Kang JW, et al. – A retrospectively reviewed is conducted to examine the correlation of superficial and deep capillary plexuses utilizing optical coherence tomography (OCT) angiography with visual acuity in eyes with retinal vein occlusion (RVO). The OCT angiography allows to detect foveal avascular zone (FAZ) enlargement, increased parafoveal capillary nonperfusion, and reduced parafoveal vascular density (VD) in eyes with RVO. The area of superficial FAZ and the parafoveal VD are correlated with best–corrected visual acuity in eyes with RVO.
