Understanding concussion in para athletes with vision impairment
(University of Waterloo, 2023-02-15)Sports-related concussions occur in para sport as they do in able-bodied sport. There is evidence to suggest athletes with vision impairment (VI) may be more likely to sustain concussion injuries compared to athletes with ... -
Diabetic retinopathy grading with respect to the segmented lesions
(University of Waterloo, 2022-05-19)One of the leading causes of irreversible vision loss is Diabetic Retinopathy (DR). The International Clinical Diabetic Retinopathy scale (ICDRS) provides grading criteria for DR. Deep Convolutional Neural Networks (DCNNs) ... -
Effects of ML-7 on the Actomyosin Networks of the Avian Crystalline Lens
(University of Waterloo, 2022-04-29)Assemblies of contractile proteins such as actin, myosin and myosin light chain kinase (MLCK) are found on the posterior surface of the lens fibre cells. The mechanical properties of chicken lenses, as well as their focal ... -
A differential role for the posterior cerebellum in the adaptive control of convergence eye movements
(Elsevier, 2020-02)Introduction The vergence oculomotor system possesses two robust adaptive mechanisms; a fast “dynamic” and a slow “tonic” system that are both vital for single, clear and comfortable binocular vision. The neural substrates ... -
Impact of contact lens wear on epithelial alterations in keratoconus
(Elsevier, 2021-03)Purpose The purpose of this study was to characterize the central epithelial thickness (CET) of penetrating keratoplasty corneal specimens obtained from patients with keratoconus (KC) and correlate the histological patterns ... -
The Optometric Management of Concussion
(University of Waterloo, 2022-01-31)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
(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
(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
(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
(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
(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 ... -
Ocular Surface Sensory Processing and Signal Detection Theory
(University of Waterloo, 2021-09-28)Purpose: The main aim of the experiments in this thesis is to evaluate the feasibility of using signal detection theory (SDT) to determine the detectability and bias of various ocular surface pneumatic stimuli. Chapter ... -
Modeling age-related ocular media changes using the Farnsworth Munsell (FM) 100-Hue Test
(University of Waterloo, 2021-08-31)Introduction: Evaluation of chromatic discrimination can help diagnose and monitor diseases and disorders of the visual system; however, normal age-related changes can make diagnosing colour discrimination losses challenging. ... -
Changes in corneal thickness in keratoconic eyes with variation in scleral contact lens central clearance
(University of Waterloo, 2021-08-30)Purpose: There has been a resurgence of scleral lens wear, particularly for patients with corneal ectasia, such as keratoconus. This method of lens correction provides good visual acuity for these individuals and is often ... -
Electrophysiological measures of optic nerve function
(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 ... -
Effect of vision-based treatments on visual acuity and motor function in children with amblyopia
(University of Waterloo, 2021-08-19)Purpose: To investigate existing as well as novel vision-based treatments in children with amblyopia and determine the utility of motor function as a potential outcome measure. Methods: Three experiments were conducted. ... -
Development of an in vitro eye model to better represent in vivo physiological conditions
(University of Waterloo, 2021-06-23)Purpose The purpose of this thesis was to optimize a novel in vitro blink model, the OcuBlink, to best mimic the physiological characteristics of the human eye. By improving this in vitro model, the results from in vitro ... -
Non-invasive brain stimulation of the primary visual cortex of healthy adults and individuals with amblyopia
(University of Waterloo, 2021-05-03)Introduction: Amblyopia is a neurological condition that affects the visual cortex and causes visual deficits, typically in one eye. Recovery from amblyopia requires significant visual cortex neuroplasticity to allow for ... -
