PURPOSE: The aim of this study was to investigate the efficacy and safety of intravitreal dexamethasone implant for the treatment of macular edema after pars plana vitrectomy (PPV) for epiretinal membrane (ERM) removal. METHODS: This prospective study included 27 patients who were diagnosed with macular edema after PPV for ERM removal and who were treated with either intravitreal dexamethasone implant (n = 15) or were observed without intervention (n = 12). Changes in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were assessed 1, 6, and 12 months -after treatment. RESULTS: Patients treated with intravitreal dexamethasone implant showed significant improvement in BCVA and reduction in CRT at months 1, 6, and 12 after treatment, while patients in the control group showed improvement that did not reach statistical significance. The two groups differed significantly in terms of BCVA and CRT at all time points of the follow-up period, in favor of the dexamethasone implant group. Eighty percent of the patients treated with intravitreal dexamethasone needed only one implant until month 12, while no serious adverse events were noticed in any group. CONCLUSIONS: Intravitreal dexamethasone implant was found to be effective and safe for the treatment of macular edema after PPV for ERM removal.
