Differences in macular capillary parameters between healthy black and white subjects with Optical Coherence Tomography Angiography (OCTA).

In our study, our black subjects had decreased macular capillary vasculature compared to matched white subjects, even in early adulthood and the absence of any systemic or ocular conditions. To our knowledge, this is the first report showing that retinal and choriocapillary vascular differences may contribute to racial disparities in vulnerability to DR.
