Risk Factors for Macular Hole Development After Pars Plana Vitrectomy for Rhegmatogenous Retinal Detachment.

To identify intraoperative and postoperative risk factors for macular hole (MH) formation after prior pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) repair. This retrospective case-control study compared eyes that developed MH after PPV for RRD (cases) and those that underwent PPV for RRD without forming MH (controls). Cases were matched to controls using propensity scores based on demographic, preoperative, and RRD characteristics.
