[Intraoperative Optical Coherence Tomography in Vitreoretinal Surgery: Clinical Experiences and Future Developments].

Purpose: High resolution optical coherence tomography (OCT) enables better visualization of ophthalmic microstructures than conventional imaging. When using an ophthalmic microscope, integrated optical coherence tomography (iOCT) high resolution real time visualization is possible.
Methods: We report on the first 110 patients operated on using a microscope integrated OCT (iOCT) during surgical procedures for the treatment of various posterior segment pathologies.
Results: Microstructural changes that appeared during surgery were depicted precisely by iOCT, and the morphology visualized before and after each surgical step was used to help deciding how to adapt the surgical flow. The iOCT data and real-time imaging of retinal anatomy gives the surgeon the possibility of deploying patient- and operation-specific interventional procedures.
Discussion: 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.
