半导体532激光治疗糖尿病视网膜病变的临床观察

目的：观察半导体532激光光凝术治疗糖尿病视网膜病变（ DR）的临床疗效。方法采用半导体532激光对50例（95只眼）非增殖性和增殖性DR患者进行局限性视网膜光凝、格栅样视网膜光凝或全视网膜光凝治疗。观察治疗前后视力、裂隙灯、眼底、眼压、眼底血管荧光造影及眼底OCT的变化，光凝术后随访6个月。结果光凝术后36眼（37．9％）视力提高，视力无变化52眼（54．7％），视力下降7眼（7．4％），总有效88眼（92．6％）。伴黄斑水肿者26眼，经光凝后黄斑水肿完全或部分消退，未出现新的黄斑水肿。结论半导体532激光光凝术治疗DR安全有效。

Photocoagulation with 532 semiconductor laser in the treatment of diabetic retinopathy

Objective To observe the photocoagulation treatment effect of using 532 semiconductor laser in the treatment of diabetic retinopathy .Methods A total of 50 cases（95 eyes） of nonproliferative and proliferative dia＆amp;nbsp;betic retinopathy received local retinal photocoagulation ,grid photocoagulation or panretinal photocoagulation treatment carried out by 532 semiconductor laser .We observed visual acuity ,slit lamp biomicroscopy ,intraocular pressure ,oph-thalmoscopy,fundus fluorescence angiography （FFA） and optical coherence tomography （OCT）.These patients were followed up for 6 months after laser treatment .Results Among the 95 eyes,visual acuity was improved in 36 eyes （37.9%）,unchanged in 52 eyes（54.7%） and decreased in 7 eyes（7.4%）.Among the 26 eyes with clinical signifi-cant macular edema （ CSME ） , macular edema was resolved completely or partly resolved after photocoagulation . Conclusion Photocoagulation with 532 semiconductor laser in the treatment of diabetic retinopathy was safe and ef-fective.
