Fatigue related impairments in oculomotor control are prevented by caffeine
(Nature, 2016-05-25)Strenuous exercise can result in an inability of the central nervous system to drive skeletal muscle effectively, a phenomenon known as central fatigue. The impact of central fatigue on the oculomotor system is currently ... -
Fine Motor Skills of Children With Amblyopia Improve Following Binocular Treatment
(Association for Research in Vision and Ophthalmology, 2016-09-08)Purpose: The purpose of this study was to determine whether reduced fine motor skills in children with amblyopia improve after binocular treatment and whether improvements are sustained once treatment has ceased. Methods: ... -
Fish (Oreochromis niloticus) as a Model of Refractive Error Development
(University of Waterloo, 2009-01-13)Myopia is a common ocular condition worldwide and the mechanism of myopia is still not clear. A number of animal models of myopia and refractive error development have been proposed. The fact that form deprivation myopia ... -
Fixational eye movements in strabismic amblyopia
(University of Waterloo, 2013-04-29)Purpose: To test the hypothesis that the fixational stability (FS) of the amblyopic eye (AME) in strabismics will improve when binocular integration is enhanced through ocular alignment and inter-ocular suppression is ... -
Fluoxetine Does Not Enhance Visual Perceptual Learning and Triazolam Specifically Impairs Learning Transfer
(Frontiers Media, 2016-10-19)The selective serotonin reuptake inhibitor fluoxetine significantly enhances adult visual cortex plasticity within the rat. This effect is related to decreased gamma-aminobutyric acid (GABA) mediated inhibition and identifies ... -
Fundamentals of Protein Adsorption at the Solid-Liquid Interface over Short Time Periods
(University of Waterloo, 2014-12-16)Purpose: To directly measure the quantity and degree of denaturation of biomaterial- adsorbed proteins over short time periods. Methods: Contact lenses were used as model biomaterials as they are widely used, readily ... -
Game play in virtual reality driving simulation involving head-mounted display and comparison to desktop display
(Springer, 2019-11-28)Previous studies have reported the effect of driving simulator games on simulator sickness and eye symptoms experienced by users; however, empirical results regarding the game experience using commercial virtual reality ... -
Gaze strategies for coping with glare under intense contra light viewing conditions – A pilot study
(University of Waterloo, 2011-09-30)Purpose: This is a pilot study to investigate gaze strategies for coping with glare when performing a simple visual task under intense contra light viewing conditions. Method: Twenty-four normally sighted participants ... -
Global motion perception is associated with motor function in 2-year-old children
(Elsevier, 2017-09-29)The dorsal visual processing stream that includes V1, motion sensitive area V5 and the posterior parietal lobe, supports visually guided motor function. Two recent studies have reported associations between global motion ... -
Historical overview of imaging the meibomian glands
(Elsevier, 2013-01)Growing knowledge of the role of the meibomian glands in dry eye disease and contact lens discomfort has resulted in a surge of interest in visualizing these glands within the eyelids. This manuscript provides an overview ... -
Image Restoration Methods for Retinal Images: Denoising and Interpolation
(University of Waterloo, 2015-04-27)Retinal imaging provides an opportunity to detect pathological and natural age-related physiological changes in the interior of the eye. Diagnosis of retinal abnormality requires an image that is sharp, clear and free of ... -
