This research division studies environmental effects on incidence of ocular diseases. In quantitative studies of radio frequency electromagnetic spectrum effects on eyes, we have examined ocular effects from exposure to wavelengths encountered in daily life by experimentation on rabbit eyes. Our research on ocular exposure to ultraviolet (UV) wavelengths utilizes a human like mannequin equipped with UV sensors, and evaluates the efficacy of sunglasses, eye glasses and other accessories in offering eye protection against harmful exposure.
To investigate and analyze associations among ocular UV exposure and cataract, pterygium, and pinguecula, we have conducted longitudinal epidemiological studies on eyes in Japan (Ishikawa) and Iceland, epidemiological surveys on blindness and UV-related eye disease in Tanzania, and ocular epidemiological studies in domestic and international regions with different climate conditions. In our epidemiological study on UV-related ocular diseases targeting Japanese and Taiwanese children, we have examined the effects of ocular UV exposure in childhood.
In 2013, a longitudinal study on radiation exposure dose and incidence of lens opacity in emergency workers of TEPCO (Tokyo Electric Power Company, Inc.) Fukushima Daiichi Nuclear Power Plant was commenced, and is envisaged to include approximately 20,000 subjects.
