Developing algorithms for the analysis of retinal Optical Coherence Tomography images
(University of Waterloo, 2018-09-04)Vision loss, with a prevalence loss greater than 42 million in the United States is one of the major challenges of today's health-care industry and medical science. Early detection of different retinal-related diseases ... -
Effect of Reclining on Retinal Thickness in Diabetes
(University of Waterloo, 2015-01-20)Purpose: Previous studies have shown diurnal variation in retinal thickness in patients with diabetic macular edema (DME) over the course of the day but the cause, presence and magnitude of this variation is controversial. ... -
The Relationship between Retinal Vascular Reactivity and Arteriolar Diameter
(University of Waterloo, 2006-12-18)ABSTRACT Purpose: The primary aim of the study (i.e. Chapter 3) was to compare the magnitude of retinal vascular reactivity in arterioles of varying diameter in healthy, young subjects. The secondary aims were to determine: ... -
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. ... -
Retinal Blood Flow and Vascular Reactivity in Diabetic Retinopathy
(University of Waterloo, 2006-12-18)Introduction Retinal vascular reactivity is impaired in patients with diabetes and is thought to be involved in the onset and progression of diabetic retinopathy (DR). Previous studies that have utilized hyperoxia to ... -
Short-Term Moderately Elevated Intraocular Pressure Is Associated With Elevated Scotopic Electroretinogram ResponsesShort-Term Elevated IOP and Scotopic ERG Responses
(Association of Research in Vision and Ophthalmology, 2016-04-01)Moderately elevated intraocular pressure (IOP) is a risk factor for open-angle glaucoma. Some patients suffer glaucoma despite clinically measured normal IOPs. Fluctuations in IOP may have a significant role since IOPs are ...
