Macular epiretinal membrane in high myopia: timing and prognosis of pars plana vitrectomy surgery.

Aim: To investigate the outcomes and prognosis of macular epiretinal membrane (ERM) after pars plana vitrectomy (PPV) in patients with high myopia (HM), focusing on the optimal timing of surgery and its impact on prognosis.

Methods: The clinical data of 50 eyes from 49 patients diagnosed with ERM, who were highly myopic and underwent PPV were retrospectively analyzed. The patients with ERM were classified into five groups based on the characteristics associated with different levels of myopic traction maculopathy.
