Randomized Clinical Trial Evaluating mETDRS versus Normal or High-Density Micropulse Photocoagulation for Diabetic Macular Edema

Abstract

At 1 year, the clinical performance of HD-SDM was superior to that of the mETDRS photocoagulation technique, according to the anatomic and functional measures of improvement used in this investigation. A rationale for this treatment modality as a preferable approach is suggested, and the precise role of subthreshold micropulse laser treatment may become more defined as experience grows, guided by optimized treatment guidelines and more comprehensive trials.
