倍频532激光光凝治疗糖尿病视网膜病变的临床观察

目的观察倍频532nm激光视网膜光凝术治疗糖尿病视网膜病变（DR）的临床效果。方法用倍频532nm激光对30例（54只眼）增生前期和增生期DR患者进行全视网膜光凝治疗，伴有临床意义黄斑水肿者，先行黄斑部光凝治疗。术前行视力、眼压、裂隙灯、眼底、荧光素眼底血管造影（FFA）检查。术后定期复查，并记录视力变化及视网膜病变进展程度。光凝术后平均随访10个月。结果治疗后18只眼（33．3％）视力提高，视力无变化32只眼（59．3％），视力下降4只眼（7．4％），有效45只眼（83．3％），随病变程度加重疗效降低。经FFA检查，有临床意义黄斑水肿者16只眼，经光凝后水肿完全消退者10只眼（62．5％），部分消退者5只眼（31．3％），不变者1只眼（6．3％）。结论倍频532nm激光视网膜光凝术是治疗DR安全、有效的方法。

Photocoagulation with 532 nm frequency-doubled laser on 30 patients with diabetic retinopathy

Objective To observe the therapeutic effect of photocoagulation with 532nm frequency-doubled laser on diabetic retinopathy(DR).Methods A total of 30 consecutive cases (54 eyes) of pre-proliferative and proliferative DR had been treated by panretinophotocoagulation with 532 nm frequency-doubled laser. We observed for visual acuity,intraocular pressure,Slit lamp biomicroscopy,direct biomicroscopy and fundus fluorescence angiography before the treatment. All cases were followed up average of 10 months.Results ...
