BACKGROUND Light information is the most important cue of circadian rhythm which synchronizes biological rhythm with external environment. Circadian misalignment of biological rhythm and external environment is associated with increased risk of depression, insomnia, obesity, diabetes, cardiovascular disease, and cancer. Increased light transmission by(More)
OBJECTIVE This study was conducted to assess dynamic visual acuity (DVA) under pupil dilation. BACKGROUND Pupil dilation may negatively affect driving performance. METHODS Thirty healthy young adults (mean age 29.4 years) with pupil dilation participated in this study as the Mydrin P group. In addition to them, 15 healthy young adults (mean age 28.5(More)
INTRODUCTION Blue light information plays an important role in synchronising internal biological rhythm within the external environment. Circadian misalignment is associated with the increased risk of sleep disturbance, obesity, diabetes mellitus, depression, ischaemic heart disease, stroke and cancer. Meanwhile, blue light causes photochemical damage to(More)
PURPOSE To determine the choroidal thickness (CT) in the macular area of eyes of children with hyperopic anisometropic amblyopia and to compare the thickness with that of fellow eyes and age-matched controls. MATERIALS AND METHODS Twenty-five patients (6.6±2.2 years, mean±SD) with hyperopic anisometropic amblyopia and twenty age-matched controls (6.7±1.9(More)
A 48-year-old woman was struck on the right inferior orbital rim by a gardening device and immediately developed complete visual loss in the right eye. Clinical and imaging evaluations failed to disclose any damage to the globe or optic nerve or to their nearby soft tissues and bones. Within months, ipsilateral optic disc pallor, a nerve fiber bundle visual(More)
In the process of "tatami" mat production, from cultivating to weaving, rush farmers are exposed to "sendo" (dyer's earth) dust using it to prevent fading of the "tatami" mat color. It has been found that the workers tend to develop a relatively early stage of pneumoconiosis after about 20 years of this work. In 1980, 51 male (58.6 years old) and 37 female(More)
PURPOSE To compare the choroidal structure of the subfoveal area in the eyes of children with anisohypermetropic amblyopia to that of the fellow eyes and to age-matched controls using a binarization method of the images obtained by enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS This study was performed at Nara Medical University(More)
PURPOSE To determine the amplitude of pseudoaccommodation and higher-order aberrations with three types of implanted monofocal intraocular lenses (IOLs): aspheric yellow (IQ); spheric yellow (NT); and spheric clear (AT). SETTING Department of Ophthalmology, Nara Medical University, Nara, Japan. METHODS We studied 60 patients who underwent small incision(More)
