    Purpose To establish a relationship between the diameter and depth position of vessels in the superior and inferior corneo-scleral limbus using ultra-high resolution optical coherence tomography (UHR-OCT). Methods Volumetric ...
  • 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: ...
  • Assessment of Current and Next Generation of Colour Vision Tests for Occupational Use 

    Almustanyir, Ali (University of Waterloo, 2018-06-19)
    Introduction: Individuals with congenital colour vision deficiencies are at a greater risk of making an error in colour judgment. Computerized colour vision tests are now available to screen for colour vision defects and ...
  • The Validation of a Novel Dynamic Visual Acuity Test, and Examination of the Effects of Different Factors on Dynamic Visual Acuity 

    Hirano, Mariko (University of Waterloo, 2018-05-22)
    Purpose: When a target is in motion, two thresholds can be measured: dynamic visual acuity (DVA, the smallest target size at which an observer can resolve target detail) and speed threshold (the fastest target speed at ...
  • Dose-effect autonomic responses to ocular surface stimulation 

    Alabi, Emmanuel (University of Waterloo, 2018-04-26)
    Introduction: The ocular surface is one of the most densely innervated superficial tissues of the human body supplied extensively by autonomic and sensory nerve fibres. Studies have shown that ocular surface sensory neurons ...
  • 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, ...
