氩激光治疗糖尿病视网膜病变的疗效分析

目的观察氩激光治疗糖尿病视网膜病变（DR）的效果。方法选择经眼底血管荧光造影（FFA）确诊为重度非增生性DR患者36例（68眼），然后根据FFA结果行标准的全视网膜光凝（PRP），其中合并有临床意义黄斑水肿的56眼同时进行局部格栅样光凝治疗。治疗后2—24个月分别行FFA检查，对需要者进一步补充光凝。随诊观察至光凝治疗后2年，对光凝治疗前后的视力、视网膜病变进展程度（通过FFA和眼底照相）进行评价。结果本组病例在接受光凝治疗后2年内，视力变化差异有统计学意义（P=0．021），以光凝后2年的视力变化最为显著。但视力〉0．3者的比例变化不大，在光凝前为41．3％，光凝后1年、2年分别为42．1％，39．8％。黄斑水肿通过局部光凝治疗2年内视力稳定或改善的患者达到72．1％。光凝术后1年、2年视网膜病变稳定。结论对重度非增生性DR患者进行氩激光治疗，对合并黄斑水肿的患者同时进行黄斑区格栅样光凝，可使多数患者DR病情稳定，延缓进展。

Effect of argon laser photocoagulation for diabetic retinopathy

Objective To probe the effect of argon laser photocoagulation for diabetic retinopathy. Methods A total of 36 patients with 68 eyes of diabetic retinopathy diagnosed by fundus fluoreseein angiography （FFA） were treated by argon laser with standard panretinal photoeoagulation, among the total, Grid photoeoagulation was performed on 56 eyes with clinical significant maeular edema. During the follow-up period of 2 -24 months, FFA was carried out and cases requiring supplement were complemented with further photocoagulation. The results of visual acuity and FFA were analyzed. Results 2 years after treatment, visual acuity was improved. The proportion of visual acuity（ 〉 0. 3） was 41.3% before treatment, and 1 year and 2 years after treatment the number was 42. 1% and 39.8% respectively. 72. 1% vision improved Or remainde unchanged in 2 years after grid photocoagnlation in eases with clinical significant macular edema. The retinopathy remained stable after 1 year and 2 years. Conclusion The argon panretinal photocoagulation, combined with grid photocoagulation on eyes with clinical significant macular edema can maintained stable in treating diabetic retinopathy, and with few complications.
