氩激光治疗增殖型糖尿病性视网膜病变

目的　观察氩激光光凝术治疗增殖型糖尿病性视网膜病变 (Proliferativediabeticretinopathy ,简称PDR)的疗效。 方法　 78眼分三组 ,增殖前期组、视网膜新生血管 (Neovasculariza tionelsewhere ,简称NVE)组、视盘新生血管 (Neovascularizationondisc ,简称NVD)组 ,行氩激光全视网膜光凝术 (黄斑区除外 ) ,观察术前、术后新生血管性病变及视力的变化 ,及光凝术后的并发症。结果　光凝术后增殖前期组 18眼 (81 8% )未发生新生血管 ,且无并发症 ;NVE组新生血管完全消退为 2 8眼 (71 8% ) ,NVD组为 7眼 (4 1 2 % ) ,两者比较差异具有显著性 (P <0 0 5 ) ;经追加光凝后仍持续存在新生血管的NVE组 6眼 (15 4% ) ,NVD组 8眼 (4 7 1% ) ,两者比较差异具有显著性 (P <0 0 5 )。各种严重并发症NVE组共 6眼 (15 4% ) ,NVD组 6眼 (3 5 2 % ) ,两者无显著性差异。三组视力术前、术后的差异无显著性。结论　氩激光全视网膜光凝术可有效阻止和治疗PDR的发展 ;对NVE的疗效优于NVD。

Effects of argon photocoagulation in proliferative diabetic retinopathy

Objective To evaluate the therapeutic effects of panretinal photocoagulation with argon laser in diabetic retinopathy.Methods 78 eyes underwent panretinal photocoagulation with argon laser and divided into 3 groups,pre-proliferative,NVE and NVD group.The changes of neovascularization and visul acuity were analyzed following the photocoagulation and observing the complications.Results After photocoagulation,18 eyes(81.8%)of pre-proliferative group had not deteriorated into PDR and no complications were observed.There were 18 eyes(71.8%)in NVE group had neovascularization eliminated and 7 eyes(41.2%)in NVD group differently( P <0.05).After additional photocoagulation,6 eyes(15.4%)in NVE had neovascularization remained and 8 eyes(47.1%)in NVD group differently( P >0.05).The severe complications were shown in 6 eyes(15.4%)of NVE and 6 eyes(35.2%)of NVD group,but no statistical signification( P >0.05)between them.No visual acuity decreased in all the 3 groups.Conclusions Panretinal photocoagulation with argon laser was effective in prevention and treatment of proliferative diabetic retinopathy.The efficacy of was better than NVD.
