Vitrectomy with BP and iOCT-assisted ILM peeling using the inverted ILM flap technique in patients with large FTMH is a very controlled and safe microsurgical strategy and shows good functional and anatomical results. The morphology of the FTMH, the ILM flap and the position of the inverted ILM flap under air was well visualized by IOCT. The microstructural integrity of the outer retinal layers is displayed in detail on SD-OCT and represents an important predictive parameter for BCVA after macular hole surgery.

To date, iOCT is only available in standing microscopes with no measurement or tracking features. Moreover, metal instruments currently obscure the scanned images. In the future, non-metal, transparent instruments (OCT-friendly surgical tools), tracking features, an autofocus and higher resolution could enable full and immediate intraoperative SD-OCT diagnostics in real time.

Intraoperative iSD-OCT is highly useful as an additional intraoperative diagnostic tool in patients with vitreous haemorrhage. In addition to the en face microscope image, it facilitates intraoperative real-time diagnosis and aids therapeutic decision-making during surgery.
