Abstract
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.
