氩激光治疗增殖型糖尿病视网膜病变60例疗效观察

A clinical study of treatment with argon laser in 60 cases of proliferative diabetic retinopathy

目的探讨氩激光治疗糖尿病视网膜病变的疗效。方法对60例101只眼增殖性糖尿病视网膜病变氩激光治疗,对增殖前期病变行次全视网膜光凝,增殖期病变行全视网膜光凝,治疗后3～6个月做眼底荧光造影检查,判断视网膜无灌注区及新生血管的消退情况。结果光凝治疗前后视力变化无统计学意义(P均(0.05),随访3～6个月后复查眼底荧光造影显示视盘及视网膜新生血管部分或全部消退。结论增殖期及增殖前期糖尿病视网膜病变,早发现早治疗,根据不同的病例选择不同的视网膜光凝,可以保存患者的有用视力,有效预防并发症,氩激光治疗对糖尿病视网膜病变是行之有效的。

Objective：To evaluate the therapeutic effect of argon laser in diabetic retinopathy.Methods： The treatment with argon laser was given in 60 cases（101 eyes） of proliferative diabetic,of which those with pre-proliferative diabetic retinopathy were treated by light panretinal photocoagulation.The others who surfered from proliferative diabetic retinopathy were treated by panretinal photocoagulation.Then,fundus fluorescein angiography was used to access the regression of capillary non-perfusion zone and neovascularization after 3-6 months.Results： There were no significant changes of visual betweeen before and after retinal photocoagulation（P﹥0.05）.After 3-6 months＇following up visit,fundus fluorescein angiongraphy was given and it was found that there were 84 eyes（83.16%） which neovascularization in disc and retinal disappeared partly or completely,and capillary non-perfusion zone regressed partly or completely.Five eyes＇iris neovascularization regressed and pressure decreased after panretinal photocoagulation.Conclusion： If early detection and treatment are done,different retinal photocoagulation ia given according to different cases,the patients who suffered from pro-proliferative and proliferative diabetic retinopathy can preserve their left VA and prevent complications.It suggests that the argon laser treatment is an effective method for diabetic retinopathy.
