Filter by:Canadians fear loss of vision more than any other disability. Vision loss has an enormous impact on quality-of-life and is extremely costly from a societal and economic perspective. In 2001, more than 600,000 Canadians were estimated to have severe vision loss, accounting for 17% of total disability in Canada. One in 9 individuals experience severe vision loss by 65 years of age; however, this increases to 1 in 4 individuals by 75 years. The financial cost of vision loss in Canada is $15.8 billion per year. There is a general perception that vision loss is "normal with aging" but 75% of vision loss is estimated to be preventable. The major causes of severe vision loss are age-related macular degeneration (ARMD), glaucoma, particularly primary open-angle glaucoma (POAG), and diabetic retinopathy (DR). Canada is headed for an epidemic of age-related eye disease and, unless something is done to prepare for this, severe vision loss will have significant consequences in terms of societal and economic costs. Through this proposed Research Program, and in conjunction with the investigators international academic and private sector partners, the investigators will build and develop unique quantitative imaging technologies to permit non-invasive assessment of visual changes, structural changes in the thickness of the retina at the back of the eye and also changes in the amount of blood flowing through the blood vessels that feed the retina with oxygen. This research will add to the investigators basic knowledge in predicting the development of sight-threatening change in patients with the three diseases, and facilitate earlier detection of the problem to help us discover earlier treatments for people with these conditions. The reliability of each imaging technology will be assessed by determining its ability to differentiate between diseased and healthy eyes. Cross-sectional analyses at yearly intervals, as well as change over time analyses, will be undertaken.
Glaucomatous damage not only occurred to retinal ganglion cells in the eyes, but went across optic nerves, visual chiasm, lateral geniculate nucleus (LGN) and finally the visual cortex; the neural degenerations could be identified through the whole visual tract, which suggests the central nerve system may play a vital role in the progression of glaucoma. The investigators used MRI to investigate changes of visual pathway in vivo.
The purpose of this study is to evaluate the safety and effectiveness in lowering intraocular pressure (IOP) utilizing an experimental lotion containing 0.1% Brimonidine that is applied to the outside of one eyelid.
Safety and IOP (intraocular pressure) lowering effect of DE-111 ophthalmic solution will be evaluated in open-angle glaucoma or ocular hypertension patients, in an open-label, multicenter study.
DE-111 ophthalmic solution will be evaluated for superiority in comparison with Timolol ophthalmic solution 0.5%, in IOP(intraocular pressure ) -lowering effect in primary open-angle glaucoma or ocular hypertension patients, in a multicenter, randomized, double-masked, parallel-group comparison study. Safety will be compared and evaluated as well.
DE-111 ophthalmic solution will be evaluated for superiority in comparison with Tafluprost 0.0015% ophthalmic solution, or for non-inferiority in comparison with Tafluprost 0.0015% and Timolol ophthalmic solution 0.5% used concomitantly, in IOP(intraocular pressure) -lowering effect in primary open-angle glaucoma or ocular hypertension patients, in a multicenter, randomized, double-masked, parallel-group comparison study. Safety will be compared and evaluated as well.
The purpose of this study was to assess patient preference regarding ocular comfort of AZARGA® compared to COSOPT® after one week instillation of each study medication.
The aim of the study is to evaluate the effectiveness and the safety of the EYEOP treatment using High Intensity Focused Ultrasound in refractory glaucoma patients.
The purpose of this study was to assess the safety and intraocular pressure (IOP)-lowering efficacy of changing to DuoTrav® from prior timolol 0.5% monotherapy in participants with open-angle glaucoma or ocular hypertension.
An open-label, non-comparative, pilot evaluation of the 24-hour ocular hypotensive efficacy of AR-12286 in patients with open-angle glaucoma or ocular hypertension
