Schematic of retinal blood supply. The capillary networks within the RNFL, GCL, IPL, INL and OPL perfuse the inner retina. However, according to a recent study using optical coherence tomography [8], since there are no vessels in the outer retina, choroidal vessels perfuse this region through diffusion. RNFL: retinal nerve fiber layer; GCL: ganglion cell layer; IPL: inner plexiform layer; INL: inner nuclear layer; OPL: outer plexiform layer
