Myopia is a refractive error of the eye that is prevalent worldwide. The most extreme form, high myopia, is usually associated with other ocular disorders such as retinal detachment, macular degeneration, cataract, and glaucoma, and is one of leading causes of blindness. The etiology is complex and has not been fully elucidated. In this study, we identified(More)
The development of myopia is associated with decreased ocular scleral collagen synthesis in humans and animal models. Collagen synthesis is, in part, under the influence of cyclic adenosine monophosphate (cAMP). We investigated the associations between cAMP, myopia development in guinea pigs, and collagen synthesis by human scleral fibroblasts (HSFs).(More)
PURPOSE BH3-like motif containing, cell death inducer (BLID) and LOC399959 are two genes associated with the single nucleotide polymorphism (SNP) rs577948, which is a susceptibility locus for high myopia in Japanese subjects. The purpose of this study was to determine if BLID and LOC399959 are associated with high myopia in Chinese Han subjects. METHODS(More)
PURPOSE To investigate the pathophysiology of Leber's hereditary optic neuropathy (LHON). METHODS Seventy-one subjects from three Chinese families with LHON underwent clinical, genetic, molecular, and biochemical evaluations. Biochemical characterizations included the measurements of the rates of endogenous, substrate-dependent respirations, the adenosine(More)
PURPOSE To investigate whether myopia development is associated with changes of scleral DNA methylation in cytosine-phosphate-guanine (CpG) sites in the collagen 1A1 (COL1A1) promoter and messenger RNA (mRNA) levels following murine form deprivation myopia. METHODS Fifty-seven C57BL/6 mice (postnatal day 23) were randomly assigned to four groups: (1)(More)
PURPOSE To investigate the prevalence and spectrum of mitochondrial ND4 mutations in subjects with Leber's hereditary optic neuropathy (LHON). METHODS A cohort of 1281 Chinese Han probands and 478 control subjects underwent clinical and genetic evaluation, and sequence analysis of mitochondrial (mt) DNA, as well as enzymatic assay of NADH:ubiquinone(More)
PURPOSE To investigate the role of mitochondrial haplotypes in the development of Leber's hereditary optic neuropathy (LHON) associated with the ND4 G11778A mutation in Chinese families. DESIGN Eight Han Chinese families with maternally transmitted LHON were studied using clinical, genetic, and molecular evaluations. PARTICIPANTS One hundred sixty-seven(More)
PURPOSE To investigate the molecular pathogenesis of Leber's hereditary optic neuropathy (LHON) in Chinese families. METHODS A cohort of 1218 Han Chinese subjects with LHON and 316 control subjects underwent the clinical and genetic evaluation and molecular analysis of mitochondrial (mt)DNA. RESULTS The age at onset of optic neuropathy in these subjects(More)
Purpose Usage of different types of contact lenses is associated with increased risk of sight-threatening complications. Changes in the ocular microbiome caused by contact lens wear are suggested to affect infection development in those individuals. To address this question, this study compares conjunctival microbial communities in contact lens wearers with(More)
PURPOSE The purpose of this study was to investigate the mutational incidence and spectrum of mitochondrial ND1 gene in subjects with Leber's hereditary optic neuropathy (LHON). METHODS A cohort of 1281 Han Chinese probands and 478 control subjects underwent sequence analysis of mitochondrial (mt)DNA. Resultant variants were evaluated for evolutionary(More)
