[方法]以单绿色氩激光治疗25只视乳头旁新生血管膜,取纯绿色514.5nm波长光束,强度为50～250mW,时间0.5s,光斑约50～250μm。治疗区以视网膜色素上皮呈灰色为宜,避免在视网膜层形成白斑。整个新生血管膜按McMeel报道的方法作融合性激光光凝。疗后定期进行检查,末次检查如符合下列条件,则为有效:(1)视力无变化,或较治疗前有改善;(2)暗点小于治疗前;(3)出现 [Method] The 25 neovascularization neovascularization films were treated by single green argon laser. The pure green color was 514.5nm. The intensity was 50 ~ 250mW, the time was 0.5s and the spot size was about 50 ~ 250μm. Treatment area to the pigmented retinal pigment gray is appropriate to avoid the formation of white spots in the retina. The entire neovascular membrane was fused to laser photocoagulation as reported by McMeel. After treatment, regular inspection, the final inspection if the following conditions are valid: (1) no change in vision, or better than before treatment; (2) dark spots less than before treatment; (3) there
