氩激光治疗视网膜分支静脉阻塞的视网膜新生血管

报告氩激光治疗视网膜分支静脉阻塞新生血管30例，对照组34例。激光散点光凝无灌注区和新生血管可使新生血管消退，玻璃体出血发生率降低。本组治疗后新生血管完全消退者23例，缩小者7例。玻璃体出血者对照组为70.6%，激光组在治疗前为43.3%，治疗后尚无一例发生。激光组视力比对照组者明显进步(P<0.005)。激光治疗效果与新生血管的大小，位置及是否突入玻璃体内有关。我们还讨论了激光治疗的方法、时机和预后。（中华眼底病杂志，1994，10：195-198）

ARGON LASER PHOTOCOAGULATION FOR THE RETINAL NEOVASCULARIZATION IN BRANCH RETINAL VEIN OCCLUSION

The effect and opportunity of argon laser photocoagulation for the retinal neovascularization in branch retinal vein occlusion in 30 patients were investigated with a control group of 34 patients received nonlaser but routine treatment. The results of the therapeutic effect demonstrated that the neovascularization disappeared completely in 23 cases and became smaller in 7 cases after laser photocoagulation. The incidnce of vitreous hemorrhage in laser group was 43.3% before laser treatment and none after treatment in the duration of observation,and 70.6% in control group. The progression of visual acuity after treatment in laser group was much better than in control group(P＜0. 005)at the time of the latest examination. We found the therapeutic effect was relation to the area, location of the neovascularization in retina,as well as whether the new vessels protruding into vitreous or not.（Chin J Ocul Fundus Dis,1994,10:195-198）
