OCT aspect of macular DRIL. (a) Disorganization of the inner retinal layers (DRIL). (b) Normal macular segmentation. (c) Magnified segment of the first image (a); global disruption of the ellipsoid zone and RNFL. ILM: internal limiting membrane; RNFL: retinal nerve fiber; GCL: ganglion cell layer; IPL: inner plexiform layer; INL: inner nuclear layer; OPL: outer plexiform layer; ONL: outer nuclear layer; ELM: external limiting membrane; PR/EZ: photoreceptor layer/ellipsoid zone (inner and outer photoreceptor segment junction); RPE: retinal pigment epithelium.
