Patient 9. A, B, Fundus photographs depicting the presence of pigments in the peripheral retina of a retinitis pigmentosa patient and the direction of optical coherence tomography (OCT) scans in the macular region. C, D, StratusOCT and ultrahigh-resolution (UHR) OCT images, respectively, of a patient with retinitis pigmentosa. In both images, the outer nuclear layer (ONL) thickness appears normal in the foveal region, but becomes abnormally thin in the periphery of the macula. A close examination of the UHR OCT image reveals the progressive thinning of the inner segments (ISs) and outer segments (OSs) of the photoreceptors outside of the foveal region (red arrows). An enlargement of the UHR OCT image of the retinitis pigmentosa patient clearly indicates the thinning of the ONL and photoreceptor segments when compared with an enlargement of the normal subject from Figure 1. ELM = external limiting membrane; GCL = ganglion cell layer; INL = inner nuclear layer; IPL = inner plexiform layer; IS/OS = junction between the photoreceptor IS and OS; NFL = nerve fiber layer; OPL = outer plexiform layer; RPE = retinal pigment epithelium.
