Since its first introduction more than 30 years ago, optical coherence tomography (OCT) has revolutionized ophthalmology practice, providing a non-invasive in vivo cross-sectional view of the structures of the eye. Mostly employed in the clinical setting due to its tabletop configuration requiring an upright patient positioning, the recent advent of microscope-integrated systems now allows ophthalmologists to perform real-time intraoperative OCT (iOCT) during vitreoretinal surgical procedures. Numerous studies described various applications of this tool, such as offering surgeons feedback on tissue-instrument interactions in membrane peeling, providing structural images in macular hole repair, and showing residual subretinal fluid or perfluorocarbon in retinal detachment surgery. This narrative review aims at describing the state of the art of iOCT in vitreoretinal procedures, highlighting its modern role and applications in posterior segment surgery, its current limitations, and the future perspectives that may improve the widespread adoption of this technology.
自 30 多年前首次引入以来，光学相干断层扫描（OCT）彻底改变了眼科实践，为眼睛结构提供了非侵入性的体内横截面视图。由于其台式配置需要患者保持直立姿势，因此主要在临床环境中使用，最近出现的显微镜集成系统现在允许眼科医生在玻璃体视网膜手术过程中进行实时术中 OCT（iOCT）。许多研究描述了该工具的各种应用，例如为外科医生提供在膜剥离过程中组织与器械相互作用的反馈，在黄斑裂孔修复中提供结构图像，并显示视网膜脱离手术中的残余视网膜下液或全氟碳。本叙述性综述旨在描述 iOCT 在玻璃体视网膜手术中的最新技术状态，突出其在后部段手术中的现代作用和应用，当前的局限性以及可能改善该技术广泛应用的未来前景。
