摘要
目的:分析视网膜分支静脉阻塞不同发病阶段的激光治疗疗效。方法:按病程将患者分为A组:1个月≤病程<3个月(40例);B组≥3个月(38例),两组均采用象限和/或后极部格栅样光凝法,记录两组的阻塞部位,激光前后视力,眼部新生血管消退率,黄斑水肿吸收情况及光凝参数。结果:两组在光凝次数及点数方面均无显著差异;光凝后两组视力均有提高;B组光凝前眼底新生血管总发病率为41%,10%伴有少量玻璃体出血,A组为0;光凝后B组新生血管消退率为90%,A组无灌注区(NPA)消退率100%;黄斑水肿的好转率:A组为82.5%,B组为79%,两组均未见明显的并发症。结论:病程在1-3个月之间NPA≥5PD光凝安全有效。
Objective： Analysing the therapeutic effect of laser treatment in the different phase of branch retinal vein occlusion （BRVO） for the propose of offering strategic time option of treatmant.Methods： Patients were divided into two subgroups according to onset history, group A（40 cases） is those with history longer than 1 month and less than 3 months, while group B （38 cases） is those longer than 3 monthes.Two groups patients were treated with scatter and/or grid laser photocoagulation.The site of occlusion, total laser bums and visual acuity （VA）, neovascularization （NV）, maculopathy before and after treatment were recorded.Results： There were no significant difference on the site of occlusion and laser bums between two groups. The VA were enhanced after treatment in both groups.Total incidence of fundus NV before treatlnent in group B was 41%, include 10% few vitreous hemorrhage as oppposed to 0 in group A.90% NV obliterated after treatmentin group B.NPA in A group 100% obliterated.The total resolution and .alleviation rate of （cystoid） macular edema was 82.5% and 79% in group A and B respectively. Condusions： Laser treatemnt given between 1 and 3 months with NPA≥5PD after onset is beneticial and safe to the patients.
