目的：描述手持式光谱域光学相干断层扫描（SDOCT）在黄斑手术中的应用。前瞻性观察性病例系列。采用手持式SDOCT设备对黄斑病变玻璃体切除术患者进行切口前光学相干断层成像。去除内限制膜或视网膜前膜后，术中重复成像。对光谱域光学相干断层扫描结果进行表征。建立了一种获得术中SDOCT图像的有效技术。共有8名患者被纳入研究。4例为黄斑孔手术，3例为视网膜前膜手术，1例为玻璃体黄斑牵引手术。切口前和术中SDOCT图像的比较显示视网膜轮廓和黄斑孔结构的明显变化。术中SDOCT成像在两例患者中发现了额外的膜。术中使用手持式SDOCT成像为观察黄斑病变提供了一种有效的方法。在某些情况下，这项技术可能有助于确认或识别在手术中可能难以可视化的疾病。
To describe the intraoperative use of handheld spectral domain optical coherence tomography (SDOCT) imaging in macular surgery. Prospective, observational case series. A handheld SDOCT device was used to obtain preincision optical coherence tomography imaging in patients undergoing vitrectomy for macular diseases. After removal of the internal limiting membrane or the epiretinal membrane, repeat intraoperative imaging was obtained. Spectral domain optical coherence tomography findings were characterized. An efficient technique was established for obtaining intraoperative SDOCT imaging. A total of eight patients were included in the study. Four patients underwent surgery for macular hole, three patients for epiretinal membrane, and one for vitreomacular traction. Comparison of the preincision and intraoperative SDOCT images demonstrated distinct changes in retinal contour and macular hole configuration. Intraoperative SDOCT imaging identified additional membranes in two patients. The intraoperative use of handheld SDOCT imaging provides an efficient method for visualizing macular pathology. This technology may, in certain cases, help confirm or identify diseases that may be difficult to visualize during surgery.
