Abstract
The photoreceptor (PR) – retinal pigment epithelium (RPE) – choriocapillaris (CC) complex is an extremely important group of layers in the outer retina. We demonstrate resolution of the CC vascular network across the macula, as well as the methodology to extract and quantify structural metrics from all three layers from averaged AO-OCT volumes. In diseased eyes, small changes in CC structure may portend the initiation of disease and therefore the investigation of CC structural changes may aid early disease diagnosis for many diseases, both prevalent and rare, that begin in the outer retina.
