Spectral domain optical coherence tomography (SD-OCT) is a non-invasive tool providing unprecedented imaging and analysis of vitreomacular interface. Two cases of vitreomacular traction were analysed by advanced three-dimensional (3D) SD-OCT imaging. En-face OCT permitted localisation of the exact point of attachment of vitreous to retina. A comprehensive view of the surface topography and anatomical configuration of vitreomacular affection was revealed by 3D imaging with segmentation technique. Macular change analysis programme revealed progression to full-thickness macular hole in the second case. Non-invasive high-resolution SD-OCT imaging has transformed the understanding and management of vitreomacular traction. Its role is further reinforced by the introduction of ocriplasmin for management of vitreomacular adhesions.
光谱域光学相干断层扫描（SD-OCT）是一种非侵入性工具，可对玻璃体黄斑界面进行前所未有的成像和分析。通过先进的三维（3D）SD-OCT成像分析了两例玻璃体黄斑牵拉病例。正面OCT能够定位玻璃体与视网膜的确切附着点。采用分割技术的3D成像揭示了玻璃体黄斑病变的表面地形和解剖结构的全貌。黄斑变化分析程序显示第二例病例进展为全层黄斑裂孔。非侵入性高分辨率SD-OCT成像改变了对玻璃体黄斑牵拉的认识和处理方式。用于治疗玻璃体黄斑粘连的ocriplasmin的引入进一步强化了其作用。
