Vision-Eye Chart A Year Ago

Eye Chart
A Year Ago
11" x 14"
Yesterday, I wrote about seeing the eye chart in a different doctor's office while my aunt was getting her eyes checked. I have posted this painting before in my Vision series. I wanted to show it again as a comparison to the eye chart as I saw it last January and the chart that I saw this week.
Recently, I joined a list or forum online for MD (Macular Degeneration) support. There are people on there of all ages and who have, or someone in their life has, MD or some similar vision problem. There are some very knowledgeable, highly qualified, and experienced people on the list. I have put a link to this group and others under Eye Sites on my sidebar.
Richard Trevino is one of the helpful people on the list. I wrote a little about the online vision test for MD that he has developed in a previous post.
Information about the test, and the test itself, can be found at . You can find out more about Richard Trevino on his website which I have listed under Interesting Sites in my sidebar.
I'm not a professional, by any means, and didn't even need glasses except for close, small things like threading a needle or reading computer printouts, until recent years. So, I do not feel very experienced in vision problems. I am trying to learn all I can and prepare myself as best as I can for this journey. And I am trying to share what I learn and experience in order to help others who find themselves, or someone in their lives, in a similar situation.
I took the test at and found my results. Each time I check my vision on the test, now, it will tell me if my vision has changed by comparing the results to my previous visits.
I was curious about the test and the man who created it. So, I wrote to him and asked for information. I also told him that I wanted to share with my readers. He was kind enough to send me some very interesting information that I think is important to know. He certainly seems well-qualified to develop and offer this test and information to benefit the public.

Richard Trevino's ultimate goal is to improve the ability of people with macular degeneration to test their vision at home between visits to the eye doctor. This is important because, if bleeding occurs, doctors want to get treatment started as soon as possible to prevent permanent vision loss. There has been great progress over the past several years in the treatment of wet macular degeneration (Avastin, Macugen, Lucentis, etc.), but the ability to reach people that need this treatment has lagged. There is good research that is pointing in the direction of an online vision test. The exact form that the ideal vision test will take is unclear.
Trevino's project is the first of its kind. It is just a prototype. It is a proof of concept that vision testing over the internet for patients with macular degeneration is possible, and that people will use it and can benefit from it. It is still very much a work in progress. He is continually adjusting it in reponse to feedback from users. He also plans to develop other vision tests using different testing strategies in an attempt to find one that works best. So this project is still very much in its infancy.
Trevino has given presentations and he is writing papers to try to raise awareness among optometrists of the need for imporoved home vision testing for patients with macular degeneration. You can find a powerpoint presentation that he gave to a group of optomoetrists on this topic at
He has also written a paper on this topic that will be published in the "Journal of the American Optometric Association" in July, 2008. A second paper is currently being written, which he hopes to have published later in the year.
Trevino has approached several researchers about doing a study using MVT (My Vision Test), but has been unable to get anyone interested to date.
Trevino is a practicing optometrist, and works at a Veterans Administration medical center in Evansville, Indiana. He has an interest in research and teaching, and has published numerous papers in the optometric literature over his 20 + year career.
He developed an interest in computers in the early 1990s and has become quite a computer geek. He taught himself computer programming, and has developed numberous web sites and computer programs over the years. He never charges for his services, as he does it just for the fun and personal satisfaction that he derives from helping others.
He has no intention of ever charging people to use MyVisionTest.
Trevino got the idea for developing an online vision test for macular degeneration after reading several research papers by scientists that were trying to develop a better vision test for macular degeneration.. Although these papers were published years ago, and the results of the research was very promising, he was unable to find anything available on the internet for people to use. So, he decided to do it himself.
Currently, patients are advised by their doctors to use the Amsler Grid daily to check for changes in their vision. This is given in the form of a chart printed on heavy paper or even in a brochure. There are also examples of the Amsler Grid online. If changes are detected, patients are instructed to contact their Retina Specialist immediately. Time is very important in preventing futher damage due to a bleed or fluid leaking.

My thanks to Rick for providing the information about himself, and for his work with those who have, or will have, vision loss.
Please share this with anyone who you think might be interested. Thanks for reading. I do welcome your comments and your support.
