PURPOSE This prospective, randomized, double-masked, crossover trial was conducted to evaluate the clinical effectiveness of progressive addition lenses (PALs) compared with single-vision lenses (SVLs) on myopia progression in Japanese children. METHODS Ninety-two children fulfilling the inclusion criteria (age: 6-12 years, spherical equivalent refractive(More)
Two siblings who exhibited hereditary parkinsonism with pyramidal signs and cerebellar ataxia are reported. Anticholinergics had a dramatic beneficial effect in both cases, but levodopa did not. This responsiveness, which is similar to that reported in patients with Joseph's disease, suggests dysfunction of an "indirect pathway" involving the globus(More)
Activity of serotonin N -acetyltransferase (NAT), a key regulatory enzyme in melatonin biosynthesis, was detected in the rat lens. NAT activity in the lens showed significant diurnal variation in vivo and in vitro, peaking during the period of darkness, when the lenses were maintained under 14 hr light/10 hr dark cycle. Cultured lenses exhibited a circadian(More)
Although a 0.3 Bangerter filter, which reduces visual acuity, is frequently used for treating moderate amblyopia, the effects on gross stereopsis are not well known. This study quantitatively evaluated whether gross stereopsis is degraded by a Bangerter filter. Seven healthy subjects (median age: 29 years) participated in this psychophysical study. Targets(More)
BACKGROUND Retinal and optic disc perfusion in nonarteritic anterior ischemic optic neuropathy (NAION) is incompletely understood. Our aim was to investigate the characteristics of the microvascular structures at the peripapillary area and optic disc, and their associations with retinal structure and function in patients with NAION. METHODS We conducted a(More)
et al. Efficacy of column scatter plots for presenting retinitis pigmentosa phenotypes in a Japanese cohort. Purpose: We evaluated the efficacy of column scatter plots to describe genotype– phenotype correlations in a Japanese cohort with retinitis pigmentosa (RP). Methods: Clinical records of 121 patients with RP with identified causative mutations were(More)
