Fig. 1 — B-scan pictures showing the automatic segmentation of the vascular plexuses. The superficial capillary plexus (a) is automatically segmented using as inner boundary the Z_ILM (internal limiting membrane layer) and as outer boundary the Z_IPL (inner plexiform player). The deep capillary plexus (b) inner boundary is Z_IPL, while the outer is Z_OPL (outer plexiform layer). The OPL is estimated as Z_RPE (retinal pigment epithelium layer) - 110 μm, and the Z_IPL is calculated as: Z_ILM + 70%*(T_ILM-OPL). The choriocapillaris (c) inner boundary is Z_RPE + 29 μm, and the outer is Z_RPE + 49 μm. Violet dashed lines designate the boundaries, while red and green spots respectively represent the perfusion above and below the RPE
