AIMS To investigate the risk factors for myopia, including near work and outdoor activity, in Singapore Chinese preschool children. METHODS A cross-sectional study, with disproportionate random sampling by 6-month age groups, of 3009 Singapore Chinese children aged 6-72 months was performed. Information on family history, near work and outdoor activity(More)
PURPOSE. To determine the prevalence of amblyopia and strabismus in young Singaporean Chinese children. METHODS. Enrolled in the study were 3009 Singaporean children, aged 6 to 72 months. All underwent complete eye examinations and cycloplegic refraction. Visual acuity (VA) was measured with a logMAR chart when possible and the Sheridan-Gardner test when(More)
PURPOSE The purpose of this study was to evaluate the associations between macular volume and thickness, as assessed by optic coherence tomography (OCT), with refraction and axial length (AL) in children. METHODS A total of 104 Chinese school children (51 girls and 53 boys) 11 to 12 years of age were randomly selected from one school during the 2005(More)
PURPOSE To explore the effect of dominance and laterality on refractive error and axial length. METHODS Ocular dominance was assessed with the hole-in-the-card test in 543 children during their 2006 follow-up visits for the Singapore Cohort study Of the Risk factors for Myopia (SCORM). Data were compared to cycloplegic refractions and axial lengths(More)
AIM To estimate the prevalence of primary angle closure glaucoma (PACG) in European derived populations. METHOD Systematic review and modelling of PACG prevalence data from population studies. PACG was defined according to the ISGEO definition requiring structural and/or functional evidence of glaucomatous optic neuropathy. Prevalence estimates were(More)
BACKGROUND Limited data are published on the ultrasound biomicroscope (UBM) findings of the anterior chamber angle. This work provides a population-based assessment of angle findings and compares 3 modalities for assessing angle dimensions. METHODS A sample of 268 persons who had participated in a population-based study of glaucoma prevalence in Singapore(More)
PURPOSE To examine the pattern of myopia-related macular and optic disc changes in Singapore adults with high myopia (spherical equivalent ≤-6.00 diopters). DESIGN Asian adults with high myopia from 3 population-based surveys. METHODS Adults 40 years and older (n = 359) with high myopia were pooled from 3 population-based surveys in Singapore Asians:(More)
PURPOSE To determine the risk factors for strabismus and amblyopia in young Singapore Chinese children. METHODS A total of 3009 children were recruited for the population-based cross-sectional Strabismus, Amblyopia and Refractive Error in Singaporean Preschoolers Study (STARS). Strabismus was defined as any tropia identified on cover test. Visual acuity(More)
BACKGROUND/AIMS To investigate longitudinal changes in anterior chamber depth (ACD) and axial length (AXL) over 5 years after trabeculectomy surgery in Asian patients with primary glaucoma, and to identify factors associated with these changes. METHODS In this prospective cohort study, phakic subjects with primary glaucoma who underwent trabeculectomy had(More)
Besides the direct economic and social burden of myopia, associated ocular complications may lead to substantial visual loss. In several population and clinic-based cohorts, case-control and cross-sectional studies, higher risks of posterior subcapsular cataract, cortical and nuclear cataract in myopic patients were reported. Patients with high myopia(More)
