视网膜静脉阻塞(RVO)是眼科常见病,也是视力障碍的主要原因。RVO分为视网膜中央静脉阻塞(CRVO)及视网膜分支静脉阻塞(BRVO)。BRVO多见于年长者,几乎无例外的发生在视网膜动静脉交叉处,视网膜动脉硬化是其主要原因。CRVO较少见,其病因复杂,治疗较棘手,50岁以下者时有发生。本文将CRVO的发病机制、临床表现及诊治概述如下。 Retinal vein occlusion (RVO) is a common ophthalmopathy and is also a major cause of visual impairment. RVO is divided into central retinal vein occlusion (CRVO) and retinal branch vein occlusion (BRVO). BRVO more common in older persons, almost without exception occurred in the retinal artery and vein intersections, retinal atherosclerosis is the main reason. CRVO is rare, its etiology is complex, the treatment is more difficult, patients under the age of 50 have occurred. This article will CRVO’s pathogenesis, clinical manifestations and diagnosis and treatment are summarized as follows.
