Figure 1: Quantification from optical coherence tomography images. (a) Cross-sectional OCT image at a yellow line in (c), where green lines in (a) show the detected layer information for calculating the retinal nerve fiber layer (RNFL) thickness; (b) RNFL thickness map, where the number indicates the thickness in micrometers in 12 sectors around the optic disc and cyan and magenta circles show automatically detected disc and cup boundaries; (c) a color fundus photo of the optic disc area.
