What is Geographic Atrophy?

What is Geographic Atrophy?

Geographic Atrophy (GA) is an advanced form of age-related macular degeneration (AMD), which is a progressive, irreversible condition of the eye that causes severe vision loss.

GA disease starts around the center of the macula (the part of the eye that is responsible for sight in the center of the field of vision).

Early in the disease, your vision may still be good; however, as GA progresses, the photoreceptor cells in the eye (cells that gather light and send images to the brain) slowly die off, causing dark or missing spots to appear in the center of your vision.1

The result is a gradual loss of central vision, which can make performing everyday activities, such as reading, driving, and climbing stairs, difficult.2

Currently, there are no approved treatments or a cure for GA.
