After review of literature about diagnosis and treatment of diabetic macular edema own results with mean observation time of 5 months are presented. After photocoagulation the visual acuity improved in eyes with focal maculopathy in 28.9%, stabilized in 62.2% and in 8.9% it was worse. In eyes with diffuse maculopathy improvement was observed in 29.6%, stabilisation only in 37%, deterioration in 33.3%. In ischemic maculopathy the visual acuity improved in 23%, stabilised in 76.9% and in none case deterioration was stated. We plan to reevaluate our results during longer observation time.
