Intraoperative Optical Coherence Tomography of Internal Limiting Membrane Flap

A 66-year-old woman with a 450- μm diameter macular hole (MH) in her right eye underwent vitrectomy, internal limiting membrane (ILM) peel with inverted ILM flap, and perfluoropropane (C3F8) gas tamponade. Inverted ILM flaps may improve outcomes for holes larger than 400 μm; however, confirming proper ILM placement is difficult after air-fluid exchange. Intraoperative optical coherence tomography (OCT; Zeiss, Oberkochen, Germany) was used to visualize the MH before ILM peel (Fig 1A) and confirm positioning of the inverted ILM flap (Fig 1B, arrow) following complete air-fluid exchange.
