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.
