  • Visual Functions in Parkinson’s Disease 

    Alhassan, Mosaad (University of Waterloo, 2018-06-19)
    Background: Freezing of gait (FOG) is considered to be a motor disorder symptom that affects some Parkinson Disease (PD) patients; however, it is hypothesized that sensory systems may also be involved in FOG. Purpose: ...

  • The adaptive elements of disparity vergence: Dynamics and directional asymmetries. 

    Erkelens, Ian (University of Waterloo, 2018-04-24)
    Vergence eye movements alter the angle between the two visual axes, creating changes in binocular fixation distance. They are primarily stimulated by retinal image disparities, but can also be driven by inputs from ocular ...
  • The combined effects of benzalkonium chloride and ultraviolet radiation on the bovine lens in vitro 

    Rossy, Jordan (University of Waterloo, 2018-04-23)
    Purpose: To determine the combined effects of benzalkonium chloride (BAK) and ultraviolet radiation (UV) using the primary culture of intact bovine lenses. Methods: Abattoir-provided lenses were dissected from the eyes ...
  • Contact Lenses and Tear Film Lipids. 

    Walther, Hendrik (University of Waterloo, 2017-12-20)
    Introduction Lipids are essential tear components that aid the stability of the tear film (TF) to protect it from excess evaporation. The composition, conformation, and function of TF lipids are jeopardized by external ...
  • Cellular changes at the lid margin 

    Muntz, Alex (University of Waterloo, 2017-11-28)
    PURPOSE: The hypothesis underlying this thesis is that CL wear, lid wiper epitheliopathy (LWE), and symptoms of dryness and discomfort may be manifest as cellular changes of the lid marginal epithelium, as a result of ...
  • The correction of static and dynamic aniseikonia with spectacles and contact lenses 

    McNeill, Suzanne; Bobier, William (Wiley, 2017-02-16)
    We describe a case of where significant anisometropic astigmatism was accompanied with considerable asthenopic symptoms. Symptoms were not alleviated by the prescribing of a partial spectacle correction. Subsequent treatment ...
  • Investigation of vision strategies used in a dynamic visual acuity task 

    Yee, Alan (University of Waterloo, 2017-10-24)
    Purpose: Dynamic visual acuity (DVA), the ability to resolve fine details of a moving target, requires spatial resolution and accurate oculomotor control. Individuals who engage in activities in highly dynamic visual ...
  • Understanding the sensory and motor behavior of accommodation in progressive myopic children 

    Labhishetty, Vivek (University of Waterloo, 2017-09-27)
    Introduction: Accommodation and vergence, in unison, help in maintaining a clear and single binocular vision, a linchpin for normal vision development. Under natural viewing conditions, accommodation and vergence systems ...
  • 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 

    Thompson, Benjamin; McKinlay, Christopher J.D.; Chakraborty, Arijit; Anstice, Nicola S; Jacobs, Robert J.; Paudel, Nabin; Yu, Tzu-Ying; Ansell, Judith M.; Wouldes, Trecia; Harding, Jane E. (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 ...
  • 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 ...

  • 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)
