对增殖性糖尿病视网膜病变（Ｐｒｏｌｉｆｅｒａｔｉｖｅｄｉａｂｅｔｉｃｒｅｔｉｎｏｐａｔｈｙ，ＰＤＲ）患者２７０例３６３眼氩激光视网膜光凝疗效进行分析。光凝后新中血管消退、未再玻璃体出血者占６３．６％，其中视网膜新生血管与视盘新生血管、视网膜新生血管合并视盘新生血管间疗效差异均非常显著（Ｐ＜０．０１）：单纯新生血管与新生血管合并玻璃体出血者间疗效差异非常显著（Ｐ／０．０１），表明氩激光视网膜光凝治疗增殖性糖尿病视网膜病变的疗效与新生血管的存在部位及是否合并玻璃体出血有关。
270 patients with proliferative diabetic retinopathy (Proliferative diabetic retinopathy, 270 cases of argon laser retinal photocoagulation efficacy analysis. After photocoagulation, the new blood vessels subsided and no further vitreous hemorrhage accounted for 63.6%. There were significant differences in the therapeutic effect between retinal neovascularization and optic disc neovascularization and retinal neovascularization with optic disc neovascularization (P <0.01) The difference of curative effect between neovascular and neovascular vessel with vitreous hemorrhage was very significant (P / 0.01), which indicated that the curative effect of argon laser photocoagulation on proliferative diabetic retinopathy was related to the existence of neovascularization and the combined vitreous hemorrhage.
