目的：为正常眼的光谱域光学相干断层扫描（SD-OCT）图像上可见的视网膜和脉络膜层和带的分类制定一个共识命名法。设计：一个具有视网膜成像专业知识的国际小组（International Nomenclature for Optical Coherence Tomography [IN.OCT] Panel）的标准，以定义OCT成像术语的共识。参与者：视网膜专家小组。在会议之前，将一组来自正常眼睛的3张B扫描图像分发给专家组，以独立指定玻璃体、视网膜和脉络膜中解剖标志的命名。对产出进行了仔细审查，制成表格，并将其作为圆桌小组会议讨论的起点。回顾了SD-OCT可见的眼部结构的各个细胞层的解剖标志名称随时间的历史。进行了公开讨论和协商的过程，直到对每个特征采用一致的共识名称。主要结果测量：SD-OCT显示的正常眼部特征的定义。结果：在文献中，各层的定义经常变化，并且通常与视网膜解剖学和组织学不一致。该小组为OCT特征引入了术语“区域”，这些特征似乎局限于特定的解剖区域，缺乏特定反射结构的明确证据。这样的区域包括肌样，椭圆，和交错zones.Conclusions：一个命名系统的SD-OCT输出上看到的正常解剖标志已被提出并通过IN。OCT面板。专家组建议在今后的出版物中使用这一标准化术语。拟议的术语统一可作为未来OCT研究的基础。(C)2014年由美国眼科学会。
Purpose: To develop a consensus nomenclature for the classification of retinal and choroidal layers and bands visible on spectral-domain optical coherence tomography (SD-OCT) images of a normal eye.Design: An international panel with expertise in retinal imaging (International Nomenclature for Optical Coherence Tomography [IN.OCT] Panel) was assembled to define a consensus for OCT imaging terminology.Participants: A panel of retina specialists.Methods: A set of 3 B-scan images from a normal eye was circulated to the panel before the meeting for independent assignment of nomenclature to anatomic landmarks in the vitreous, retina, and choroid. The outputs were scrutinized, tabulated, and used as the starting point for discussions at a roundtable panel meeting. The history of anatomic landmark designations over time was reviewed for the various cellular layers of the ocular structures that are visible by SD-OCT. A process of open discussion and negotiation was undertaken until a unanimous consensus name was adopted for each feature.Main Outcome Measures: Definitions of normal eye features showed by SD-OCT.Results: Definitions for various layers changed frequently in the literature and were often inconsistent with retinal anatomy and histology. The panel introduced the term "zone" for OCT features that seem to localize to a particular anatomic region that lacks definitely proven evidence for a specific reflective structure. Such zones include the myoid, ellipsoid, and the interdigitation zones.Conclusions: A nomenclature system for normal anatomic landmarks seen on SD-OCT outputs has been proposed and adopted by the IN.OCT Panel. The panel recommends this standardized nomenclature for use in future publications. The proposed harmonizing of terminology serves as a basis for future OCT research studies.
