Purpose: The aim of the present study was to investigate the effect of subthreshold diode laser micropulse in comparison with conventional laserphotocoagulation in the treatment of the diabetic macular edema.Methods: Sixty-eight eyes from 68 patients with clinically significant diabetic macular edema were divided randomly into two equal groups. Inthe first group, subthreshold diode laser micropulse photocoagulation was employed, while conventional laser photocoagulation was performedon the eyes of the second group. Central macular thickness, central macular volume, and best corrected visual acuity were measured before, 2,and 4 months after intervention, and the results were compared.Results: The mean central macular thickness was 357.3 and 354.8 microns before the treatment in Groups 1 and 2, respectively (P ¼ 0.85), anddecreased significantly to 344.3 and 349.8 after 4 months, respectively (P ¼ 0.012 and P ¼ 0.049). The changes in the central macular thicknesswas statistically higher in the first group (P ¼ 0.001). The mean central macular volume significantly decreased in Group 1 (P ¼ 0.003), but itwas similar to pretreatment in Group 2 after 4 months (P ¼ 0.31). The best corrected visual acuity improved significantly in Group 1 (P ˂ 0.001),but it remained unchanged in Group 2 (P ¼ 0.38).Conclusions: In this study, subthreshold diode laser micropulse was more effective than conventional laser photocoagulation in reducing centralmacular thickness and central macular volume and improving visual acuity in patients with diabetic macular edema.Copyright © 2016, Iranian Society of Ophthalmology.
