目的探讨激光治疗白内障术后糖尿病视网膜病变疗效。方法将120例单眼白内障合并双眼糖尿病视网膜病变的患者分为治疗组、对照组,对术前及术后眼底情况进行观察。并于术前或术后早期行视网膜激光光凝治疗。结果对照组68只眼,进展25只眼,稳定43只眼,治疗组52只眼,进展10只眼,稳定42只眼(χ2=4.39,P<0.05)。两组对侧眼共120只眼,进展30只眼,稳定90只眼(χ2=5.01,P<0.05)。结论白内障手术可加速糖尿病视网膜病变进展。术前或术后尽早行全视网膜激光光凝术可有效阻止病变进展。
Objective To investigate the therapeutic effect of laser on diabetic retinopathy after cataract surgery. Methods One hundred and twenty cases of monocular cataract with binocular diabetic retinopathy were divided into treatment group and control group. Preoperative and postoperative fundus cases were observed. And preoperative or postoperative retinal laser photocoagulation. Results The control group, 68 eyes, 25 eyes progressed, stable 43 eyes, the treatment group 52 eyes, progress 10 eyes, stable 42 eyes (χ2 = 4.39, P <0.05). A total of 120 eyes of the contralateral eye in both groups, 30 eyes of progress, stable 90 eyes (χ2 = 5.01, P <0.05). Conclusion Cataract surgery can accelerate the progress of diabetic retinopathy. Preoperative or postoperative retina laser photocoagulation can effectively prevent the progression of the disease.
