where they work best.

It doesnt affect us too much, Latessa said. At times, Ill see something very colorful, and it makes me sad. I wish he could see it.

When a friend of the Latessa family learned that Connor had lost his beloved glasses, she started an online fundraising campaign and collected $500 in just a few hours.

Latessa said shes still hoping someone finds the glasses before buying a new pair.

The glasses look just like sunglasses and are EnChroma brand, which blends a marriage of color vision science and optical technology, according to its website.

If anyone locates the special glasses, contact Latessa at rmlatessa@aol.com or drop them at the office of Joseph Case Junior High School.

Association’s Name Change Focuses on Sight, Not Blindness – Associations Now

Friday, March 3rd, 2017

The New Hampshire Association for the Blind doesnt want to limit its mission because of its name.

As a result, this week the 105-year-old organization announced that it is changing its name to Future in Sight, which the group says better reflects its goal and overall duties within the state.

In an interview with New Hampshire Public Radio, Future in Sight President and CEO David Morgan noted that 93 percent of the people the organization serves have some form of sight loss but arent blind.

From the interview:

Up until recently, we never served babies. We served seniors, but not outside their home. And more and more, were discovering there are some 30,000 New Hampshire residents with profound sight loss, and we only served about 1,100 last year. So theres certainly a compelling need out there thats left unfulfilled. And frankly, the word blind in our name inhibited a lot of conversations, particularly in doctors offices and between doctors and their patients.

The latter situation proved a significant problem for the organization, according to Morgan, who told the Concord Monitor that the group had expanded its mission in recent years, partly because of changes with the states offerings. As a result, the association has received more referrals from doctors.

But these referrals created problems because members of the public were thrown off by the name.

The new name already has had an important impact on these conversations, Morgan stated.

As we stopped using the word blind, what we did was create new conversation around the word sight and the use of whats left for residual sight for both school-age kids and adults, he explained in his New Hampshire Public Radio interview.

In a blog post, Morgan added that the group is also expanding its mission to bordering states around New Hampshire.

Run color blindness tests on your websites – gHacks Tech News – Ghacks Technology News

Friday, March 3rd, 2017

Color blindness affects a large percentage of the population. Studies have shown that up to 8% of males and 0.5% of females of Northern European heritage are affected by red-green color blindness for instance. The ability to distinguish between colors gets worse with age as well.

As a webmaster, you may want to make sure that your site is accessible to visitors with color blindness, or difficulties distinguishing certain color patterns.

This gives those users a better experience on your site, and may prevent part of them from insta-closing the site when they run into accessibility issues.

Probably the best way of checking your websites quickly when it comes to accessibility for color blind visitors is to use a browser extension. Some sites and services may require more than that, but the extensions should be fine for the majority of webmasters out there.

RGBlind is a simple extension. It adds an icon to the main Firefox (or Chrome) toolbar on installation that you can click on to switch between two color blindness simulation modes.

You may switch to test Protanopia or Deuteranopia, and will notice that the color scheme of the site you are on changes immediately once you make a selection. The difference between the two forms is that in protanopia, the red retinal photoreceptors are missing, whereas in deuteranopia, it is the green photoreceptors that are missing.

Basically, what the test does is simulate color blindness, so that you can see how a color blind person would see the website.

Dalton for Chrome adds tests for eight different types of color blindness to the browser. Simple navigate to the website that you want to check for accesibility, click on the extension icon, and select one of the available types (Achromatomaly, Achromatopsia, Tritanomaly, Tritanopia, Deuteranomaly, Deuteranopia, Protanomaly, Protanopia)

The extension pains the colors of the site accordingly, so that you can verify what works, and what does not.

You need to click on each type separately to test them all. An option to rotate through all types automatically would be useful, but is not provided.

Another browser extension for Google Chrome that you may use to test a site#s accessibility for the color blind.

It works almost identical to Dalton above: click on the icon, select one of the available types, and watch as the site's color scheme gets modified accordingly by the extension. Supports the same eight types as Dalton.

Colorblind test extensions for Firefox and Chrome are helpful to webmasters and designers, as it allows them to test a site's or design's accessibility. The extensions are easy to use, and it should not take longer than a couple of minutes to run initial tests to find out how well, or not, the site displays for visitors affected by the various types of color blindness.

Now You: are you color blind? Are there many sites out there that don't show up correctly for you?

Using the WHO's SAFE strategy as well, Helen Keller administered more than 80.5 million integrated neglected tropical disease (NTD) treatments in six African countries in 2016.

Coming in a close second behind Helen Keller International, the Carter Center received a $5.1 million grant from Hilton. The Carter Center has been a leader for over 30 years in the war against NTDs such as guinea worm, river blindness and trachoma. Since 1999, Carter has implemented the SAFE strategy in Mali and Niger. The Carter Center has facilitated thousands of surgeries and administered more than 500 million doses of antibiotics through its mass drug administration programs. Carter has also backed the construction of nearly 220,000 latrines in Mali and Niger. Better water, sanitation, and hygiene plays a critical role in preventing the spread of trachoma.

The final grant in this round was awarded to Sightsavers, which received $650,000. Sightsavers is a U.K.-based organization that has been working to eliminate avoidable blindness for six decades in over 30 countries around the world. Over the years, the group has supported more than 575 million treatments for blinding and potentially blinding conditions, and backed over 8 million surgeries to restore sight. Caroline Harper, CEO of Sightsavers, called Hiltons donation vital to meeting the WHO target for eliminating blinding trachoma by 2020.

Helen Keller International and the Carter Center are using the Hilton grants for trachoma prevention and elimination programs in Mali and Niger. Sightsavers is using its donation from Hilton to back its work in Mali. Both countries are within reach of their trachoma elimination targets.

Related: Where Have Hiltons Global Grants Been Going Lately?

The Hilton Foundations $11.725 million in grants certainly provides a nice boost toward eliminating trachoma in Mali and Niger, and the leveraging power of those funds could help both countries reach the elimination finish line. Hiltons latest trachoma grants require a dollar-for-dollar match by 2020 from each organization. Meaning, the foundation is effectively mounting a three-year, $23.45 million trachoma eradication campaign.

New Retinal Device May Give Hope To The Blind – CBS Chicago

Thursday, March 2nd, 2017

March 1, 2017 10:08 PM By Marissa Bailey

(CBS) A blind man can see light for the first time in 20 years, all thanks to a revolutionary device being researched right here at the University of Illinois-Chicago.

CBS 2s Marissa Bailey explains how it could change the lives of the blind.

This is no regular eye doctors appointment.

This is Bob Selbys first check-up since Dr. Jennifer Lim at UIC implanted the groundbreaking retinal device called the Argus II.

Ive been legally blind my whole life, really, Selby says.

The 55-year-old was born with Retinitis Pigmentosa. He was diagnosed in his 20s and completely blind by 35.

The part of the retina that doesnt work is the part of the retina that gathers the light. The photoreceptors are dead but the inner retina works, Dr. Lim explains.

Selbys device was implanted in October and thenturned on in November. Thats when he saw light flashes for the first time in more than 20 years.

Now he can see edge and contrast effects and can pick people out, but before he didnt know where they were unless they would say something, Lim says.

Heres how the device works: The lens on Selbys glasses transmits an image through a video processor box. It wirelessly sends instructions to the implant on Selbys eye. Those messages stimulate Selbys retina to send signals along the optic nerve to his brain, which allows him to see.

Within minutes of turning on the device, Selby was navigating unfamiliar hallways by himself.

Wow! Ive never been so happy to see a wall before, he said that day.

Selby calls the technology a game-changer.

For patients, its huge.To be able to see light and then not only to see the light but to have the light mean something, Lim adds.

Selby practices with his new found sight a couple of hours a day.

He says if he can see light flashes now, this may be the beginning of the end for blindness.

Imagine what they could do in five to 10 years, he says.

Selby is one of only 60 people in the world with this FDA-approved retinal implant. UIC is one of 13 sites in the U.S. where its being used.

The Argus II is now being studied in Europe for people with macular degeneration.

Marissa Bailey is the weekend anchor of the CBS 2 Chicago morning newscasts and a general assignment reporter for the station. Marissa joined the station in March 2012 as a reporter and was promoted to anchor the stations Saturday and Sunday...

Beware Of This ‘Thief Of Sight’ That Can Gradually Cause Blindness – malaysiandigest.com

Thursday, March 2nd, 2017

Details Published on Thursday, 02 March 2017 08:32 Written by Thorsten Marquardt

Glaucoma, the silent thief of sight, is a group of diseases caused by damage to the optic nerve in the eye.

Without any warning signs or symptoms it will slowly take away the affected persons eye sight and can even cause blindness if not treated appropriately.

Tanaletchimy Rajaratnam, 63, felt completely healthy and had no symptoms at the time she was diagnosed with high eye pressure during a routine eye screening in the UK.

With high eye pressure being the number one cause for glaucoma, she decided to start the treatment right away.

Taking the risk seriously, going for regular checkups and starting with the treatment early enough helped keeping the diseases progress at bay.

This is the reason why today, 10 years after she was diagnosed with glaucoma, her eye sight has not been significantly affected.

Without early detection and swift action, this could have played out very differently.

Another patients son, Mr Wong, told MalaysianDigest, at the Tun Hussein Onn National Eye Hospital that his 75 year old father had been affected by glaucoma for a long time without even noticing it.

Only after the disease had already severely damaged his eyes and even started to cause pain, he finally consulted a doctor.

Without appropriate treatment, he is now at risk of going blind.

Before being diagnosed with the disease, like most people, both patients werent even aware of its existence. Like many other glaucoma patients in Malaysia, Wong andTanaletchimy accounts of the onset of the disease highlights the invisible nature of this condition until it is too late.

The Malaysia Glaucoma Society had produced the following public announcement about this disease a few years back to create awareness of this 'silent thief of sight'.

The World Glaucoma Week held in March each year takes place on 12 to 18 March 2017 and to help raise awareness, we have decided to highlight this often 'invisible' illness and look at a local eye hospital's role in helping glaucoma patients.

The Silent Thief Of Sight

If the optic nerve that connects the eye to the brain is too damaged, it will not be able to send an accurate and complete picture to the brain causing reduced eye sight.

This results in people having blurry vision and a restricted field of view or missing objects in their view.

Glaucoma usually comes without any symptoms and often stays undetected for a long time.

Not always, but very often, glaucoma is caused by high eye pressure damaging the optic nerves.

To be more specific, glaucoma usually develops when the production of an eye fluid called aqueous humour either increases or fails to drain properly.

This causes the pressure in the eye to rise which can damage the fibres in the optic nerve resulting in interruptions to the transmission of visual messages to the brain.

Eye drops are used to reduce the eye pressure and keep it stable to prevent further damage to the nerves.

Eye pressure is the main cause for glaucoma, but not required for its development.

People with normal eye pressure can still be affected, while people with high eye pressure are more likely to be at risk but dont necessarily develop the disease.

It is estimated that half of the people affected by glaucoma do not know that they have it, which is a serious problem because if left undetected and untreated it can lead to blindness.

According to the World Health Organization, Glaucoma is the second most common cause of blindness worldwide and it is estimated that 4.5 million persons globally are blind due to glaucoma.

If left untreated, most types of glaucoma progress (without warning nor obvious symptoms to the patient) towards gradually worsening visual damage and may lead to blindness, states the World Glaucoma Association.

Since there is no cure, the damage caused to the optic nerves and the reduced eye sight are irreversible, therefore it is important to detect it early.

There is no cure for glaucoma as yet, and vision loss is irreversible. However medication or surgery (conventional or laser) can halt or slow-down any further vision loss. Therefore, early detection is essential to limiting visual impairment and preventing the progression towards severe visual handicap or blindness, states the World Glaucoma Association.

Everybody Is At Risk Of Glaucoma

Datuk Dr. Linda Teoh, a full time consultant ophthalmologist and glaucoma specialist at the Tun Hussein Onn National Eye Hospital (THONEH), told MalaysianDigest that everybody can be affected by glaucoma.

There are certain risk factors, like for example high eye pressure and a family history, but the disease can affect anyone.

It is not just about the eye pressure. The eye pressure might be normal but the person can still develop glaucoma. There can also be people with high eye pressure but no glaucoma. Too many people look only at the eye pressure, she said.

People with high eye pressure are at a much higher risk of getting glaucoma and it is generally assumed that people with a family history of glaucoma already have a 1 in 4 chance of developing the disease.

There are, however, many other factors that come into play.

Everybody is potentially at risk of developing glaucoma, but there are certain risk factors that increase the likelihood.

People above the age of 60, people with diabetes, people who have used steroids for a long period of time and people with physical eye injuries are also at a higher risk.

Some ethnicities are more prone to the disease than others.

The Glaucoma Research Foundation found that African Americans are more likely to be affected by glaucoma than Caucasians.

The ingredients of certain weight loss appetite suppressant pills are also linked to an increased risk.

In Malaysia around 1.8 percent of the population is affected by glaucoma and, according to surveys, only 21 percent of the population are even aware of the disease.

Since glaucoma is very unpredictable, can affect anyone and comes without warning, routine eye checkups, measuring eye pressure and conducting visual field tests are crucial in detecting and treating the disease early enough to avoid major irreversible damage to the eye sight.

Education And Cooperation Between Doctor And Patient Are The Key To A Successful Treatment

When it comes to treating glaucoma, it is very important that the patient and the doctor are on the same page.

Since glaucoma is a disease that continuously gets worse while causing irreversible damage, regular checkups and adjustments to the treatment are very important.

In order to keep the disease from progressing, it is required to keep the eye pressure low and stable.

Datuk Dr. Linda Teoh, a full time consultant ophthalmologist and glaucoma specialist at the Tun Hussein Onn National Eye Hospital (THONEH)Glaucoma is actually a group of diseases causing damage to the optic nerve of the eye. By controlling the eye pressure, the drops can slow down the progress of glaucoma, Dr. Linda explained.

I think what is important is education. Patients should know the nature of the disease and understand how it progresses.

Despite the aggressive nature of the disease and lack of cure, it is possible to prevent the loss of eye sight through appropriate treatment.

This, however, can be costly, time consuming and requires the patients to actively take an interest in informing themselves about the disease and be compliant with their medication.

Dr. Linda thinks that a lack of education and knowledge about the disease leads many patients to be neglectful and hamper the effectiveness of the treatment.

They feel there is no improvement in spike of treatment. They fail to understand the nature of the disease. Then they blame the doctor if they dont get better. They always want to improve, but what they dont understand is that Glaucoma cannot be improved; its progress can only be slowed down. What they need is education, she said.

In order to successfully treat the disease and prevent it from progressing, patients have to go for regular checkups, use the prescribed medicine correctly, meet doctors regularly to adjust the treatment based on changing conditions and undergo surgery (to control the eye pressure) if the necessity arises.

The drops used to reduce the eye pressure, for example, have to be adjusted regularly depending on whether the eye pressure are effectively controlled in order to avoid fluctuations that damage the optic nerve further.

Dr. Linda opined that patients who are either too uninformed and ignorant about the disease or dont trust the doctors are more likely to fail at properly treating the disease.

Tanaletchimy, who managed to slow down the progress of the disease by being very proactive and engaged with her doctors also sees cooperation between doctors and patients as the most important factor.

Just listen to what the specialists have to say. They are the experts. You must have confidence in the doctor and just follow what the doctor suggests, she said.

According to Dr. Linda, education, cooperation with the doctor, early detection and early treatment are the most important factors in successfully treating glaucoma.

In conjunction with the World Glaucoma Week 2017 starting from March 12, the Tun Hussein Onn National Eye Hospital (THONEH) will be hosting an open day on 22 March 2017 (Wednesday).

There will also be a presentation ceremony and a series of programmes including an eye health talk open to the public. For further information, contact THONEH at 603-7718 1588 or email This email address is being protected from spambots. You need JavaScript enabled to view it..

‘Treasure map’ identifies first genetic clues to form of blindness – Blue Mountains Gazette

Thursday, March 2nd, 2017

27 Feb 2017, 6:11 p.m.

Researchers have identified genetic clues which could reveal a person's risk of going blind.

Tom Doumani thought something was up when he started having trouble reading street signs while driving. Letters seemed to be missing and, if the street name was an unfamiliar one, he had no way of guessing what it might be.

It was enough to prompt him to go and get his eyes tested. However the results showed his long distance vision was fine.

Unconvinced all was as it should be, he mentioned it to his GP who referred him to an eye specialist. This time the tests picked it up. Dr Doumani had the rare and rather awkwardly named Macular Telangiectasia type 2.

Like many rare conditions, little is known about what causes "MacTel 2", which in scientific circles is known as idiopathic juxtafoveal telangiectasia. Idiopathic meaning "of unknown cause".

However that may have changed, thanks to research led by Melbourne scientists which has found "a treasure map" revealing the location of the genetic triggers behind this little-understood form of blindness.

Outlined in the journal Nature Genetics, it is the first clue as to what causes MacTel 2, an incurable and untreatable degenerative disease which affects people from age 40 upwards.

The condition is characterised by an abnormal growth of blood vessels in the macula. Patients lose their central vision and tasks such as driving and reading can become impossible.

The international study was led by Walter and Eliza Hall Institute of Medical Research scientists Melanie Bahlo and Thomas Scerri.

The research team, including scientists in New York and London, analysed more than 6 million genetic markers in the genome of patients with the condition and compared them to those without.

Among the 476 people diagnosed with MacTel 2, genetic similarities were found in five key regions of the genome.

Curiously four of the five regions are associated with a person's metabolism. Those with MacTel 2 recorded lower levels of the basic amino acids glycine and serine.

"That was a bit of a surprise to say the least," Professor Bahlo said.

The fifth region identified, in what Professor Bahlo has described as "our treasure map", is tied to the size of retinal blood vessels.

"This is the first time we have been able to say with certainty that this is a genetic condition," she said. "And the map tells us where to 'keep digging' in order to discover the specific genes implicated in MacTel 2."

Identifying the specific genes would lead to improved diagnostic testing for the disease which is notoriously difficult to identify and also developing ways to prevent or stop its progression.

Diagnosed in 2012 at the age of 61, retired corporate banker Tom Doumaniwas among theMelbourne participants, sourced through Centre for Eye Research Australia. Heknows that while he may not benefit directly from participating in the study, he is contributing to the global search for a cause or cure.

"To help advance the knowledge, that's what appealed to me in taking part," he said. "I had no hesitation in participating."

Wayne State University scientists discover the Zika virus can … – Fox17 – Fox17

Wednesday, March 1st, 2017

DETROIT Scientists with Wayne State University say they are the first to publish research to show the Zika virus can damage retina cells in the eyes, and in some cases cause blindness.

The key message of the study is that indeed the Zika virus can cause damage, said Dr. Ashok Kumar, microbiologist and assistant ophthalmology professor with Wayne State University School of Medicine at the Kresge Eye Institute.

Dr. Kumar led a team which launched research in July to publish their study in JCI Insight, the Journal of Clinical Investigation Feb. 23.

Using mice Dr. Kumar says the Zika virus can infect and cause lesions in retina cells, causing damage and in some cases cause blindness. Their research showed the Zika virus mostly killed cells specifically lining the blood-retinal barrier, the retinal endothelium, and retinal pigment epithelium.

Zika virus can actually infect those cells, and we did studies and we found it can replicate in those cell types and ultimately it kills those cells, said Dr. Kumar.

Their study builds on existing research published May 2016 in the Journal of the American Medical Association Ophthalmology that linked the Zika virus to eye problems. Researchers showed that some infants born with congenital Zika infection and microcephaly-or significantly smaller head and underdeveloped brain-in the northeast state of Brazil, Bahia, they also had problems in their retinas, other organs, and some hearing loss.

Pretty much the whole eye can be infected with the Zika virus, said Dr. Gary Abrams, ophthalmology professor with Wayne State University School of Medicine at the Kresge Eye Institute, who assisted Dr. Kumar with the clinical aspect of this study.

Dr. Abrams says about one third of infants born with Zika will develop eye issues they have discovered, whereas 15 percent of adults with Zika will have some sort of ocular impact, but most do not get a retinal infection.

This is a virus thats fairly pervasive: once the infection occurs it can be pretty much all over the body, including in the eyes, in the tears, and elsewhere, said Dr. Abrams.

Currently, Dr. Kumar says they are continuing research in hopes of developing methods to track and treat Zika infections. According to the Centers for Disease Control and Prevention, there is no known treatment at this time.

There are so many questions we dont know, said Dr. Kumar. First thing is: how does the virus replicate? How long is it going to replicate? And what will be the visual outcome.

The big question really is that Zika virus was discovered in 1947, so its about 70 years, and why suddenly is it becoming so prevalent?

Did you know diabetes can cause blindness? – Londoner

Wednesday, March 1st, 2017

Diabetics who may be experiencing vision loss without realizing it are the target of a new awareness campaign St. Josephs Health Care London hopes will lead to more screening.

Vision loss can be sneaky, said London-based optometrist, Harry Van Ymeren, in a news release. In my practice, I have seen it many times. People think they are fine and we discover a problem. The point of screening is to catch it before it becomes too late.

Diabetes is a chronic disease that prevents the body form making or using insulin, in turn increasing sugar levels in the blood stream. The development of early-onset cataracts and glaucoma is more likely for people who have diabetes, but Tom Sheidow, an ophthalmologist at the Ivey Eye Institute, said the main threat is the effect of diabetes on the retina, the part of the eye that allows you to see.

This is why screening early and often is so important for those with diabetes, he said. Diabetes can affect all blood vessels in your body, including those inside your eye. Diabetic eye damage, also called diabetic retinopathy, occurs when there is a weakening of the blood vessels in the retina that can result in swelling, the abnormal growth of blood vessels, and potentially severe bleeding. If diabetic retinopathy is left untreated, blindness can result.

According to St. Joes, estimates put the number of people in Canada with some form of diabetic retinopathy at around two million. It is the most common cause of blindness in people under age 65 and the most common cause of new blindness in North America.

Sarah MacArthur was diagnosed with type 1 diabetes at the age of three and has been cautious with her care because she understands the importance of screening. MacArthur said she has discovered symptoms of diabetic retinopathy in the past four years because of screenings with Van Ymeren.

I had no signs at all, she said. There was nothing that prompted me or made me think something was wrong with my vision. We are keeping a close eye on any changes so we know immediately if there is a concern.

A routine eye examination is all it takes to diagnose potentially threatening changes that can cause blindness. But once damage has occurred, the effects can be permanent.

People who feel completely healthy are the focus of this diabetes vision screening awareness campaign, said Sheidow. Anyone with diabetes (both type 1 and type 2) should have their vision checked.

Referrals to an optometrist from a family doctor are not required and in Ontario, the cost of an eye exam for people living with diabetes is covered through OHIP. Resources to locate an optometrist are available at opto.ca. For communities without an optometrist, an ophthalmologist is an option, said Van Ymeren.

It doesnt matter if you see an ophthalmologist or an optometrist, as long as you get your eyes checked. Yearly screening is free for people with diabetes.

Genetic clue to form of blindness could lead to early diagnosis – ABC Online

Tuesday, February 28th, 2017

Posted February 28, 2017 17:44:11

The first genetic indicator of an eye disease which results in blindness has been discovered by an international team of researchers.

The degenerative eye disease Macular Telangiectasia type 2, or MacTel, is incurable and usually strikes people who are over the age of 40.

Up until now identifying a possible cause for the disease has been difficult.

Scientists are unsure as to how many Australians have MacTel, but they estimate somewhere between 500 and 1,200.

The disease affects the macular the centre of the eye said Professor Melanie Bahlo, from the Walter and Eliza Hall Institute in Melbourne.

"What happens is blood vessels dissolve and start growing into the centre of the eye, and that leads to blindness," she said.

"And there's also the crystalline deposits that form."

This leads to a gradual loss of central vision over a period of 10 to 20 years, impacting people's use of their sharp vision for tasks like driving and reading.

There were also signs that there could be genetic predispositions for MacTel in certain people.

"You can get several family members [with the disease], in the worst case scenario," Professor Bahlo said.

"That usually means that there's a genetic basis to the disease."

To find out more, researchers collaborated with teams in London and New York to analyse the genetic data of nearly 500 MacTel patients, and 1,700 people without the disease.

Professor Bahlo said they carried out statistical analysis of DNA data from about 6 million markers in the genome of patients with the condition and then compared them to those without.

They found genetic similarities in five key regions of the genome.

Professor Bahlo said four of the five genome regions identified were connected with two crucial amino acids and the fifth region was connected with the size of blood vessels in the retina.

She likened the discovery of the five genetic risk locations to a "treasure map" and said scientists would now keep digging to find out more about the genes associated with MacTel.

Professor Bahlo said they hoped the discovery would eventually help identify people at risk of developing the eye disease.

"For the first time we know a pathway to investigate the future by medical research with future studies in the lab," she said.

"We'll try and validate those findings further. But we've also got some potential biomarkers which will help us diagnose the disease, which is difficult to diagnose, and just pinpoint people who may have faster or slower progression."

The study will be published in the journal Nature Genetics.

Americans Are Terrified of Going Blind – Esquire.com

Tuesday, February 28th, 2017

Americans are a fearful lot. In 2016, one survey found 60 percent of Americans feared corrupt government officials, 41 percent feared a terrorist attack, and 35.5 percent were afraid of Obamacareall fears they channeled into an election. In a separate survey conducted at Johns Hopkins, a majority of Americans (47.4 percent) said loss of sight was the "worst possible" health problem someone could go through. Now, ironically, 56 percent of Americans are afraid they'll lose their health insurance. Blindness, for those keeping track, is often preventable with regular healthcare.

Why Lying Is So Damn Easy for Some People

Advertisement - Continue Reading Below

In a study of 2,044 adults, blindness was ranked as more dreaded than loss of hearing, memory, speech, a limb, or contracting HIV/AIDS, according to The New York Times, because it would have the worst perceived effect on quality of life and a person's independence. Adult blindness is usually caused by four diseasescataracts, glaucoma, diabetes, and age-related macular degenerationthe signs of which can be detected pretty early on by an eye doctor.

With access to an ophthalmologist and a desire for preventative healthcare, that's one major American fear taken care offor now. Shall we tackle government corruption next?

The sorghum plant that could tackle blindness – Devex

Monday, February 27th, 2017

Sorghum farmer Dorothy Warubua in Kiatine Village, Kenya. Photo by: CropLife

Up to half a million children around the world are going blind every year due to a lack of Vitamin A in their diets. According to the World Health Organization,Vitamin A deficiency, which afflicts 250 million children worldwide is the leading cause of preventable blindness in children and increases the risk of disease and death from severe infections. It is a public health problem in more than half the worlds nations, especially in Africa and Southeast Asia, affecting young children and pregnant women in low-income countries the hardest.

In Kenya, scientists are tackling this problem by developing biofortified sorghum, a staple crop that has been genetically modified to contain higher levels of Vitamin A. More than 300 million sub-Saharan Africans depend on sorghum as their primary calorie source. Its drought- and heat-tolerant properties mean it is a vital crop in drought-prone countries, where irrigation is not always accessible or affordable. Improving the nutritional level of staple crops can provide both food and nutritional security.

TheAfrica Biofortified Sorghum, or ABS, project is a public-private partnership established to tackle chronic Vitamin A deficiency in children, as well as improve levels of zinc and iron. If it gets commercial approval, it will be the first-ever biotech sorghum on the market. LikeGolden Rice, biofortified sorghum is a cutting-edge approach to food security and quality.

In terms of tonnage, sorghum is Africas second most important cereal and because it originated in east Africa, Africans know how to plant, cook and eat it. Dr. Titus Magomere, a lecturer in biotechnology at Kenyatta University,is one of 70 scientists involved in the ABS project. He says it is the obvious crop to focus on.

With the work that I am doing with biofortified sorghum, we are not trying to change the way people live, we are just improving the available nutrients in what they already have, he said.

Dr. Magomere and his team have already increased the Vitamin A available in sorghum test plants.

This is the first step, he explained. The second step has been to increase availability of iron and zinc and this has been done by reducing the levels of a protein that binds iron and zinc in the plants. We hope once the product is ready, a meal of sorghum, which will be available to the local farmers, will reduce nutritional deficiencies significantly.

Farmers like Dorothy Warubua from Kenya are hoping to take these scientific advancements from the lab to the fields.

With the work that I am doing with biofortified sorghum, we are not trying to change the way people live, we are just improving the available nutrients in what they already have.

When I was young, many people grew sorghum, but then people were encouraged to grow other crops, and started looking down on sorghum, she said.

Farmers were encouraged to grow maize in particular, but after a number of poor harvests, the Kenyan Ministry of Agriculturesupported the reintroduction of sorghum.

Sorghum needs very little rain. If you plant sorghum and maize at the same time, the sorghum will succeed but the maize often will not so that's why we prefer sorghum, says Warubua.

A reliable harvest also means a more secure source of nutrition and income for farmers and their families.

You have to have a farmer who is going to harvest so that the people will eat, emphasizes Warubua.

WithFood Heroeslike Warubua growing food for her community, and Magomere enhancing micronutrients in staple crops, the chronic nutritional deficiencies that haunt millions of African children can start to be addressed.
