Geographic Atrophy

PR-RPE loss ratio and FAF patterns identified as key predictors of geographic atrophy progression

Ratio of photoreceptor (PR) to retinal pigment epithelium (RPE) loss, along with specific fundus autofluorescence (FAF) patterns like "diffuse" and "diffuse trickling," can serve as key biomarkers for predicting the progression of geographic atrophy (GA), according to a study. The study analyzed multimodal imaging from 87 treatment-naïve patients with GA...
