Geographic Atrophy (GA)

Geographic atrophy may be considered the end stage of dry age-related macular degeneration (AMD), causing severe vision loss. Over time, sometimes over many years, the atrophy of the RPE cells (due to drusen deposits in the retina) gets more prevalent with all of the macula being affected.

Geographic atrophy looks like a circle or spot of degeneration, right in the center. Also see Age-related Macular Degeneration.
