532 nm绿激光治疗33例(36眼)缺血型视网膜中央静脉阻塞

目的：了解532 nm绿激光全视网膜光凝术（Panretinal photocoagu lation,PRP）治疗缺血型视网膜中央静脉阻塞（Central retinalvein occlusion,CRVO）的临床疗效。方法：依据眼底荧光血管造影（FFA）结果,33例36眼被确诊为CRVO;使用532 nm绿激光对此36眼进行PRP;光凝后每2周复查眼底,每3个月复查FFA,并随诊观察6～12个月。结果：本组病例PRP后6月时8眼（24.2%）视力提高,23眼（69.7%）视力无变化,5眼（15.1%）视力下降。27眼有效,总有效率为81.8%。结论：532 nm绿激光视网膜光凝术治疗缺血型视网膜中央静脉阻塞是安全、有效的。

Treating ischemic central retinal vein occlusion by 532 am Green Laser

Objective:To evaluate the clinical effect of treating ischemic central retinal vein occlusion(ischemic CRVO) by pan retinal photocoagulation(PRP) with 532 nm Green Laser.Methods:According to the results of fundus fluorescence angiography(FFA),33 cases(36 eyes) had been diagnosed as ischemic CRVO and been observed;And PRP were performed on the cases.After PRP,the cases were examined fundus every 2 weeks,and were performed FFA every 3 months.The regular follow-up lasted for 6 ~ 12 months.Results: The visual acuity of the cases was improved in 8 eyes(24.2%) after PRP 6 months,and no changes in 23 eyes(69.7%),and decrease in 5 eyes(15.1%);and 27 eyes(81.8) were proved effective.Conclusions: It is safe and effective to treat ischemic CRVO by pan retinal photocoagulation with 532 nm green laser.
