Abstract

Objective:To observe the changes in retinal thickness around the fovea in retinal vein occlusion (RVO). Methods:There were 40 eyes of patients including 30 eyes of central retinal vein occlusion (CRVO) and 10 eyes of branch retinal vein occlusion (BRVO) involved in the study.10 eyes of 10 healthy volunteers served as control group.Optical coherence tomography (OCT) was performed with 2 radial scans centred on the fovea. Results:OCT supplied detailed images of retinal structure in retinal vein occlusion.The nasal rim of fovea (472.30±152.84μm) was thicker than that of temporal rim (390.43±123.96μm) in CRVO.The affectd rim of fovea (513.20±230.32μm) was thicker than that of the opposite rim (335.60±103.41μm) in BRVO. Conclusions:Retinal damage near the occlused site is more severe than that far away in RVO.OCT could reveal minor changes in retinal architecture that can be visualized difficultly following retinal vein occlusion.
