视网膜黄斑分支静脉阻塞的临床研究

目的探讨视网膜黄斑分支静脉阻塞患者的临床特点。方法收集视网膜黄斑分支静脉阻塞患者64例64只眼,分别对其临床表现和荧光素眼底血管造影图像进行分析。结果视网膜黄斑分支静脉阻塞患者的阻塞点多位于黄斑区上下血管弓的动静脉交叉处,且以靠近视乳头上的第一分支静脉好发;荧光素眼底血管造影示早期黄斑分支静脉荧光素充盈迟缓,晚期血管壁着染和荧光素渗漏;最常见的并发症是黄斑囊样水肿。结论视网膜黄斑分支静脉阻塞患者的视力预后随视网膜受累范围及并发症的多少而各异,因其视网膜受累范围较小,产生的并发症较少,故预后较好。

Clinical Study of Macular Branch Retinal Vein Occlusion

Objective To explore the clinical manifestations of the patients with macular branch retinal vein occlusion. Methods Sixty four patients(64 eyes)with macular branch retinal vein occlusion were gathered. The clinical manifestations and the images af fundus fluorescein an- giography(FFA)were analyzed. Results The obstructive site in the patients with macular branch retinal vein occlusion were often found at the artery and vein cross of the arch near the macula, especially the first macular branch vein near the optic. The images of FFA showed fluorescein filled late of macular branch vein at the early phase, and fluorescein staining and stained vascular wall at the late phase.The most frequent com- plications was the cystoid macular edema. Conclusion The visual prognosis of the patients with macular branch retinal vein occlusion is different due to the occlusion areas and the number of the complications. The less occlusion areas were involved and complications occurred, the better was visual prognosis.
