Abstract

The modern standard of treatment of clinically significant diabetic macular edema is macular laser photocoagulation was suggested in the reports of the Early Treatment of Diabetic Retinopathy Study (ETDRS, 1985-1990). Subthreshold microphotocoagulation (MicroPulase) leads to developing barely visible or invisible retinal burns and also has been shown to be effective in treating macular edema with no side effects comparing with ETDRS methodic (retinal pigment and choroidal atrophy, decreasing of retinal sensitivity). Effectiveness of microphotocoagulation may arise in high density laser applications, however in modern literature exists rare publications concerning this question.
