    • Aspects of Corneal Fluorescein Staining 

      Woods, Jill (University of Waterloo, 2019-04-25)
      PURPOSE Evaluating the cornea for epithelial fluorescein staining is a key element of the ocular examination of contact lens wearers and people with dry eye disease. It has long been viewed as a method of visualizing a ...
    • 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 ...
    • Comparison of meibomian gland dropout using two infrared imaging devices 

      Wong, Stephanie; Srinivasan, Sruthi; Murphy, Paul J.; Jones, Lyndon W. (Elsevier, 2018-11-07)
      Purpose To measure the degree of meibomian gland (MG) dropout in the lower eyelid determined by analysis of images obtained from the LipiView II (LVII) and the Keratograph 5M (K5M). Methods The inferior eyelid of each ...
    • Contemporary Diagnosis and Management of Dry Eye 

      Ngo, William (University of Waterloo, 2016-08-31)
      Introduction Dry eye (DE) disease is characterized by symptoms including, but not limited to, ocular stinging, burning, and tearing. The symptoms can range from being mildly irritating, to severely debilitating and ...
    • 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 ...
    • Infrared Imaging of Meibomian Glands and Evaluation of the Lipid Layer in Sjogren's Syndrome Patients and Nondry Eye Controls 

      Menzies, K. L.; Srinivasan, Sruthi; Prokopich, C. L.; Jones, Lyndon W. (Association for Research in Vision and Ophthalmology, 2015-05-02)
      Purpose.: The purpose of this study was to evaluate meibomian gland dropout and lipid layer thickness (LLT) in patients with and without Sjögren's syndrome dry eye (SS). Methods.: We recruited 11 participants with SS ...
    • Novel methods for the evaluation of the tear film in the diagnosis of dry eye 

      Keech, Adam John (University of Waterloo, 2010-09-27)
      Dry eye is a complex, multi-factorial disease that results in a compromised tear film and ocular surface. Clinicians and researchers alike have historically relied on an individual’s symptoms to diagnose and manage the ...
    • Ocular Discomfort Upon Tear Drying 

      Varikooty, Jalaiah (University of Waterloo, 2003)
      <b>Purpose:</b> Assess the relationship between tear film drying and sensation between blinks. <b>Methods:</b> MATLAB sampled a slitlamp video camera, a potentiometer and a microphone while subjects kept one eye open ...
    • Sjogren's Syndrome: A Clinical and Biochemical Analysis 

      Caffery, Barbara (University of Waterloo, 2009-04-30)
      Sjogren’s syndrome (SS) is a systemic autoimmune disease that presents to eye care practitioners with the hallmark symptom of “dry eye.” Stratifying dry eye patients as Sjogren’s positive or negative is a critical ...
    • Tear evaporation rates: What does the literature tell us? 

      Wong, Stephanie; Murphy, Paul J.; Jones, Lyndon W. (Elsevier, 2017-12-24)
      Purpose A previous literature review reported tear evaporation rates (TERs) from studies conducted on rabbits and humans between 1941 and 2003. Closer examination of the presented data revealed inaccuracies in the reporting ...
