(a) OCT radial scan. ETDRS map: (b) retinal pigment epithelium and photoreceptor outer segment (RPE-OS) layer thickness (extending from the inner segment/outer segment (IS/OS) layer to the outer surface of RPE); (c) the outer nuclear layer and photoreceptor inner segment (ONL-IS) thickness (measured from the interface between the outer plexiform layer (OPL) and the outer nuclear layer (ONL) extending to the IS/OS layer); (d) choroidal thickness (CT) measured from the outer surface of RPE to the manually drawn sclerochoroidal interface.
