Purpose: To investigate the incidence of macular edema after pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) repair, the factors affecting its development and the efficacy of intravitreal dexamethasone implant for its treatment. Methods: Participants in this study 86 patients with RRD. All patients were examined postoperatively and those with macular edema were treated with intravitreal dexamethasone implant and were followed-up for 12 months. Results: 14 out of 86 patients presented macular edema post PPV for RRD repair. Patients with preoperative macula off RRD, duration of RRD >1 week and proliferative vitreoretinopathy were more prone to develop macular edema. There was a statistically significant improvement in best corrected visual acuity and central retinal thickness at month 12 post intravitreal dexamethasone implant compared to baseline.Conclusions: The incidence of macular edema post PPV for RRD repair was found to be 16.3%. Intravitreal dexamethasone implant seemed to be safe and effective in cases with post-PPV macular edema after RRD repair.
