๐Overview
Geographic atrophy (GA) is an advanced form of dry age-related macular degeneration (AMD) characterized by progressive degeneration and loss of retinal cells, particularly the retinal pigment epithelium (RPE) and photoreceptors, leading to well-demarcated areas of atrophy in the macula. It is a leading cause of irreversible vision loss in older adults.
