Description
Summary:Purpose To determine the prevalence of vitreovascular traction at the obstruction site in patients diagnosed with branch retinal vein occlusion (BRVO). Methods In this prospective observational case‐control study thirty‐two consecutive cases of BRVO were studied with spectral‐domain optical coherence tomography (SD‐OCT) to detect the presence of vitreovascular traction or vitreous adhesión at the occlusion site. The fellow eye was used as control. Results SD‐OCT directed to the occlusion site revealed a vitreovascular traction in eight eyes (25%). In fourteen eyes (43.75%) an adherent posterior hyaloid without signs of traction was found. Regarding to the same vessel segment of the fellow eye, none of the controls revealed vitreovascular traction, while vitreous adherence was present in 12 (37.5%). Vitreovascular traction at the occlusion site was significantly associated with BRVO (p=0.024, Chi‐squared test). Conclusion Vitreous traction at the occlusion site could play a role in the etiology of some cases of BRVO.
