Double flaps of internal limiting membrane for chronic optic pit maculopathy with large outer lamellar hole

Abstract

A 24-year-old woman presented with very chronic optic pit maculopathy and outer lamellar hole. During vitrectomy, two internal limiting membrane (ILM) flaps were designed and inverted from the temporal to the nasal side to cover the thin-roofed fovea and the optic pit. Two weeks post vitrectomy, the outer lamellar hole de-roofed into a full-thickness macular hole but remained covered with the inverted ILM flap. The hole edges grew centripetally and re-bridged over the next month. By 9 months, the macular hole had closed, schisis settled, and BCVA improved substantially.
