Why it is critical to recognize GA at first sight

GA is an advanced form of age-related macular degeneration (AMD).1-3 It is a leading cause of significant vision loss worldwide.1,4,5

While lesion growth in GA may appear to proceed slowly, disease progression is relentless and irreversible.5-8 Of the 397 patients who developed central GA, the median time to foveal encroachment was only 2.5 years from diagnosis according to a prospective AREDS study (N=3640).6 It is critical to diagnose and refer early because the damage is progressive and associated with irreversible vision loss.3,5,7-9
