A normal fundus camera shoots the fundus using a flash of visible light, so it is very dazzling, and with non-mydriasis (natural-sized pupil), the pupil shrinks in the first shot, making repeated shooting after that difficult. There were restrictions such as the fact that it was difficult to take pictures with children.

　The developed camera uses only near-infrared light and does not use flash light, so it is less invasive than conventional fundus cameras, is safer, and has a wide range of detailed structures that include mydriasis and blood vessels in the eyeball. You can make an observation.Furthermore, by making it possible to easily capture fundus images with less burden on the patient, it is expected that fundus photography will become easier and contribute to early detection of lifestyle-related diseases such as hypertension as well as eye diseases. Has been done.

　This "non-glare fundus camera" has achieved miniaturization and high operability by combining Nanolux's near-infrared color fundus camera NLX-FD001 with a cylindrical lens integrated with near-infrared illumination.In addition, the purpose of verification at Osaka University Hospital is to photograph major anatomical sites and abnormal findings in normal subjects and actual patients using a near-infrared light fundus camera, and to confirm the usability of doctors. Therefore, it is extremely clinically significant if it can be inspected with a near-infrared light fundus camera with minimal invasiveness.So far, more than 10 photographs have been taken at hospital sites, and it has been confirmed that there is no problem in practical operation.The verification period is scheduled from October 2020 to March 10.
