目的：探讨激光光凝治疗非增殖性糖尿病视网膜病变黄斑水肿的方法和疗效。方法：回顾性分析我院１５０例（２２５只眼）糖尿病视网膜病变黄斑水肿，全部病例行眼底荧光血管造影，将其分为局部性和弥漫性黄斑水肿，分别采用局灶性光凝和栅格状光凝。４５例（６０只眼）糖尿病视网膜病变黄斑水肿，不用激光光凝，作为对照组。随访１～３年，分析其视力和黄斑水肿的变化。结果：２２５只眼中，１４５只眼为局部性黄斑水肿，８０只眼为弥漫性黄斑水肿。光凝术后，视力提高２行以上者８０只眼，占３５．５％；稳定不变者１２３只眼，占５４．７％；下降２行以上者２２只眼，占９．８％。而对照组视力提高２行以上者仅２只眼，占３．３％；视力下降２行以上者２４只眼，占４０．０％；两组疗效比较差异有非常显著性（Ｐ＜０．０１）。光凝组中，局部性黄斑水肿视力提高率高于弥漫性黄斑水肿，两组比较差异有显著性（Ｐ＜０．０５）。结论：激光光凝治疗非增殖性糖尿病视网膜病变黄斑水肿效果肯定，且早期治疗效果好。
Objective: To investigate the method and efficacy of laser photocoagulation in the treatment of macular edema of non-proliferative diabetic retinopathy. Methods: A retrospective analysis of 150 cases of our hospital (225 eyes) diabetic retinopathy macular edema, all cases of fundus fluorescein angiography, divided into local and diffuse macular edema, respectively, by focal photocoagulation and grid Photocoagulation. 45 cases (60 eyes) diabetic retinopathy macular edema, without laser photocoagulation, as a control group. Follow-up 1-3 years, analysis of visual acuity and macular edema changes. RESULTS: Of the 225 eyes, 145 eyes had localized macular edema and 80 eyes had diffuse macular edema. After photocoagulation, the visual acuity of 80 eyes increased by more than 2 lines, accounting for 35.5%; 123 eyes of stable change, accounting for 54.7%; 22 eyes decreased by more than 2 lines, accounting for 9.8%. While in the control group, the visual acuity increased by 2 lines or more, only 2 eyes, accounting for 3.3%. The visual acuity decreased by 2 lines or more, 24 eyes, accounting for 40.0%. There was significant difference between the two groups (P <0. 01). In the photocoagulation group, the rate of improvement of visual acuity of local macular edema was higher than that of diffuse macular edema. There was significant difference between the two groups (P <0.05). Conclusion: Laser photocoagulation treatment of non-proliferative diabetic retinopathy macular edema affirmation, and the early treatment effect is good.
