本文报告黄斑分支静脉阻塞４４例，分析了该病的临床表现和视力预后。黄斑分支静脉阻塞与主干分支静脉阻塞相同，恒发生在动、静脉交叉处。本组阻塞点处动脉位于静脉之上者占９３．０２％，阻塞部位以位于黄斑第二分支者最多占５９．１％。本组并发症少，无１例产生新生血管。视力预后好，追踪最后视力≥０．５者占８６．４％。 This article reports 44 cases of macular branch vein occlusion, analyzed the clinical manifestations and visual acuity prognosis. Macular branch vein occlusion and trunk branch vein occlusion the same, constant occurred in the arteriovenous cross. This group of obstruction artery at the veins located above 93.02%, blocking the site to the macula in the second branch accounted for up to 59.1%. Less complications in this group, no case of neovascularization. Vision good prognosis, tracking the final visual acuity ≥ 0.5 accounted for 86.4%.
