Association of Foveal Avascular Zone Diameter with Best-Corrected Visual Acuity in Diabetic Retinopathy: A Cross-Sectional Optical Coherence Tomography Angiography Study
Background: Foveal avascular zone (FAZ) enlargement reflects capillary loss in diabetic retinopathy (DR), but its relationship with visual acuity varies across protocols and populations. Objective: We assessed the association between swept-source optical coherence tomography angiography (OCTA)-derived FAZ diameter and...
