© Springer India 2017. Geographic atrophy (GA) represents a common end stage of various retinal diseases including advanced age-related macular degeneration (AMD). While choroidal neovascularization (CNV) is the most common cause of acute severe visual loss in AMD, approximately 20 % of AMD patients who are legally blind have lost central vision due to GA (Friedman et al. 2004; Klaver et al. 1998; Klein et al. 2002; Mitchell et al. 1995; Sunness et al. 1999).
