Family physician awareness of Charles Bonnet syndrome.

Background: Charles Bonnet syndrome is characterized by formed visual hallucinations in individuals with vision loss. It is reported that one in five older adults with vision loss suffer from Charles Bonnet syndrome and the suspected lack of awareness amongst family physicians may lead to misdiagnosis and inappropriate treatment.

Objective: To assess Canadian family physicians' awareness of Charles Bonnet syndrome.

Prevalence of visual hallucinations in a national low vision client population.

Purpose: To evaluate the prevalence of visual hallucinations (Charles Bonnet syndrome) in a national population undergoing vision rehabilitation.

Study Design: Cross-sectional survey.

Participants: Participants were 2565 new clients older than 40 years attending a Canadian National Institute for the Blind (CNIB) vision rehabilitation clinic.

The incidence of eye injuries in Canada.

Objective: To provide information concerning the incidence of eye injuries in Canada.

Design: Cross-sectional study.

Participants: The study population consisted of all Canadians over the age of 18 years who agreed to participate in a telephone survey.

The cost of vision loss in Canada. 2. Results.

Objective: This study was conducted to provide the financial underpinnings necessary for effective planning for the provision of eye health services in Canada. Canada is facing an aging demographic and all the major eye diseases are diseases associated with aging. It is essential that we have information based on the best available data to support national and provincial vision health plans.

The cost of vision loss in Canada. 1. Methodology.

Objective: This paper outlines the methodology used to estimate the cost of vision loss in Canada. The results of this study will be presented in a second paper.

Design: The cost of vision loss (VL) in Canada was estimated using a prevalence-based approach.

Relationship between travoprost and central corneal thickness in ocular hypertension and open-angle glaucoma.

Purpose: To evaluate whether treatment with travoprost, an F2a prostaglandin analog, affects central corneal thickness (CCT) and whether intraocular pressure (IOP) response to the medication is related to baseline CCT.

Methods: This was a prospective, interventional, nonrandomized, nonconsecutive, clinical trial. In this multicenter study, 379 total patients, 220 with newly or previously diagnosed open-angle glaucoma (OAG), 141 with ocular hypertension (OHT), and 18 unspecified, were recruited from 15 Canadian sites.

The effect of blue light exposure and use of intraocular lenses on human uveal melanoma cell lines.

Little is known about the effect of blue light on inducing melanocytic malignant transformation. We chose to investigate the effect of blue light (475 nm wavelength) on the proliferation rates of uveal melanoma cells. In addition, we tested two different intraocular lenses to determine the possible effects of ultraviolet absorbing and blue light filtering intraocular lenses on the changes in proliferation.
