Structure and Function in Early Glaucoma
(University of Waterloo, 2017-01-23)Glaucoma is a general term that includes an array of ocular conditions that cause a specific neuropathy of the optic nerve (Greenfield, Bagga, et al. 2003) of which abnormalities associated with this disorder are localized ... -
Studies of Visual Attention
(University of Waterloo, 2009-06-22)Aim The experiment proposed to study the effect of sustained visual attention in an effective visual field of 40 degrees, in cued and uncued conditions with different set-sizes. Methods The participants had a normal ... -
STUDIES ON IMPACT RESISTANCE OF SPECTACLE LENS MATERIALS
(University of Waterloo, 2014-05-01)Introduction: The Canadian Standards Association (CSA) Z94.3-07 ballistic impact test for industrial lenses, tests the ability of a lens material to withstand the impact of a 6.4 mm diameter steel ball travelling at a ... -
Studies on the Optimization of Neuropeptides Detection in the Human Tear Film
(University of Waterloo, 2020-05-13)Introduction: Dry Eye Disease (DED) stems from a disruption of the homeostasis of the tear film (TF), a thin layer of fluid covering the ocular surface. The TF consists of numerous constituents that include proteins, ... -
A Study of Saccade Dynamics and Adaptation in Athletes and Non Athletes
(University of Waterloo, 2004)Purpose: The aim of the study was to delineate differences in saccade characteristics between a population of athletes and non athletes. Aspects specifically investigated were latency, accuracy, peak velocity, and gain ... -
Study of the dynamic interactions between vergence and accommodation
(University of Waterloo, 2005)<em>Introduction:</em> Accommodation (change in ocular focus) and Vergence (change in ocular alignment) are two ocular motor systems that interact with each other to provide clear single binocular vision. While retinal ... -
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 ... -
Talking with and about older adult patients: The socializing power of patient-centered communication in an optometry teaching clinic
(University of Waterloo, 2007-07-31)In a teaching clinic, healthcare students and their supervisors talk with their patients in the examination room and they talk about their patients during teaching consultations outside the examination room. Effective ... -
Tear evaporation rates: What does the literature tell us?
(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 ... -
Tear exchange and contact lenses: A review
(Elsevier, 2015-01)Tear exchange beneath a contact lens facilitates ongoing fluid replenishment between the ocular surface and the lens. This exchange is considerably lower during the wear of soft lenses compared with rigid lenses. As a ... -
The tear ferning test: a simple clinical technique to evaluate the ocular tear film
(Wiley, 2014-08-20)A healthy tear film is very important for many major functions of the ocular surface. Dry eye disease is a significant clinical problem that needs to be solved but the poor correlation between clinical signs and reported ... -
The TFOS Dry Eye Workshop II: Executive Summary
(Elsevier, 2017-08-07)This article presents an Executive Summary of the conclusions and recommendations of the 10-chapter TFOS DEWS II report. The entire TFOS DEWS II report was published in the July 2017 issue of The Ocular Surface. A downloadable ... -
The TFOS International Workshop on Contact Lens Discomfort: Executive Summary
(Association for Research in Vision and Ophthalmology, 2013-10-18)Contact lens discomfort (CLD) is a frequently experienced problem, with most estimates suggesting that up to half of contact lens wearers experience this problem with some frequency or magnitude. This condition impacts ... -
The TFOS International Workshop on Contact Lens Discomfort: Introduction
(Association for Research in Vision and Ophthalmology, 2013-10-18)For many years, the contact lens field had focused on safety associated with contact lens wear—and for good reason, given the lack of understanding of the risk factors and etiology of serious complications such as microbial ... -
The TFOS International Workshop on Contact Lens Discomfort: Report of the Contact Lens Interactions With the Ocular Surface and Adnexa Subcommittee
(Association for Research in Vision and Ophthalmology, 2013-10-18)The report of this subcommittee concerns the impact of contact lenses (CLs) on the ocular surface, with a particular emphasis on CL discomfort (CLD). We define the ocular surface, its regional anatomy, and the physiological ... -
The TFOS International Workshop on Contact Lens Discomfort: Report of the Contact Lens Materials, Design, and Care Subcommittee
(Association for Research in Vision and Ophthalmology, 2013-10-18)Examining the role of the contact lens material, design, and the care system is fundamental to understanding contact lens discomfort (CLD). However, a systematic review that tries to determine the governing factors is ... -
Time Course of Dichoptic Masking in Normals and Suppression in Amblyopes
(Association of Research in Vision and Ophthalmology, 2014-07)Purpose.: To better understand the relationship between dichoptic masking in normal vision and suppression in amblyopia we address three questions: First, what is the time course of dichoptic masking in normals and amblyopes? ... -
