基线视网膜脉络膜图像从黄斑到外围呈现使用蒙太奇技术的光谱域光学相干断层扫描。扫描长度大约是传统后路扫描的三倍，并提供了新的光谱域光学相干断层扫描图像的正常黄斑外玻璃体视网膜和脉络膜解剖。利用一种新的光谱域光学相干断层成像蒙太奇技术，展示正常患者从黄斑到周围的玻璃体、视网膜和脉络膜的基线图像。22名健康志愿者的26只正常眼睛参与了这项研究。每个受试者通过中央凹获得四个径向光学相干断层扫描的蒙太奇图像。黄斑可见6层视网膜，外视网膜有4条带状。周围未见神经节细胞层。外限定膜、第二带、视网膜色素上皮从黄斑向外周连续圈定。第三带在周围不可见。光谱域光学相干断层扫描蒙太奇图像提供玻璃体、视网膜和脉络膜的广角图像，允许评估外周发现和检查外周和后侧疾病之间的关系。最大扫描长度为36毫米。扫描长度大约是传统后路扫描的三倍，与已知的眼睛尺寸一致。这种方法可以用目前的商用设备实现，并可能有助于临床实践中的决策。
Baseline retinochoroidal images from the macula to the periphery are presented using a montaging technique of spectral domain optical coherence tomography. The scan length is approximately three times than that provided by conventional posterior scanning and provides novel spectral domain optical coherence tomography images of normal extramacular vitreoretinal and choroidal anatomy. To present baseline images of the vitreous, retina, and choroid from the macula to the periphery in normal patients using a novel montaging technique of spectral domain optical coherence tomography. Twenty-six normal eyes of 22 healthy volunteers were enrolled in this study. Montaged images of four radial optical coherence tomography scans through the fovea were obtained from each subject. In the macula, there were six identifiable retinal layers as well as four bands in the outer retina. In the periphery, the ganglion cell layer was not identifiable. The external limiting membrane, the second band, and the retinal pigment epithelium were continuously delineated from the macula to the periphery. The third band was not visible in the periphery. Spectral domain optical coherence tomography montaged images provide wide-angle images of the vitreous, retina, and choroid, allowing for evaluation of peripheral findings and examination of relationships between peripheral and posterior disease. The maximum scan length achieved here was 36 mm. The scan length is approximately three times than that provided by conventional posterior scanning and is consistent with known dimensions of the eye. This method is achievable with current commercially available devices and may contribute to decision making in clinical practice.
