摘　　要：目的:探讨糖尿病视网膜病变(diabetic retinopathy,DR)不同分期的患者视网膜激光治疗的视力预后。方法:根据糖尿病性视网膜病变视网膜光凝研究组(Diabetic Retinopathy Photocoagulation Study Group,DRPS)治疗技术规定,将138例(210眼)分别为非增殖期糖尿病视网膜病变(nonproliferativedia-beticretinopathy,NPDR)、增殖前期糖尿病视网膜病变(preproliferative diabetic retinopathy,PPDR)、增殖期糖尿病视网膜病变(proliferative diabetic retinopathy,PDR)的患者行视网膜激光光凝治疗,术后3～6个月监测视力变化,并行眼底荧光血管造影(fundus fluorescence angiography,FFA)检查,观察荧光素渗漏、毛细血管无灌注区、微血管瘤及新生血管等有无消退,酌情补充光凝。随访6～24个月。结果:经过激光光凝治疗后NPDR期视力提高和不变占95.83%,PPDR期视力提高和不变占91.67%,PDR期视力提高和不变占73.81%。3～6月后复查FFA显示,NPDR期有效占95.83%,PPDR期有效占78.33%,PDR期有效占60.31%。结论:DR的不同分期行视网膜激光光凝治疗后视力预后不同,因此,选择合适的时机和合理的激光参数对不同分期DR尤其是伴有黄斑水肿的DR患者进行视网膜激光光凝治疗,是挽救其视功能的关键。Objective To assess the visual prognosis of laser treament for diabetic retinopathy at different stages.Methods Based on the Diabetic Retinopathy Photocoagulation Study Group(DRPS),138 patients(210 eyes) with nonproliferative diabetic retinopathy(NPDR),preprolife-rative diabeticretinopathy(PPDR),or proliferative diabetic retinopathy(PDR) were treated with laser photocoagulation.After 3 to 6 months,visual changes were inspected,fundus fluorescence angiography(FFA) was performed.Further photocoagulation was c...
