Genetic Testing for Macular Degeneration - by Dr Jennifer Carter

Macular Degeneration

He stood over 6 feet and closely resembled Billy Graham. From the time I entered Optometry school, my grandfather's question to me was "have you found a cure for macular degeneration yet?" As he said this, his eyes appeared to be focused over my shoulder. But in reality, he was using his peripheral vision to see my face. He had learned to compensate for his loss of central vision from age-related macular degeneration (AMD).


If he were still here, he would be amazed at the progress made in diagnosing and treating AMD. At West Georgia Eye Care we are pleased to offer a genetic test which is 99.9% accurate in determining the chances of developing wet AMD. A swab of cells is taken from the cheek to detect certain genetic markers that are known to be indicators for vision loss. These markers are then analyzed along with smoking history to determine the risk of losing your sight.

Early detection and treatment lead to better visual outcomes. The ability to determine levels of risk associated with macular degeneration is invaluable. Macular degeneration cannot be reversed, however vision loss associated with the devastating disease can be delayed if we are aware of your risk.

I sometimes sit back and think what a difference genetic testing would have made for my grandfather. He was nearly blind when he passed away. If he had known his risk years ago and had a personalized program to manage his disease, I believe a more aggressive management would have been chosen. Genetic testing is a small piece of the puzzle, but a very important factor that can help preserve vision.
