目的：评估同轴双波长光学相干断层扫描（OCT）设备（标记为Hydra-OCT）的可行性和安全性。方法：无眼部病变的健康受试者进行视网膜成像，使用Hydra-OCT同时测量840和1,072 nm波长的视网膜扫描。测量前后分别对最佳矫正视力和患者舒适度进行评估。两个波长的OCT图像进行了比较，由5个独立的分级者使用主观grading scheme.Results：共30名参与者（8名女性和22名男性），平均年龄为26.5岁（范围从19到55岁）的30只眼睛。在每个受试者中进行双波长图像采集。使用Hydra-OCT成像对参与者进行的努力和舒适度评估显示，与市售OCT机器相比，该值相当。没有不良事件的报告，视力没有改变的Hydra-OCT. Imaging之间的系统是compared.Conclusions：这项研究提供了证据的可行性和安全性的同轴双波长OCT成像方法在现实生活中的条件。新型Hydra-OCT成像设备可以为视网膜和脉络膜疾病的病理学提供额外的见解。
Purpose:To evaluate the feasibility and safety of a coaxial dual-wavelength optical coherence tomography (OCT) device (marked as Hydra-OCT).Methods:Healthy participants without ocular pathology underwent retinal imaging using the Hydra-OCT allowing for simultaneous measurement of retinal scanning of 840 and 1,072 nm wavelength. Before and after measurement, best-corrected visual acuity and patients’ comfort were assessed. Representative OCT images from both wavelengths were compared by 5 independent graders using a subjective grading scheme.Results:A total of 30 eyes of 30 participants (8 females and 22 males) with a mean age of 26.5 years (range from 19 to 55 years) were included. Dual-wavelength image acquisition was made possible in each subject. The participant’s effort and comfort assessment using the Hydra-OCT imaging revealed an equivalent value as compared to the commercially available OCT machine. No adverse events were reported, and visual acuity was not altered by the Hydra-OCT. Imaging between the systems was comparable.Conclusions:This study provides evidence for the feasibility and safety of a coaxial dual-wavelength OCT imaging method under real-life conditions. The novel Hydra-OCT imaging device may offer additional insights into the pathology of retinal and choroidal diseases.
