Tsuboi K, et al. - Using projection-resolved optical coherence tomography angiography (PR-OCTA), researchers assessed vascular alterations in branch retinal vein occlusion (BRVO) in this retrospective review of 30 consecutive eyes of 30 cases with BRVO. Vessel density (VD) and retinal thickness alterations in the superficial capillary plexus (SCP), intermediate capillary plexus (ICP), and deep capillary plexus (DCP) were assessed as the main outcome measures. Three different vascular plexuses were shown by PR-OCTA in BRVO. No alteration was evident in the VDs, during the observation period, in the SCP and DCP. During remission, a significant rise in the VDs was seen in the ICP. The projection artifacts and segmentation errors despite using PR-OCTA were held responsible for the possible VD increases in the ICP induced by inner retinal thinning.
