Rebolleda G, et al. - Authors evaluated the superficial peripapillary vascularization in non-arteritic anterior ischaemic optic neuropathy (NAION) at acute and atrophic (3 months) stage. In NAION, a significant peripapillary microvascular dropout was demonstrated by both strategies, but the customized analysis detected them ­earlier. Within the first 3 months, a progressive vessel reduction occurs, which correlates with ganglion cell-inner plexiform layer (GCIPL) thinning.
