Image segmentation and thickness of chorioretinal layers in rhesus macaques. A high-resolution histological section (A) and SD-OCT image (B) of normal maculae from adult rhesus macaque eyes before (top panels) and after (bottom panels) image segmentation. Retinal and choroidal thickness measurements across the central 3 mm segment around the fovea, as well as individual sublayers are compared between histology (C) and SD-OCT (D). Cumulative thicknesses are measured from Bruch’s membrane, which is designated at zero. Scale bars: 200 μm. The line graphs in (C) and (D) are not drawn to the same scale as the SD-OCT and histological images in (A) and (B). Abbreviations: NFL, nerve fiber layer; GCL, ganglion cell layer; IPL, inner plexiform layer; INL, inner nuclear layer; OPL, outer plexiform layer; ONL, outer nuclear layer; ELM, external limiting membrane; IS, photoreceptor inner segments; OS, photoreceptor outer segments; RPE, retinal pigment epithelium; CC, choriocapillaris; OC, outer choroid.
