Age-related Macular Degeneration
Along with wet AMD, Geographic atrophy (GA) is an advanced form of AMD in which large, well-demarcated sections of the retina stop functioning. It leads to irreversible vision loss. GA can occur late in the progression of dry AMD, but can also occur even after wet AMD has developed and after the use of anti-VEGF injections to stop wet AMD. Patients with GA can also develop wet AMD.
