黄斑分支静脉阻塞荧光血管造影分析

Analysis on the fluorescent angiography of macular branch retinal vein occlusion

目的 :分析视网膜黄斑分支静脉阻塞 (MBRVO)的荧光造影改变和临床特点。方法 :收集 90例 91只眼MBRVO患者的荧光造影照片 ,分析黄斑分支静脉阻塞的部位及特点。结果 :MBRVO占同期分支静脉阻塞的 14 0 % ;阻塞部位以黄斑颞上支多见 ,占 71 4% ;动静脉交叉呈正交叉者为 98 9% ;黄斑水肿发生率为 93 4% ;出现缺血改变占 16 5 % ;对侧眼出现静脉阻塞者为 5 5 %。结论 :MBRVO的发病与BRVO的病因及受累部位相似 ,视力预后取决于其并发症的程度及范围。

Objective:To explore the changes in fluorescent angiography and the clinical features of macular branch retinal vein occlusion (MBRVO). Methods:The data of fluorescent angiography for 90 patients (91 eyes) with MBRVO were analyzed. Results:In 71 4% of the eyes,the occlusion site was at the superior-temporal macular branch,especially the second crossing site (69 2%) in which 98 9% of the cross sign were artery anterior to the vein.The prevalence of macular cystoid edema was 93 4%.The ischemic changes were found in 16 5% and the neovascularization was seen in three cases.5 5% of the patients had vein occlusion in the fellow eye. Conclusions:The etiology and occlusion site of MBRVO was similar to the branch retinal vein occlusion.
