Abstract
PURPOSE: To determine the efficacy of internal limiting membrane (ILM) peeling during vitrectomy for rhegmatogenous retinal detachment (RRD) regarding post-vitrectomy epiretinal membrane (ERM) development and visual outcomes. DESIGN: Retrospective, interventional, comparative case series. METHODS: Setting: Institutional. STUDY POPULATION: One hundred and two consecutive eyes with RRD treated with vitrectomy and followed for at least 6 months. ILM was peeled without using dye such as indocyanine green (ICG). Observational Procedures: Patients were divided into 2 groups based on postoperative ERM development: Group 1, 81 eyes without ERM formation; Group 2, 21 eyes with ERM development. Patients also were divided into 2 subgroups: those with and without ILM peeling (58 and 44 eyes, respectively). Statistical analyses were performed between the 2 groups with/without ERM formation and between the 2 subgroups with/without ILM peeling for 5 preoperative factors including foveal involvement of the RRD, 4 intraoperative factors including ILM peeling, baseline best-corrected visual acuity (BCVA), and final BCVA. MAIN OUTCOME MEASURES: An association of ILM peeling with ERM prevention and the influence of ILM peeling on visual outcomes. RESULTS: ILM peeling was significantly (P < .001) associated with ERM prevention. There was no significant difference in the final BCVA between subgroups with and without ILM peeling. CONCLUSIONS: ILM peeling without ICG staining during the initial vitrectomy for RRDs may prevent postoperative ERM formation with favorable visual outcomes.
