PURPOSE To determine whether a significant correlation exists between the presence of a bulge in the photoreceptor inner segment/outer segment (IS/OS) line and the best-corrected visual acuity (BCVA) in eyes with resolved macular edema associated with branch retinal vein occlusion (BRVO). DESIGN Retrospective, observational case series. METHODS We(More)
PURPOSE To determine whether a significant correlation exists between the presence of a bulge in the photoreceptor inner segment/outer segment line and the best-corrected visual acuity in eyes after successful rhegmatogenous retinal detachment (RRD) repair. METHODS Patients who had undergone successful RRD repair and had an intact inner segment/outer(More)
PURPOSE To clarify the amount of accommodation per 1.0 mm forward movement of a posterior chamber intraocular lens (IOL). SETTING Department of Ophthalmology, Nara Medical University, Nara, Japan. METHODS A ray-focusing equation of pseudophakic eyes was obtained with the ray-tracing method using Mathematica((R)) computer software (Wolfram). At first, it(More)
PURPOSE To evaluate corneal endothelial changes after hyperopic laser in situ keratomileusis (LASIK) considering overestimation and underestimation of the cell count measurement. SETTING Department of Ophthalmology, Nara Medical University, Nara, Japan. METHODS The data were from the clinical trial of the Nidek EC-5000 excimer laser for hyperopic LASIK.(More)
PURPOSE To evaluate the effect of cataract density on the postoperative refractive outcome. METHODS For 59 nuclear cataract eyes, the axial length was preoperatively measured by the IOL Master (Zeiss, Germany) and ultrasound (US; UD-6000, Tomey, Japan) and the cataract density by EAS-1000 (Nidek, Japan). The prediction error was used as evaluation of the(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)
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)
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)
PURPOSE To analyze the effect of total higher-order aberrations (HOAs) on the range of accommodation in pseudophakic eyes and the size of near-vision optotypes. SETTING Department of Ophthalmology, Nara Medical University, Nara, Japan. METHODS The study comprised 30 patients (44 eyes) who were diagnosed with cataract at Nara University of Medical(More)
