  • Can kynurenic acid cause myelin loss in chicken optic nerves? 

    Gurdita, Akshay (University of Waterloo, 2017-09-27)
    Kynurenic acid (KYNA) is one of many kynurenine intermediate products in the tryptophan metabolism pathway and has been shown to have neuro-activity. Previous work revealed that prolonged infusion of a high dose of KYNA ...
  • Understanding the Mechanisms Underlying Brain Plasticity in Adult Humans 

    Abuleil, Dania (University of Waterloo, 2017-09-22)
    Purpose: The human brain changes signi cantly with age. The plasticity of the visual cortex is thought to decrease into adulthood while childrens' brains are highly plastic. This change in plasticity is thought to be due, ...
  • Global motion perception is associated with motor function in 2-year-old children

    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 ...
  • Characterization of Lipid Deposition on Contact Lenses 

    Qiao, Han (University of Waterloo, 2017-08-30)
    The purpose of this thesis was to evaluate the influence of lipid deposition on silicone hydrogel contact lens materials and to construct an in vitro platform to further explore the effect of lipid interaction with contact ...
  • The TFOS Dry Eye Workshop II: Executive Summary 

    Craig, Jennifer P.; Nelson, J. Daniel; Azar, Dimitri T.; Belmonte, Carlos; Bron, Anthony J.; Chauhan, Sunil K.; de Paiva, Cintia S.; Gomes, José A.P.; Hammitt, Katherine M.; Jones, Lyndon W.; Nichols, Jason J.; Nichols, Kelly K.; Novack, Gary D.; Stapleton, Fiona J.; Willcox, Mark D. P.; Wolffsohn, James S.; Sullivan, David A. (Elsevier, 2017-08-07)
    This article presents an Executive Summary of the conclusions and recommendations of the 10-chapter TFOS DEWS II report. The entire TFOS DEWS II report was published in the July 2017 issue of The Ocular Surface. A downloadable ...
  • Binocular vision and fixational eye movements 

    Nallour Raveendran, Rajkumar (University of Waterloo, 2017-07-19)
    Introduction In observers with amblyopia, abnormal patterns of amblyopic eye (AME) fixational eye movements (FEM) have been associated with monocular (reduced amblyopic eye visual acuity) and binocular sensory deficits ...
  • Stereocoherence thresholds as a measure of global stereopsis 

    Unnisa Begum, Viquar (University of Waterloo, 2017-06-14)
    Purpose: The purpose of this study was to develop a robust and reliable clinical test of stereopsis that is complementary to the conventional disparity threshold tests. Methods: Random dot stereograms containing ...
  • Visual correlates of balance and mobility in older adults: Can visual attention training improve performance? 

    Althomali, Mohammed (University of Waterloo, 2017-05-11)
    Falls among older adults is a serious problem facing our aging population. It is estimated that one in every three older adults aged 70+ fall every year; some of these experience multiple falls. Thirty five percent of ...
  • Binocular Adaptation to +2 D Lenses in Myopic and Emmetropic Children: 

    Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (Wolters Kluwer, 2009-06)
    Purpose. To compare vergence adaptation to +2 D addition lenses in myopic and emmetropic children and to evaluate the influence of the accommodative-vergence crosslink (AC/A ratio) on this adaptation. Methods. Nine ...
  • Effect of near adds on the variability of accommodative response in myopic children 

    Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (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 ...
  • Can current models of accommodation and vergence predict accommodative behavior in myopic children? 

    Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (Elsevier, 2014-08)
    Investigations into the progression of myopia in children have long considered the role of accommodation as a cause and solution. Myopic children show high levels of accommodative adaptation, coupled with accommodative lag ...
  • Binocular adaptation to near addition lenses in emmetropic adults 

    Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (Elsevier, 2008-05)
    Near addition lenses are prescribed to pre-presbyopic individuals for treatment of binocular motor problems such as convergence excess and to control the progression of myopia. To date, no investigation has looked at the ...
  • Effect of heterophoria type and myopia on accommodative and vergence responses during sustained near activity in children 

    Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (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 ...
  • Are high lags of accommodation in myopic children due to motor deficits? 

    Labhishetty, Vivek; Bobier, William (Elsevier, 2017-01)
    Children with a progressing myopia exhibit an abnormal pattern of high accommodative lags coupled with high accommodative convergence (AC/A) and high accommodative adaptation. This is not predicted by the current models ...
  • Unmasking the linear behaviour of slow motor adaptation to prolonged convergence 

    Erkelens, Ian; Thompson, Benjamin; Bobier, William; Munoz, Doug (Wiley, 2016-06)
    Adaptation to changing environmental demands is central to maintaining optimal motor system function. Current theories suggest that adaptation in both the skeletal-motor and oculomotor systems involves a combination of ...
