摘　　要：目的　评价早期预防性全视网膜光凝治疗缺血型视网膜静脉阻塞的有效性和安全性。方法　用氩离子激光器 ,对病史短于 3个月的缺血型视网膜静脉阻塞 2 1例 2 1眼 ,行全视网膜光凝 ,10 0 0～ 2 0 0 0个光凝点 (平均15 0 7点 )分 3～ 5次完成。观察光凝前后眼部新生血管的消退和视力变化情况 ,以及远期并发症的发生情况。结果　随访 3个月至 2年 ,平均 18 4个月。无一例发生虹膜新生血管和新生血管性青光眼 ;发生玻璃体出血 2例 ;治疗后视力与治疗前比较差异无显著意义 (P >0 0 5 )。结论　早期全视网膜光凝预防和减少由缺血型视网膜静脉阻塞引起的并发症是有效的 。Objective To evaluate the safety and efficacy of treating ischemic central retinal vein occlusion (CRVO) with early prophylactic panretinal photocoagulation(PRP). Methods Twenty one eyes of 21 cases suffered from ischemic CRVO with history shorter than 3 months were included in this study. PRP treatments were completed through 3 to 5 times of laser therapy with total laser burns of 1000 to 2000(mean 1507). Patients were followed up for 3 months to 2 years, mean 18 4 months. The neovascularization regression and visual acuity were compared before and after PRP, also the long term complications were evaluated. Results There was no significant difference in visual acuity between prelaser and postlaser treatment. No iris neovacularization(INV) and neovascular glaucoma(NVG) occurred but vitreous hemorrhage occurred in 2 eyes during the follow up period. Conclusions Early panretinal photocoagulation is safe and efficacious in preventing and reducing complications of ischemic CRVO. It may save valuable treatment time for some patients
