Time course of eccentric macular hole formation after pars plana vitrectomy for epiretinal membrane detected by optical coherence tomography
Abstract
Purpose: This case report aims to describe the detailed time course of eccentric macular hole (MH) formation following pars plana vitrectomy (PPV) for epiretinal membrane (ERM) treatment, using optical coherence tomography (OCT) images. Observations: A 60-year-old male patient presented to our hospital with complaints of blurred vision and distortion in his left eye. He was diagnosed with an ERM in the affected eye and subsequently underwent PPV with internal limiting membrane peeling. The patient's initial postoperative course was unremarkable; however, one month later, macular edema worsened, as evidenced by OCT findings. Initially, the edema was observed in both nasal and temporal to the fovea. However, four months postoperatively, the retina fluid in the area nasal to the fovea resolved, and the resolution was delayed in the area temporal to the fovea. At 18 months postoperatively, an eccentric macular hole was detected in the temporal to the fovea. The patient remained asymptomatic, and at the two-year follow-up, the eccentric macular hole demonstrated no signs of enlargement. Conclusions and Importance: This case demonstrates the progression of an unusual asymptomatic parafoveal full-thickness retinal hole after PPV for ERM treatment. Since the development of this condition may occur over a more extended postoperative period than previously reported, long-term patient monitoring is essential following ERM or MH surgery.
