(Molecular Vision, 2013-05-04)Purpose: To quantify the expression of mucin 1, cell surface associated (MUC1) and mucin 16, cell surface associated (MUC16) proteins and messenger ribonucleic acid (mRNA) in a cohort of postmenopausal women (PMW), to ... -
Retinal Imaging: Acquisition, Processing, and Application of Mueller Matrix Confocal Scanning Laser Polarimetry
(University of Waterloo, 2013-05-28)The focus of this thesis is the improvement of acquisition and processing of Mueller matrix polarimetry using a confocal scanning laser ophthalmoscope (CSLO) and the application of Mueller matrix polarimetry to image the ... -
Objective assessment of Visual acuity in infants
(University of Waterloo, 2013-08-06)Purpose Early detection of abnormal visual acuity (VA) is crucial in the identification and management of ocular and visual abnormalities in infants. Currently, the Teller Acuity Cards (TACs) are considered the gold ... -
Use of OCT and Oculus Pentacam HR as Aids to Semi-Scleral Contact Lens Fitting
(University of Waterloo, 2013-09-03)Purpose: To determine whether semi-scleral contact lenses (sSCL) can be appropriately fitted using corneal sagittal depth measurements, and to determine the impact of fit on visual acuity, effect of time on topographic ... -
In Vitro Competitive Binding of Major Tear Proteins to Contact Lenses
(University of Waterloo, 2013-09-27)Purpose To study the impact of incubation solution complexity on protein deposition to silicone hydrogel (SH) contact lenses and the effect of contact lens cleaning solutions on protein activity and removal. Methods The ... -
Morphometric Characterization of Limbal Vasculature using Ultra-high Resolution Optical Coherence Tomography
(University of Waterloo, 2013-09-27)Purpose: The aim of the present study was to compare and investigate morphometric characteristics of limbal vasculature within the superior and inferior limbal regions using ultra-high resolution optical coherence ... -
Cell death and proliferation characteristics of the retina after optic nerve section in chickens
(University of Waterloo, 2013-09-27)Optic nerve section (ONS) is an experimental model for damage of the optic nerve associated with diseases such as glaucoma and optic neuritis. Damage to the optic nerve causes loss of retinal ganglion cells that are ... -
Total Retinal Blood Flow and Retinal Oxygen Saturation in the Major Retinal Vessels of Healthy Participants
(University of Waterloo, 2013-09-27)Introduction: Oxygen delivery, or utilization, is a function of retinal blood flow and blood oxygen saturation. The retinal pigment epithelium (RPE), in particular, has been shown to have the highest levels of metabolic ... -
The Regional Extent of Suppression: Strabismics Versus Nonstrabismics
(Association of Research in Vision and Ophthalmology, 2013-10)Purpose.: Evidence is accumulating that suppression may be the cause of amblyopia rather than a secondary consequence of mismatched retinal images. For example, treatment interventions that target suppression may lead to ... -
Comparison of a new portable digital meniscometer and optical coherence tomography in tear meniscus radius measurement
(Wiley, 2013-10-07)Purpose: Non-invasive measurement of tear meniscus radius (TMR) is useful in the assessment of tear volume for dry eye diagnosis. This study investigates the agreement between a new, portable, slit-lamp mounted, digital ... -
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: 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: 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 ... -
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 ... -
Development of a new grading scale for tear ferning
(Elsevier, 2013-10-25)Purpose: This paper reports on the development of a new tear ferning (TF) subjective grading scale, and compares it with the Rolando scale. Method: TF patterns obtained from tear film samples collected from normal and dry ... -
Branching and size of CTAB-coated gold nanostars control the colorimetric detection of bacteria
(Royal Society of Chemistry, 2014)Rapid detection of pathogenic bacteria is challenging because conventional methods require long incubation times. Nanoparticles have the potential to detect pathogens before they can cause an infection. Gold nanostars have ... -
