PURPOSE To test the efficacy of an experimental Dual-Focus (DF) soft contact lens in reducing myopia progression. DESIGN Prospective, randomized, paired-eye control, investigator-masked trial with cross-over. PARTICIPANTS Forty children, 11-14 years old, with mean spherical equivalent refraction (SER) of -2.71 ± 1.10 diopters (D). METHODS Dual-Focus(More)
Over the past decade, a number of large clinical trials have provided important information relating to the reliability and repeatability of commonly used paediatric tests of vision and their role in the diagnosis and management of paediatric ocular diseases. The aim of this review is to summarise recent findings on the use of paediatric visual acuity tests(More)
PURPOSE We developed and validated a technique for measuring global motion perception in 2-year-old children, and assessed the relationship between global motion perception and other measures of visual function. METHODS Random dot kinematogram (RDK) stimuli were used to measure motion coherence thresholds in 366 children at risk of neurodevelopmental(More)
Prenatal exposure to recreational drugs impairs motor and cognitive development; however it is currently unknown whether visual brain areas are affected. To address this question, we investigated the effect of prenatal drug exposure on global motion perception, a behavioural measure of processing within the dorsal extrastriate visual cortex that is thought(More)
OBJECTIVES To assess the accuracy of preschool vision screening in a large, ethnically diverse, urban population in South Auckland, New Zealand. DESIGN Retrospective longitudinal study. METHODS B4 School Check vision screening records (n=5572) were compared with hospital eye department data for children referred from screening due to impaired acuity in(More)
Global motion processing depends on a network of brain regions that includes extrastriate area V5 in the dorsal visual stream. For this reason, psychophysical measures of global motion perception have been used to provide a behavioral measure of dorsal stream function. This approach assumes that global motion is relatively independent of visual functions(More)
