氪离子激光光凝治疗糖尿病视网膜病变疗效观察

摘要

目的 观察氪离子激光治疗糖尿病视网膜病变(DR)的效果.方法 荧光素眼底血管造影(FFA)确诊为Ⅲ～Ⅴ期DR96例(184只眼),术前查视力、裂隙灯、眼底和FFA,根据病变部位、性质、屈光介质情况选择不同波长激光进行全视网膜光凝(PRP),术后随访6～36个月.结果 治疗后184只眼视力提高60只眼,占32.61％；视力无变化90只眼,占48.91％；视力下降34只眼,占18.48％.结论 氪离子激光治疗可提高或保护DR患者的视功能.%Objective To observe the effects of krypton lasers on diabetic retinopathy. Methods 96 cases (184 eyes) of diabetic retinopathy in the stages of Ⅲ - Ⅴ were reviewed and identified by fundus fluorescein angiography (FFA). The visual acuity, slit-lamp, ophthalmoscopy and fundus fluorescein angiography were performed preoperatively. They were treated with krypton lasers paneretinal photocoagulation, according to the characteristics and the different manifestations of the affected eyes. The follow-up period was 6-36 months. Results Visual acuity improved in 60 eyes (32.61% ), remained with no changes in 90 eyes (48.91% ), and decreased in 34 eyes (18.48% ). Conclusion The krypton lasers is a safe and effective approach in treating diabetic retinopathy. It can improve or retain patients vision.
