Spectral-domain (SD-OCT) optical coherence tomography of a healthy retina (OS): Scan parameters: infrared scan angle 30°; OCT scan angle 20°; pattern size 20°×15°, 19 sections (244 μm between B-scans). (a) Conventional fundus camera image. (b) SD-OCT en-face image showing overlaid OCT scan lines (green) and scan area. The green arrow shows the position of the scan line used to generate the cross-sectional retinal OCT image (i.e., (c)). (c) Cross-sectional image of the retina depicts the vitreous cavity (upper, optically clear area), the internal limiting membrane (segmented by the upper red line marked ILM, the intervening retinal layers, Bruch's membrane which is segmented by the lower red line marked BM, and the underlying choroid (lower). The vertical green line defines the position of the retinal thickness measure along the cross-sectional retinal thickness profile. (d) Cross-sectional retinal thickness profile corrected for tilt.
