  Traumatic brain injury is a major public health problem that affects millions of people annually and hundreds of people experience brain injury daily. Many of these individuals develop visual symptoms. Optometrists play a ...

• A System for Ocular Surface Temperature Measurement Using Infrared Thermography 

  Zare Bidaki, Ehsan (University of Waterloo, 2022-01-20)

  Background: Ocular surface temperature (OST) is affected by changes in the physiology of the eye caused by normal homeostasis, environmental changes, or systemic and local disease. OST can help a physician to diagnose eye ...

• 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 ...

• Uptake and release of preservatives from soft contact lens materials 

  Yee, Alan (University of Waterloo, 2022-01-13)

  Purpose: The purpose of this thesis was to examine the uptake and release of myristamidopropyl dimethylamine (MAPD) and polyhexamethylene biguanide (PHMB) from soft contact lens material using various in vitro models to ...

• Attentional Factors Underlying Binocular Vision Loss in Amblyopia 

  Chow, Amy (University of Waterloo, 2022-01-13)

  Amblyopia is a neurodevelopmental disorder of vision that results from abnormal visual experience during early development. In addition to significant vision loss in one eye, individuals with amblyopia experience binocular ...

• Stimulus characteristics of a novel air-based multiple stimulus aesthesiometer 

  Mungalsingh, Melanie (University of Waterloo, 2022-01-05)

  Purpose: To (1) develop a novel air-based aesthesiometer capable of producing and applying multiple stimuli separated either by time or space; (2) identify the stimulus airflow characteristics and confirm the consistency ...
