An advanced form of dry macular degeneration (AMD), geographic atrophy causes a black spot/vision loss in your central vision, difficulty reading in dim lighting, and glare. Interestingly, your peripheral (side) vision is not affected.
This condition is caused by the development of protein deposits called drusen on the central part of your retina (the macula). The macula is responsible for your central vision. As these drusen deposits increase, they cause your photoreceptor cells to die. Without a healthy number of photoreceptor cells (rods and cones), your eyes are unable to receive light and transmit the electrical impulses to the brain for clear central vision.
Treatment for Geographic Atrophy
Unfortunately, once photoreceptor cells are lost, they cannot be regained. Our retinal specialist in Jacksonville, Dr. Breno da Rocha Lima, uses a variety of techniques to monitor the spreading of drusen and your overall retinal health to help protect vision for as long as possible. Luckily, this is typically a slow process that will not affect peripheral vision.
