Fundus Autofluorescence Patterns of Geographic Atrophy Patterns. The Fundus Autofluorescence in Age-related Macular Degeneration (FAM) study categorized geographic atrophy eyes into five distinct phenotypes: none, focal increased, banded, patchy, and diffuse. The pattern is presented in pairs, with the baseline FAF image on the left and the follow-up FAF image on the right (follow-up ranged from 12 to 25 months). Diffuse pattern is further divided into reticular, branching, fine granular, fine granular with peripheral punctate spots and trickling.
