532nm绿激光治疗33例(36眼)缺血型视网膜中央静脉阻塞

Treating ischemic central retinal vein occlusion by 532nm Green Laser

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。

Objective：To evaluate the clinical effect of treating isehemie central retinal vein occlusion （ischemic CRVO） by pan retinal photocoagulation （PRP） with 532 nm Green Laser. Methods：According to the results of fnndus fluorescence angiography （FFA） ,33 eases （36 eyes） had been diagnosed as isehemie CRVO and been observed; And PRP were performed on the eases. After PRP, the eases 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 eases 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.
