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.
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.
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.
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.
与传统成像相比，高分辨率光学相干断层扫描（OCT）能够更好地显示眼部微观结构。使用眼科显微镜时，集成光学相干断层扫描（iOCT）可实现高分辨率实时可视化。
我们报告了首批110例在手术过程中使用显微镜集成OCT（iOCT）治疗各种后段病变的患者情况。
iOCT精确描绘了手术过程中出现的微观结构变化，每个手术步骤前后可视化的形态用于帮助确定如何调整手术流程。iOCT数据和视网膜解剖结构的实时成像使外科医生有可能开展针对患者和手术的特定介入程序。
迄今为止，iOCT仅在没有测量或跟踪功能的立式显微镜中可用。此外，金属器械目前会遮挡扫描图像。未来，非金属、透明器械（对OCT友好的手术工具）、跟踪功能、自动对焦和更高分辨率可实现术中实时、全面的SD-OCT诊断。
