Purpose To test a combination of dexamethasone intravitreal implant with macular grid laser for macular edema in patients with branch retinal vein occlusion (BRVO). Design Prospective interventional, randomized, multicenter study. Methods Patients with macular edema secondary to BRVO underwent an Ozurdex intravitreal implant at baseline. After 1 month, patients were randomly assigned to 2 study groups. Patients in Group 1 were followed up monthly and retreated with Ozurdex implant whenever there was a recurrence of macular edema or a decrease in best-corrected visual acuity (BCVA). In Group 2 patients macular grid laser was performed between weeks 6 and 8. After that, patients were followed up and retreated as for Group 1. Results In Group 1 at 4 months, mean BCVA was 0.49 ± 0.35 logMAR and central retinal thickness (CRT) was 391 ± 172 μm; both improved significantly at 6 months, to 0.32 ± 0.29 logMAR and 322 ± 160 μm, respectively. In Group 2, CRT was reduced significantly to 291 ± 76 μm at 4 months, and BCVA improved to 0.25 ± 0.20 logMAR. At the final visit, BCVA was 0.18 ± 0.14 logMAR and mean CRT was 271 ± 44 μm. The number of Ozurdex implants at 4 months was 12 of 25 (48%) in Group 1 patients vs 3 of 25 (12%) in Group 2 patients (P =.012). At 6 months 3 of 25 patients (12%) in Group 1 vs 0 of 25 (0%) in Group 2 (P =.23) were retreated. Conclusions The combination of Ozurdex implant and macular grid laser is synergistic in increasing BCVA and lengthening the time between injections.
