PURPOSE
To demonstrate applicability of high speed spectral optical coherence tomography (SOCT) method for imaging retinal pathologies in clinical conditions.
METHODS
SOCT was performed in 67 eyes with different macular diseases. Examinations were carried out with the prototype SOCT instrument constructed in the Institute of Physics, Nicolaus Copernicus University, Toruń, Poland. A broadband superluminescent diode was used as a light source.
RESULTS
The disturbances of retinal layer structure concerning mainly outer segments of photoreceptors were observed in case of central serous chorioretinopathy and choroidal neovascularization in age-related macular degeneration. Large drusen were often related to significant changes of outer nuclear layer thickness and reflectivity.
CONCLUSIONS
SOCT detects small disturbances of the retinal structure and helps to precisely determine layers involved in different pathologies.
目的
证明高速光谱光学相干断层扫描（SOCT）方法在临床条件下对视网膜病变成像的适用性。
方法
对67只患有不同黄斑疾病的眼睛进行了SOCT检查。使用波兰托伦哥白尼大学物理研究所构建的SOCT原型仪器进行检查。以宽带超发光二极管作为光源。
结果
在中心性浆液性脉络膜视网膜病变和年龄相关性黄斑变性的脉络膜新生血管病例中，观察到主要涉及光感受器外段的视网膜层结构紊乱。大的玻璃膜疣通常与外核层厚度和反射率的显著变化有关。
结论
SOCT可检测到视网膜结构的微小紊乱，并有助于精确确定不同病变所涉及的层次。
