摘　　要：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。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 with 532 nm frequency-doubled laser. We observed for visual acuity, intraocular pressure, Slit lamp biomicroscopy, direct biomicroseopy and fundus fluorescence angiography before the treatment. All eases were followed up average of 10 months. Results The postoperative visual acuity improved in 18 eyes{33. 3% ）, remained unchanged in 32 eyes（ 59.3% ）, and decreased in 5 eyes（ 7.4% ）. The pre-prolifemtive stage was the best treatment opportunity, with clinical significant macular edema 16 eyes,had resolved completely in 10 eyes（62.5% ） ,partly in 5eyes（ 31.3% ） ,and was unchanged in 1 eye （6.3% ）. Conclusion Photocoagulation with 532 nm frequency-doubled laser on DR eyes was safe and effectively, especially to the pre-proliferative ones.
