Development of a practical machine for a "Glare-Free" near-infrared color fundus camera, andstarted verification at Osaka University Hospital
Nanolux Co., Ltd. (Headquarters: Ushiku City, Ibaraki Prefecture, CEO: Motoshi Sobue) whichdevelops, designs, and manufactures "near-infrared color night vision technology" that enables color
photography even in the dark and Nara Institute of Science and Technology (Nara Prefecture, Ikoma
City, President: Naokazu Yokoya) Professor Atsushi Ota of the Optical Functional Element Science
Laboratory, Graduate School of Science and Technology, have succeeded in developing a practicalmachine that can be used for verification in the medical field of a "Glare-Free fundus camera" that
does not require visible illumination light but shoot with near-infrared light as the light source. Inaddition, Osaka University Graduate School of Medicine Eye Science (Professor: Koji Nishida) andOsaka University affiliated Hospital AI Medical Center (Specially Appointed Professor (Full-time):
Ryo Kawasaki), who are conducting joint research with Nanolux Co., Ltd., have started verification at
the University Hospital (hereinafter referred to as "Osaka University Hospital").
A normal fundus camera is very dazzling because it uses a visible light flash to shoot the fundus,
and with non-mydriasis, the pupils are miotic in the first shot, making repeated shooting difficult andshooting for children. Since this camera uses only near-infrared light and does not use flash light, it
is less invasive than conventional fundus cameras, is safer, and has wide-ranging and detailed
observation of the structure including blood vessels of the eyeball with non-mydriasis. Furthermore,by making it possible to easily capture fundus images with less burden on the patient, it is expectedthat fundus photography will become easier and contribute to early detection of lifestyle-relateddiseases such as hypertension as well as eye diseases.
The newly developed " Glare-Free 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 observe major anatomical sites and normal & abnormal findings with actual patients

using a near-infrared fundus camera to confirm the usability of doctors. Therefore, it would be
extremely clinically meaningful if it could be examined with a near-infrared fundus camera withminimal 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. This research verification isscheduled to continue until March 2021.This camera development was carried out with the supportof the Japan Science and Technology Agency (JST) Strategic Creative Research Promotion Project
ACCEL (JPMJAC1601).

【Camera Image】【Fundus Image】■About Nanolux
Nanolux is an AIST technology transfer venture founded in Tsukuba, Ibaraki Prefecture. We will
promote the commercial use of "near-infrared color night-vision technology" that enables shootingwith only near-infrared rays even in the dark, and contribute to a safe and secure society. Itsapplications are wide-ranging, such as security cameras, in-vehicle cameras, and medical cameras.
Installation costs can be minimized as there is little need to change the structure of traditional
camera products.
