(A) B-scan cross section of rat retina with layer boundaries segmented. (B) Flattened structural B-Scan overlapped with angiography. (C) Averaged structure and angiography z-profiles. The structural z-profile (green curve) displayed the reflectance variation of layers, where the NFL, IS/OS and RPE appeared as the brightest layers in the retina and the ONL was the darkest. The angiography z-profile (red curve) showed peaks at three distinct inner retinal plexuses and choriocapillaris. NFL: nerve fiber layer, IPL: inner plexiform layer, INL: inner nuclear layer, OPL: outer plexiform layer, ONL: outer nuclear layer, ELM: external limiting membrane, IS/OS: inner and outer photoreceptor segment, RPE: retinal pigment epithelium, CC: choriocapillaris. SVP: superficial vascular plexus, ICP: intermediate capillary plexus and DCP: deep capillary plexus. (D) The thicknesses of GCC, OPL, ONL and total retina calculated from the segmentation results. ELM thickness could not be measured with this method. GCC: ganglion cell complex, TR: total retina. Scale bar = 100 μm.
