A. 20° IR-SLO image with BMO points (yellow markers) and best fit ellipse (red). The green ellipse illustrates the scan path for the B-scan used for RNFL analysis in B. Interpolated B-scan with RNFL borders segmented. RNFL thickness was calculated after removing major retinal vasculature (blue). C. 20° IR-SLO image with 24 line radial scan D. 30° IR-SLO image with choroid thickness map. The green, yellow and blue ellipses correspond to eccentricities from the BMO of 500μm, 1000μm, and 1500μm. E. Enhanced horizontal radial b-scan (red line in C) through the ONH illustrating the segmentation for ILM, BM, choroid, and lamina, and reference points for the BMO and 4mm plane.
