Geographic atrophy is a form of dry macular degeneration that occurs in the retina (back of the eye). Not every patient with dry AMD will develop geographic atrophy.

Work is currently being done to develop multiple therapies for treatment of geographic atrophy. It is administered via an injection in the eye. It is important to note that treatments do not reverse or stop vision loss; rather, treatment may delay progression of geographic atrophy.

Geographic atrophy can present in different ways to cause changes in vision.

You may see a dark spot, blind spot, or distortion in the center of your vision.

Colors can become dull, vision can become blurry, and you may experience difficulty seeing at night.

This can cause difficulty doing daily activities - such as reading and driving.

Progression of geographic atrophy is gradual and can take months to years for vision to decrease significantly.
