PURPOSE To compare the measurement of the central corneal thickness (CCT) by Visante (Carl Zeiss Meditec, Dublin, California, USA) anterior segment optical coherence tomography (AS-OCT) with ultrasound pachymetry. DESIGN Population-based, cross-sectional study. METHODS Participants were part of a population-based study of 3280 Malay subjects aged 40 to(More)
PURPOSE To determine the distribution of choroidal thickness (CT) and ocular factors associated with CT in high myopic eyes in comparison with emmetropic eyes of young healthy adults. METHODS A case-control study of 648 young, male subjects, including 520 high myopes and 128 emmetropes. Choroidal imaging was performed using enhanced depth imaging spectral(More)
PURPOSE To describe the topography and predictors of peripapillary choroidal thickness (PPCT) in highly myopic eyes of young, healthy, Asian subjects. METHODS A total of 870 young male subjects aged 21.63 ± 1.15 years were recruited from the Singapore military. Choroidal imaging was performed using enhanced depth imaging (EDI) spectral-domain optical(More)
PURPOSE To assess the incidence and risk factors for early corneal haze after myopic photorefractive keratectomy (PRK). SETTING Tertiary eye center, Singapore. DESIGN Retrospective case series. METHODS The refractive results and corneal haze severity 3 months after PRK were analyzed. Eyes were categorized into 4 groups based on haze severity.(More)
PURPOSE Despite a high prevalence of myopia among young East Asian adults, there is a lack of data on the myopic retina structure-function relationship in this group. We examined the association between optical coherence tomography (OCT) and electroretinogram (ERG) measurements in highly myopic young Asian adults to provide this information and also(More)
PURPOSE To determine the prevalence and risk factors of myopic maculopathy and specific optic disc and macular changes in highly myopic eyes of young Asian adults and their impact on visual acuity. DESIGN Prospective cross-sectional study. METHODS In total, 593 highly myopic (spherical equivalent refraction [SER] less than -6.00 diopters [D]) and 156(More)
PURPOSE To investigate the influence of choroidal thickness (CT) on visual acuity (VA) in young persons with extremely high myopia. METHODS We conducted a case-control study of young men with extremely high myopia and controls with emmetropia recruited from a mandatory medical eye review for employment purposes. Retinal and choroidal imaging was performed(More)
