Retinal Vessel Density in Optical Coherence Tomography Angiography in Optic Atrophy after Nonarteritic Anterior Ischemic Optic Neuropathy

Figure 2

Box plots showing the retinal vessel density and thickness in nonarteritic ischemic optic neuropathy (NAION) eyes and healthy control (HC) eyes: (a) whole enface image vessel density (wiVD), circumpapillary vessel density (cpVD), and parafoveal vessel density (pfVD); (b) average retinal nerve fiber layer (RNFL) thickness and average ganglion cell complex (GCC) thickness. The median (dark bold line), IQR (box), and the whole range of values (whiskers) are shown. Mann-Whitney tests showed significant reduction in the wiVD, cpVD, average RNFL thickness, and average GCC thickness of the NAION group compared to the HC group.
