Macular regions analyzed by spectral-domain optical coherence tomography scan in the retinal thickness map analysis. a The thickness of the parafoveal area (red circle) ranging from 1 to 3 mm from the subfoveal region was analyzed. Representative B-scan images of the control group (b) and the CRVO group (c). The boundaries of the fundus structure were segmented by an automated algorithm. CRVO, central retinal vein occlusion; NFL, nerve fiber layer; GCL, ganglion cell layer; IPL, inner plexiform layer; INL, inner nuclear layer; OPL, outer plexiform layer; ONL, outer nuclear layer; PRL, photoreceptor layer; RPE, retinal pigment epithelium
