A 65 years old woman with an acute visual loss of her right eye related to NAION. Superficial OCT-A (Angioplex©) of her right eye (a) shows on the nasal side of the optic disc a dilation of the capillaries, which appear tortuous (arrowheads). On the temporal side, there are some dark areas corresponding to a vascular drop out (arrows). The B-scan inferior to the optic disc shows that there is no edema in the vascular dropout area, and thus no shadowing artifact (c). In the healthy eye (b and d), the peripapillary network appears regular with no vascular dropout. Green arrows within the OCT-A images indicate the location and direction of the B-Scans
