Brief Summary

Epiretinal membrane (ERM) is a commonly encountered vitreoretinal interface anomaly with a prevalence of approximately 10% in the adult population. It is often treated with pars plana vitrectomy (PPV) and membrane peeling when symptomatic. PPV is generally successful at improving visual acuity (VA) and/or metamorphopsia. At times, however, visual recovery can be hindered by macular edema in the post-vitrectomy period. Ozurdex can accelerate the resorption of intraretinal edema and hasten the improvement in the visual acuity. It has been shown to facilitate fluid absorption by both stimulating endogenous adenosine signaling in Muller cells and by down regulating vascular endothelial growth factor production. So, this study aim to investigate the efficacy of Ozurdex implant after PPV in epiretinal membrane eyes.
