PPV for ERM and MH was performed by vitreoretinal fellows and consultants.Results: The outcome measures assessed were the intraoperative complications rates, such as posterior lens touch, retinal breaks (RBs), retinal detachments, and vitreous hemorrhage. Moreover, the postoperative complications and optical coherence tomography (OCT) changes were assessed upon a minimum follow-up of 6 months. The rate of iatrogenic RB was more common in the ERM than in the MH surgery (15.5% vs 11.2%). Fellows and consultants had a rate of 20.5% of RB during the ERM surgery and 14.6% during MH surgery, respectively. However, these differences were not statistically significant (p = 0.12 for MH and p = 0.236 for ERM). Postoperative OCT analysis revealed an MH closure rate of 72.2%, and complete removal of the ERM was achieved in 88.6% in cases performed by fellows, while consultants achieved 61.8% closure rate of MH, and 83.3% of the patients achieved complete removal of ERM.Conclusion: Macular surgery is overall a safe procedure and the complication rates between fellows and consultants are comparable. With proper supervision, vitreoretinal fellows can achieve equally high anatomical outcomes with few complications.Keywords: epiretinal membrane, fellows, macular hole, pars plana vitrectomy, retinal break
