Development of Novel Techniques for Measuring Bulbar Conjunctival Red Blood Cell Velocity, Oximetry and Redness
(University of Waterloo, 2009-04-29)
Introduction
The ocular surface provides a unique opportunity to study hemodynamics since the vessels can be visualized directly, without treatment and non-invasively. The availability of instruments to measure various ...
The appearance of hyper-reflective superficial epithelial cells observed using in vivo confocal microscopy
(University of Waterloo, 2010-01-22)
Purpose:
Hyper-reflective superficial cells were an unexpected finding while examining the corneal epithelium using confocal microscopy (CM), during an MSc thesis conducted in 2006 at the University of Waterloo, Canada. ...
An Investigation into the Effect of Increasing Target Size for Visual Sensitivity Measurement in Normals and in Early Glaucoma
(University of Waterloo, 2014-09-02)
The clinical standard method of measurement for clinical visual sensitivity is currently Standard Automated Perimetry with a size III target (SAP III). However, there are many factors that can make the results unreliable. ...
Sensitivity Across the Ocular Surface—Fundamental Findings and Clinical Applications
(University of Waterloo, 2010-04-29)
Current understanding of sensitivity and sensation experienced across the ocular surface remains limited. This project explored the regional variation of corneal sensitivity and transducer function, interaction of sensory ...
Retinal and Optic Nerve Head Vascular Reactivity in Primary Open Angle Glaucoma
(University of Waterloo, 2009-05-14)
The global aim of this thesis was to assess retinal vascular reactivity in glaucoma patients using a standardised hypercapnic stimulus. There is a suggestion of disturbance in the regulation of retinal and optic nerve head ...
Retinal Blood Flow and Markers of Vascular Inflammation and Endothelial Dysfunction in Type 2 Diabetes
(University of Waterloo, 2010-09-01)
Abnormal leukocyte adhesion (i.e. leukostasis) to retinal vascular endothelial cells occurs in early diabetes. The processes of leukostasis have been clearly demonstrated in the vascular endothelium of patients with diabetes. ...
Statistical Analysis of Hartmann-Shack Images of a Pre-school Population
(University of Waterloo, 2010-01-22)
The impact of uncoordinated growth of the optical components of the eye may stimulate different levels of monochromatic aberrations in the growing eyes of the children. This thesis aimed to examine the impact of age, visual ...
Contact lens fitting characteristics and comfort with silicone hydrogel lenses
(University of Waterloo, 2012-02-24)
Purpose
To examine soft contact lens fitting characteristics using anterior segment imaging techniques and comfort. The specific aims of each chapter are as follows:
Chapter 2: To calibrate the new ZEISS VisanteTM ...
Viability Profile of ex vivo Corneal Epithelial Cell Samples
(University of Waterloo, 2011-10-28)
The corneal epithelium is a vital tissue which must retain its integrity to preserve vision and protect against harmful bacterial infections and other insults. Corneal disease represents the second most common cause of ...
Calibration and validation the Dynamic Photorefraction System (DPRS)
(University of Waterloo, 2014-09-25)
Introduction:
Our group has been measuring accommodation in myopic children. The instrument of choice has been the Power Refractor (Multichannel Systems). However, this instrumentation is no longer supported and runs on ...
