Article Synopsis
- - The study aimed to estimate the prevalence of glaucoma in Canada using self-reports and various tests like Frequency Doubling Technology Perimetry (FDT), optic nerve measurements, and intraocular pressure data.
- - Among 2,600-4,100 participants aged 40-79, the findings showed glaucoma prevalence rates ranging from 0.7% to 10.3%, with 16.3% classified as "glaucoma suspects."
- - Notably, 37.5% of those with definite glaucoma didn't know they had the condition, highlighting the importance of awareness and testing.
Background: Public funding of cataract surgery provided in private, for-profit surgical centres increased to help mitigate surgical backlogs during the COVID-19 pandemic in Ontario, Canada. We sought to compare the socioeconomic status of patients who underwent cataract surgery in not-for-profit public hospitals with those who underwent this surgery in private for-profit surgical centres and to evaluate whether differences in access by socioeconomic status decreased after the infusion of public funding for private, for-profit centres.
Methods: We conducted a population-based study of all cataract operations in Ontario, Canada, between January 2017 and March 2022.
Purpose: To investigate the psychometric performance and responsiveness of Catquest-9SF, a patient-reported questionnaire developed to evaluate visual function as related to daily tasks, in patients referred for cataract surgery in Ontario, Canada.
Methods: This is a pooled analysis on prospective data collected for previous projects. Subjects were recruited from three tertiary care centers in Peel region, Hamilton, and Toronto, Ontario, Canada.
Background: Current methods used to estimate surgical wait times in Ontario may be subject to inconsistencies and inaccuracies. In this population-level study, we aimed to estimate cataract surgery wait times in Ontario using a novel, objective and data-driven method.
Methods: We identified adults who underwent cataract surgery between 2005 and 2019 in Ontario, using administrative records.
Background: With an aging population in Ontario, ophthalmologists provide most of their care to older adults, which has prominent human resource implications. In this study, we sought to investigate the supply and demographic characteristics of Ontario's ophthalmologists.
Methods: In this retrospective, population-based analysis, we evaluated cohort demographics, including sex and career stage, of Ontario's ophthalmologists from 2010 to 2019, which we reported using descriptive statistics.
