Optical coherence tomography angiography (OCTA) images showing vessel density analysis of the superficial and deep retinal capillary plexuses (SRCP and DRCP) and the intraretinal layers analyzed by custom software. OCTA images of the SRCP (a1) and DRCP (a2) in the 3 × 3-mm area around the fovea. Binary images of the microvascular network in the SRCP (b1) and DRCP (b2) showing the density in the annular zone with a diameter of 2.5 mm after excluding the foveal avascular zone (diameter = 0.6 mm). c1 The SRCP (red) is shown as a slab extending from the internal limiting membrane to 9 μm above inner plexiform layer (IPL). c2 The DRCP (blue) is shown as a slab extending from 9 μm above IPL to 9 μm below outer plexiform layer. d Intraretinal layer structures in horizontal scan OCT images: RNFL, retinal nerve fiber layer; GCL-IPL, ganglion cell layer plus inner plexiform layer; INL, inner nuclear layer; OPL, outer plexiform layer
