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 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.
