视网膜分支静脉阻塞的临床分析

目的 为了了解视网膜分支静脉阻塞患者的合并症发生的情况。 方法 回顾性地分析本院1995年10月到1999年10月277例（277只眼）视网膜分支静脉阻塞的病例。 结果 70%以上的病例发病年龄均在55岁以上，81.58%的分支静脉阻塞发生于颞上及颞下象限。分支静脉阻塞合并症的发生率与阻塞的位置密切相关，愈大的分支静脉阻塞，其无灌注区及新生血管的发生率也就愈高。 结论 视网膜分支静脉阻塞黄斑水肿发生在发病的早期，无灌注区的出现多在7～12个月，而新生血管的出现，多半在一年以后，因此对这些患者应当有更长期的追踪观察。 （中华眼底病杂志，2002，18：17-19）

Clinical analysis of branch retinal vein occlusion

Objective To investigate the complications of the Branch Retinal Vein Occlusion. Methods Two hundred and seventy seven cases (277eyes) of branch retinal vein occlusion (BRVO) have been studied retrospectively from 1995 October to 1999 October. Results Most cases of BRVO occured after the age over fifty five. About 81.85% BRVO affected at supiriotemporally and inferiotemporally. The incidence of the complication of BRVO is closely related to the site of obstruction, the larger branch vein occlusion the higher incidence of the nonperfusion area and neovascularization. Conclusion The macular edema occured in the early stage of the BRVO, and most non perfusion areas were observed between six to twelve months. The neocvscularization always observed after one year later from the vein obstruction. So that the patient have to be followed carefully with a long duration.
