PURPOSE To compare the characteristics of early cortical cataract localization in three groups in cataract epidemiologic surveys performed in Reykjavík, Melbourne, and Singapore. METHODS Individuals who had right eyes with an area of cortical opacity less than 20% of the pupil when dilated 7 mm or more were selected as subjects. This included 197 subjects(More)
The authors have conducted cataract epidemiological studies in four climatically and racially different places and compared the data. The survey places were Noto and Amami in Japan, Reykjavik in Iceland, and Singapore. The evaluation and grading of lens opacities were done using graphic analysis of Scheimpflug and retro-illumination images. The prevalence(More)
PURPOSE The purpose of this study is to examine risk factors for nuclear lens opacification in citizens of Reykjavik. METHODS 1,045 persons, 583 females and 462 males aged 50 years and older, were randomly sampled and underwent a detailed eye examination and answered a questionnaire. In all Scheimpflug photography of the anterior eye segment was done(More)
BACKGROUND The number of studies that use objective and quantitative methods to evaluate facial skin aging in elderly people is extremely limited, especially in Japan. Therefore, in this cross-sectional study we attempted to characterize the condition of facial skin (hyperpigmentation, pores, texture, and wrinkling) in Japanese adults aged 65 years or older(More)
OBJECTIVES Heatstroke due to a heat wave during the summer is one of the commonly known health impacts of climate change in Japan. The elderly are particularly at high-risk of developing indoor heatstroke with poor prognosis. This study aims to describe the population among elderlies at high-risk of indoor heatstroke by focusing on the usage of cooling(More)
BACKGROUND In recent years, numerous reports demonstrating the relationship between an increase in the concentration of fine particulate matter (PM2.5) and daily mortality have been released in the United States and Europe. There have been few studies that clearly characterize the short-term effects of particulate matter on the mortality in Japan. We(More)
BACKGROUND It is thought that biological responses to air pollutants affect various heart diseases, with the magnitude of the effect dependent on the specific disease. The short-term effects of fine particulate matter (PM(2.5)) on mortality for heart diseases were examined in 9 Japanese cities from 2002 to 2004. METHODS AND RESULTS Mortality data obtained(More)
The purpose of the present study was to examine, in the aging people, racial and gender differences in the morphology of corneal endothelium as well as the incidence of cornea guttata in two Asian subject groups, one in Singapore and the other in Japan. Four hundred and sixty-five Chinese Singaporeans and 299 Japanese subjects (residents of Monzen-machi,(More)
