    Retinal Vessel Density in Exudative and Non-Exudative Age-Related Macular Degeneration on Optical Coherence Tomography Angiography

    Importance Although the choroid contributes to the pathogenesis of age-related macular degeneration (AMD), the role of retinal perfusion is unclear. Purpose To compare retinal vascular measurements between eyes with non-exudative and exudative AMD using optical coherence tomography angiography (OCT-A). Design Retrospective, cross-sectional study. Methods OCT-A images were analyzed from 310 eyes of 182 patients (mean age 78.8±8.8) with non-exudative (54.2%) and exudative (45.8%) AMD to measure retinal vessel density (VD) from the superficial capillary plexus in the foveal, parafoveal, and full macular regions and foveal avascular zone (FAZ) area, perimeter, and circularity. Multivariate regressions were ...
