Higher order aberrations and visual function in a young Asian population of high myopes.

Purpose: To examine the associations between higher order aberrations (HOAs), visual performance, demographics, and ocular characteristics in a young Asian population with high myopia.

Methods: This was a retrospective review of military pre-enlistees conducted between March 2014 to September 2018. Visual acuity and contrast sensitivity were tested under photopic, mesopic and simulated night conditions.

A Preliminary Study on Normalized Pattern-Reversal Peripheral Field SSVEPs as a Potential Objective Indicator of Useful Field of View Performance.

Purpose: Currently, the test for useful field of view (UFOV) typically relies on subjective feedback for detecting peripheral targets while attending to a central target. Steady-state visual evoked potential (SSVEP) recorded from the occipital region of the brain has been frequently used as an objective alternative to replace subjective responses. Our aim was to investigate if a short screening test can approximate UFOV performance objectively.

Correlation of structural and electrophysiological changes in the retina of young high myopes.

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 determined if OCT can be used as an alternative screening tool to assess retinal function in young myopic adults.

Methods: This was a prospective study comprising young adults aged between 18 and 25 years with spherical equivalent refraction of worse than -6.

Differences in prevalence of refractive errors in young Asian males in Singapore between 1996-1997 and 2009-2010.

Purpose: To determine the differences in prevalence rates of refractive errors in young Singaporean males over a 13-year period between 1996-1997 and 2009-2010 METHODS: Non-cycloplegic autorefraction data were obtained in a survey of 15,085 young male subjects (mean age 19.5 ± 1.4 years, range 16-25 years) in 1996-1997 using a Nikon NRK-8000 autorefractor.

Pathologic changes in highly myopic eyes of young males in Singapore.

Introduction: This study describes the pathologic changes in the retina of a group of young Asian subjects with myopia worse than -10 diopters spherical equivalent (SE) refraction.

Materials And Methods: The study population consists of 20 male subjects undergoing preemployment screening for public service for a 1-year period from 2009 to 2010. A detailed series of visual tests of function, fundus examination and grading, ocular biometry and posterior segment optical coherence tomography were performed for all eyes.
