目的探讨氪黄激光治疗糖尿病性视网膜病变黄斑水肿的方法和疗效。方法对60例(104只眼)患有糖尿病性视网膜病变黄斑水肿选用氪黄激光进行治疗。其中非增殖期35例(65只眼),增殖期25例(39只眼),包括局灶性光凝和弥漫性格子样光凝。随访1年,观察治疗前后的视力、眼底和荧光血管造影的改变,并进行统计分析。结果光凝后视力进步者占36.5%,保持不变者占54.8%;黄斑水肿完全消退者占20.2%,部分消退者占63.5%,未消退者占16.3%。结论氪黄激光治疗糖尿病所致黄斑水肿疗效显著,且疗效于病程有关,早期治疗效果更好。
Objective To investigate the method and efficacy of krypton yellow laser treatment of macular edema of diabetic retinopathy. Methods Krypton yellow laser was used to treat 60 cases (104 eyes) of macular edema with diabetic retinopathy. Among them, 35 cases (65 eyes) were non-proliferative and 25 cases (39 eyes) were proliferative, including focal photocoagulation and diffuse lattice photocoagulation. The patients were followed up for 1 year. Visual acuity, fundus and fluorescein angiography before and after treatment were observed and analyzed statistically. Results After photocoagulation, visual acuity accounted for 36.5%, remained unchanged 54.8%; macular edema completely subsided accounted for 20.2%, part of the subsided 63.5%, not retreated 16.3%. Conclusion Krypton yellow laser treatment of diabetic macular edema caused significant effect, and the efficacy of the course of the disease, early treatment is better.
