目的:观察577 nm多点扫描距阵激光治疗糖尿病性黄斑水肿(DME)的疗效.方法:回顾性分析接受577nm多点扫描距阵激光黄斑区格栅样光凝联合全视网膜光凝治疗的DME患者26例(32只眼).光凝分3～4次、成,随访3个月.治疗前及治疗后1周、1、3个月均进行最佳矫正视力( BCVA)、眼底及光学相干断层扫描(OCT)检查.光凝前及光凝后3个月行眼底荧光血管造影检查(FFA).对比分析治疗前后患者BCVA和黄斑中心视网膜厚度(CMT)的变化.结果:26例(32只眼)光凝术前与光凝术后3个月BCVA比较,差异有统计学意义(x2=6.078,P＜0.05).患者光凝术前、术后1周、术后1个月、术后3个月的CMT差异具有统计学意义(F=13.657,P＜0.05).结论:577 nm多点扫描距阵激光可以有效地减轻DME,治疗操作简单,对控制和延缓患者病情发展,稳定患者视力有重要意义.%Objective: To investigate the effects of retinal photocoagulalion wilh 577 nm supra scan laser on diabetic macular edema (DME ). Methods: 26 cases (32 eyes) with DME were treated with grid photocoagulation at macular area and panretinal photocoagulation by 577 nm supra scan laser. The treatment was completed in 3-4 sessions, and the follow-up period was 3 months. Before treatment and 1 week, 1 and 3 months after treatment, the best corrected visual acuity ( BCVA ), ophthalmoscopy and central macular thickness (CMT) with optical coherence tomography (OCT) were measured. 3 months after treatment fluorescein fundus angiography (FFA) were performed. The changes of BCVA and CMT of all the 32 eyes were evaluated before and after the treatment. Results: The BCVA before treatment and 3 months after treatment, showed a statistically significant between them (Xi=6.078, P<0.05). The mean CMT before treatment, 1 week, 1 month and 3 months after treatment, showed a statistically significant difference among them( F= 13.657, P<0.05). Conclusion: Photocoagulation with 577nm supra scan laser is a simple and effective therapy for DME, and it can control DME and maintain visual acuity.
