Central Visual Field Assessment in Late Stage Glaucoma
(University of Waterloo, 2006)Glaucoma is defined as a progressive optic neuropathy, characterized by loss of visual function and often associated with high intra-ocular pressure. Testing the patients' visual function with Standard Automated Perimetry ... -
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. ... -
A novel Automatic Optic Disc and Cup Image Segmentation System for Diagnosing Glaucoma using RIGA dataset
(University of Waterloo, 2016-04-07)The optic nerve head (ONH) of the retina is a very important landmark of the fundus and is altered in optic nerve pathology especially glaucoma. Numerous imaging systems are available to capture the retinal fundus and from ... -
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 ... -
Structure and Function in Early Glaucoma
(University of Waterloo, 2016-08-24)Glaucoma is a group of diseases, which exhibit a characteristic optic neuropathy and may result in progressive visual field loss. The most important risk factor is raised intraocular pressure (IOP) usually secondary to ...
