Eccentric Macular Hole after Pars Plana Vitrectomy for Idiopathic Macular Hole: A Case Report.

Introduction: Postoperative eccentric macular hole (MH) formation is an uncommon complication after pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling for epiretinal membrane or MH treatment. Herein, we present a case of eccentric MH formation after PPV with ILM peeling for MH.

Case Description: A 72-year-old female patient underwent 23-gauge PPV with ILM peeling for idiopathic MH in her right eye. The visual acuity was 6/24 in the right eye. One week postoperatively the retina was attached and the MH seemed to be closed, while visual acuity was 6/12. One month after PPV, there was a single eccentric retinal hole below the macula, which was detected at the fundoscopy and was confirmed by OCT. The visual acuity was 6/9 and the patient referred no symptoms. No further intervention was attempted, and at the 6-month follow-up the visual acuity and the size of the eccentric MH remained stable.

Conclusions: Eccentric MHs can develop after PPV and are usually managed conservatively by observation.
