Abstract

Persistent macular edema (ME) after surgical removal of epiretinal membrane (ERM) may impair postoperative visual recovery. Sustained-release dexamethasone intravitreal implant (DEX) was used to treat recalcitrant ME after vitrectomy for ERM. Retrospective chart review of eyes treated with DEX for ME after ERM removal. Visual and anatomic outcomes were evaluated. Five eyes with refractory ME on optical coherence tomography (OCT) after ERM surgery were treated with DEX. Four of five eyes demonstrated reduction in macular thickness on OCT (mean: 106 μm), with mean percentage reduction in central foveal thickness of 25%. Visual acuity improved by one or more Snellen lines in four of five eyes. DEX effect duration was 3 to 9 months. Two eyes with OCT and visual improvement after initial DEX received multiple DEX implants for maintenance therapy. Inflammatory factors may contribute to persistent ME after vitrectomy for ERM. DEX may be a treatment option in such cases.
