Purpose: To report 3-year results of a randomized single-blind controlled trial of intravitreal ranibizumab combined with oral docosahexaenoic acid (DHA) supplementation versus ranibizumab alone in patients with diabetic macular edema.
Methods: There were 26 patients (31 eyes) in the DHA group and 29 (38 eyes) in the control group. Ranibizumab (0.5 mg) was administered monthly for the first 4 months followed by a pro re nata (PRN) regimen. In the experimental group, patients received oral DHA supplementation (1,050 mg/day) (Brudyretina 1.5 g).
Results: At 36 months, mean decrease of central subfield macular thickness was higher in the DHA-supplementation group than in controls (275 ± 50 mm vs. 310 ± 97 mm) with significant differences at Months 25, 30, 33, and 34. Between-group differences in bestcorrected visual acuity were not found, but the percentages of ETRDS gains .5 and .10 letters were higher in the DHA-supplementation group.
