我们证明了一种新的方法，成像前段，包括睫状肌使用组合和同步的两个光谱域光学相干断层扫描设备（SD-OCT）。在一个SD-OCT中，使用互补金属氧化物半导体晶体管（CMOS）相机和交替参考臂对从角膜到透镜的前段进行成像。另一个用于睫状肌成像的SD-OCT配备有中心波长为1，310 nm且带宽为75 nm的光源。在放松和4.00 D重复刺激状态下进行重复测量，6名受试者的6只眼睛。我们还成像动态变化，在眼前节在一只眼睛在调节。获得眼前节和睫状肌的生物测量值。该组合系统似乎能够同时实时成像的眼前段，包括睫状肌，在体内调节过程中的生物统计学。
We demonstrated a novel approach of imaging the anterior segment including the ciliary muscle using combined and synchronized two spectral domain optical coherence tomography devices (SD-OCT). In one SD-OCT, a Complementary Metal-Oxide-Semiconductor Transistor (CMOS) camera and an alternating reference arm was used to image the anterior segment from the cornea to the lens. Another SD-OCT for imaging the ciliary muscle was equipped with a light source with a center wavelength of 1,310 nm and a bandwidth of 75 nm. Repeated measurements were performed under relaxed and 4.00 D accommodative stimulus states in six eyes from 6 subjects. We also imaged dynamic changes in the anterior segment in one eye during accommodation. The biometry of the anterior segment and the ciliary muscle was obtained. The combined system appeared to be capable to simultaneously real-time image the biometry of the anterior segment, including the ciliary muscle, in vivo during accommodation.
