【摘要】 目的 :分析视网膜静脉阻塞患者中心凹两侧视网膜的光学相干断层成像 (OCT)特征。方法 :40例视网膜静脉阻塞患者 ( 4 0眼 )行OCT检查。其中CRVO 3 0例 ,BRVO 10例。结果 :CRVO中心凹鼻侧视网膜厚度大于颞侧 ,BRVO中心凹阻塞侧视网膜厚度大于对侧。阻塞远端的视网膜结构变化较小 ,阻塞近端的视网膜结构变化较大。结论 :OCT可以有效地观察视网膜静脉阻塞患者后极部中心凹两侧视网膜的变化 ,静脉阻塞近端的视网膜结构损害比远端更加严重。更多还原

【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.更多还原
