MACULAR HOLE FORMATION IDENTIFIED WITH INTRAOPERATIVE OCT DURING VITRECTOMY FOR VITREOMACULAR TRACTION SYNDROME

To report the identification of macular hole formation using intraoperative optical coherence tomography (OCT) during vitrectomy for vitreomacular traction syndrome.

A 58-year-old woman with vitreomacular traction syndrome underwent the vitrectomy using the 25-gauge system with scanning the macular area using the integrated and intraoperative OCT (Rescan 700, Zeiss). When posterior vitreous detachment at the fovea was performed using a vitreous cutter, the hyperreflective tissue thought to be the rupture of the internal limiting membrane and the full-thickness macular hole were identified on the horizontal and vertical scans simultaneously in intraoperative OCT.

The procedure was completed after internal limiting membrane peeling and 25% SF6 gas tamponade for closure of macular hole. The closure was confirmed using Swept-Source OCT 1-month after surgery.

It is possible to change the surgical approach using the real-time intraoperative OCT because the development of macular hole can be visualized during vitrectomy for vitreomacular traction syndrome.
