    • Effects of Temperature on the Proliferation of Human and Fish Lens Epithelial Cells 

      Li, Ziqing (University of Waterloo, 2019-08-29)
      Crystallins are proteins that confer refractive properties to the crystalline lens. All vertebrate lenses contain α- and β-crystallins, and often a third major crystallin. Crystallins can have additional non-refractive ...
    • Electrophysiological measures of optic nerve function 

      Afari, Clement (University of Waterloo, 2021-08-26)
      The contribution of retinal ganglion cells (RGCs) to human electroretinograms (ERGs) is known, but that of chicken (Gallus gallus domesticus) is not clear. This project seeks to determine the effect of RGC dysfunction on ...
    • Estimation of Heading direction Using Optic Flow 

      Eshnina, Najwa (University of Waterloo, 2019-08-26)
      Background The purpose of this study was to investigate the effect of the reduction of the uniocular light luminance as well as the effect of unequal retinal image sizes by using uniocular size lenses, on the heading ...
    • Evaluation of a Novel Glycoprotein on Commercial Contact Lenses 

      Cheung, Steven (University of Waterloo, 2015-05-22)
      PURPOSE The purpose of this thesis was to evaluate the interaction of a novel glycoprotein, known as proteoglycan 4 (PRG4), with various commercial contact lenses. METHODS PRG4 was investigated for its effects on ...
    • The evaluation of bulbar redness grading scales 

      Schulze, Marc-Matthias (University of Waterloo, 2010-01-12)
      The use of grading scales is common in clinical practice and research settings. A number of grading scales are available to the practitioner, however, despite their frequent use, they are only poorly understood and may be ...
    • Examination of Contact Lenses and Dry Eye Using Evaporimetry 

      Wong, Stephanie (University of Waterloo, 2022-01-14)
      Purpose: Evaporimetry is a non-invasive technique used to assess the stability of the tear film. The test measures the rate of tear evaporation, and has been used to investigate dry eye, contact lenses, and the efficacy ...
    • Exercise-Induced Fatigue and Caffeine Supplementation Affect Psychomotor Performance but Not Covert Visuo-Spatial Attention 

      Connell, Charlotte J. W.; Thompson, Benjamin; Kuhn, Gustav; Gant, Nicholas (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 ...
    • Explainable AI for retinal OCT diagnosis 

      Brar, Amitojdeep Singh (University of Waterloo, 2021-01-20)
      Artificial intelligence methods such as deep learning are leading to great progress in complex tasks that are usually associated with human intelligence and experience. Deep learning models have matched if not bettered ...
    • Extended Latanoprost Release from Commercial Contact Lenses: In Vitro Studies Using Corneal Models 

      Mohammadi, Saman; Jones, Lyndon W.; Gorbet, Maud (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 

      Connell, Charlotte J. W.; Thompson, Benjamin; Kuhn, Gustav; Claffey, Michael P.; Duncan, Shelley; Gant, Nicholas (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 

      Webber, Ann L.; Wood, Joanne M.; Thompson, Benjamin (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 

      Shen, Wei (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 

      Nallour Raveendran, Rajkumar (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
