Abstract
Purpose: To evaluate 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 1072 nm wavelength. Before and after measurement, best corrected visual acuity and patients’ comfort was assessed. Representative OCT images from both wavelengths were compared by five 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. 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 pathology of retinal and choroidal diseases.Keywords
