Public opinion on the application of nuclear technology and radiation could change when a nuclear related event occurs. Japan Atomic Energy Relations Organization has tracked its variation through a nationwide opinion survey in Japan by almost the same way every year since FY 2006. We can identify a continuous long-term fluctuation of Japanese opinion before and after the TEPCO Fukushima Daiichi nuclear disaster using the data.

Methods: We conducted a population-based study, the Montrachet study (Maculopathy Optic Nerve nuTRition neurovAsCular and HEarT diseases), in participants older than 75 years. The history of cardiovascular disease and a score-based estimation of their 10-year risk of cardiovascular mortality (Heart SCORE) were collected.
The Tsuruoka Metabolomics Cohort Study included subjects aged 35-74 years from participants in annual health check-up programs in Tsuruoka, Japan. The gender-specific associations of early age-related macular degeneration (AMD) with systemic and genetic factors was assessed cross-sectionally. Of these, 3,988 subjects had fundus photographs of sufficient quality, and early AMD was present in 12.

To test this, we compared retinal vessel diameter and glaucoma-related parameters between eyes with pseudoexfoliation material (PE+) and fellow unaffected (PE-) eyes of patients with clinically unilateral PEX.
Methods: The medical records of 30 consecutive Japanese subjects were reviewed retrospectively.
Purpose: To report a semiautomated retinal vessel caliber measurement system that measures central retinal artery (vein) equivalent (CRAE [CRVE]) with individual correction for magnification errors under conditions assuming optimal focus.
Methods: The focusing condition of the subject eye fundus camera optical system was individually determined by constructing an optical model of each eye applying its refractive error, corneal curvature, and axial length (AL) to Gullstrand's schematic eye, and by adjusting the position of the camera's focusing lenses using each eye's refractive error. Once the focusing condition of the entire optical system was fulfilled, magnification of the fundus images was calculated using paraxial ray tracing.
Purpose: To develop a classification and grading system for myopic maculopathy.
Design: Development and evaluation of a classification system for myopic maculopathy based on observational case series.
Methods: A comprehensive set of myopic macular lesions was defined via literature review and through consensus meetings among retinal specialists and clinician scientists.
Purpose/aim: To identify retinal vascular features that precede the development of branch retinal vein occlusion (BRVO) by comparing case eyes and fellow eyes.
Materials And Methods: We identified 25 persons who attended an annual health screening program at Osaka Health Science Center, Osaka, Japan, and then developed BRVO in one eye between 1995 and 2009. We retrospectively reviewed retinal images of these subjects taken 1-5 years prior to the development of BRVO and compared the prevalence of retinal vascular features between case eyes and contralateral fellow eyes.
