Surgical outcome and pathological findings in macular epiretinal membrane caused by neurofibromatosis type 2

Abstract

We present surgical outcomes in a 10-year-old Japanese girl with neurofibromatosis type 2 (NF2)–induced epiretinal membrane (ERM). Her right eye underwent lens-sparing 27-gauge microincision vitrectomy surgery (MIVS) with ERM peeling. Decimal best-corrected visual acuity increased from 0.3 to 0.4 postoperatively. However, abnormal thickening of the macula persisted for 3 years. Staining of the extracted ERM revealed many cells positive for glial fibrillary acidic protein and nestin. Although removal of NF2-induced ERM with MIVS can improve visual acuity, the potential surgical risks require careful consideration on a case-by-case basis.
