Correlation of visually evoked intrinsic optical signals and electroretinograms recorded from chicken retina with a combined functional optical coherence tomography and electroretinography system
(Society of Photo Optical Instrumentation Engineers, 2012-02-08)Visually evoked fast intrinsic optical signals (IOSs) were recorded for the first time in vivo from all layers of healthy chicken retina by using a combined functional optical coherence tomography (fOCT) and electroretinography ... -
Development of a new grading scale for tear ferning
(Elsevier, 2013-10-25)Purpose: This paper reports on the development of a new tear ferning (TF) subjective grading scale, and compares it with the Rolando scale. Method: TF patterns obtained from tear film samples collected from normal and dry ... -
Development of an In Vitro Ocular Platform to Test Contact Lenses
(Journal of Visualized Experiments, 2016-06-04)Currently, in vitro evaluations of contact lenses (CLs) for drug delivery are typically performed in large volume vials,1-6 which fail to mimic physiological tear volumes.7 The traditional model also lacks the natural tear ... -
A differential role for the posterior cerebellum in the adaptive control of convergence eye movements
(Elsevier, 2020-02)Introduction The vergence oculomotor system possesses two robust adaptive mechanisms; a fast “dynamic” and a slow “tonic” system that are both vital for single, clear and comfortable binocular vision. The neural substrates ... -
Effect of ambient humidity on the Cochet-Bonnet aesthesiometer
(Springer Nature, 2018-06-19)Purpose: The Cochet–Bonnet (COBO) aesthesiometer is the current standard in corneal sensitivity assessment. This study investigates the influence of ambient room humidity levels on the stimulus force exerted by the ... -
Effect of heterophoria type and myopia on accommodative and vergence responses during sustained near activity in children
(Elsevier, 2012-03-15)The influence of phoria-type and myopia on changes to vergence and accommodation during prolonged near-task was examined in 53 children. Participants were classified into phoria and refractive categories based on near ... -
Effect of near adds on the variability of accommodative response in myopic children
(Wiley, 2011-03)Purpose: Higher variability of accommodative response (VAR) has been reported in myopes and speculated to be a possible risk factor for the progression of myopia. We investigated whether near adds of +2D and −2D were capable ... -
The effect of transcranial direct current stimulation on contrast sensitivity and visual evoked potential amplitude in adults with amblyopia
(Springer Nature, 2016-01-14)Amblyopia is a neurodevelopmental disorder of vision that occurs when the visual cortex receives decorrelated inputs from the two eyes during an early critical period of development. Amblyopic eyes are subject to suppression ... -
The Effects of tDCS Across the Spatial Frequencies and Orientations that Comprise the Contrast Sensitivity Function
(Frontiers Media, 2015-11-27)Transcranial Direct Current Stimulation (tDCS) has recently been employed in traditional psychophysical paradigms in an effort to measure direct manipulations on spatial frequency channel operations in the early visual ... -
Exercise-Induced Fatigue and Caffeine Supplementation Affect Psychomotor Performance but Not Covert Visuo-Spatial Attention
(Public Library of Science, 2016-10-21)Fatigue resulting from strenuous exercise can impair cognition and oculomotor control. These impairments can be prevented by administering psychostimulants such as caffeine. This study used two experiments to explore the ... -
Extended Latanoprost Release from Commercial Contact Lenses: In Vitro Studies Using Corneal Models
(Public Library of Science, 2014-10-09)In this study, we compared, for the first time, the release of a 432 kDa prostaglandin analogue drug, Latanoprost, from commercially available contact lenses using in vitro models with corneal epithelial cells. Conventional ... -
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: ... -
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 ... -
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 ... -
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 ... -
