Abstract
Purpose: To study the incidence, morphology, and factors affecting macular edema after pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD). Study design: Retrospective study. Materials and methods: The study was conducted at a single institution over a period of 1 year. Adults who underwent PPV and silicone oil injection for the repair of primary RRD were included in the study. The main outcome measure was the incidence of macular edema at 3 months post surgery. Results: A total of 45 eyes were included. The incidence of macular edema was found to be 26.66% (12 out of 45), with the most common type being spongiform. Patients with advanced proliferative vitreoretinopathy (PVR) changes at presentation were significantly more prone to develop macular edema (P = 0.007). However, internal limiting membrane peel, duration of RRD, pseudophakia, and macula status were not found to be significant risk factors. Five patients with increased central retinal thickness on optical coherence tomography were given posterior subtenon triamcinolone injections. Conclusion: Macular edema is a relatively common complication after PPV, with an incidence of 26.66% in our study, which can result in suboptimal visual gain. Severe PVR was found to be a significant risk factor for macular edema.
