Africa Day: Supporting Advocacy Efforts through Research in Africa

Global Executive Director
Organisation: Vision Impact Institute

For Africa Day, Kristan Gross, Global Executive Director, Vision Impact Institute writes about eye health in Africa and the impact of Uncorrected Refractive Errors in children. As a child, I was fortunate to have family friends who served as missionaries in numerous locations around the world. Perhaps this early introduction to a global mindset laid the…

Prevalence of refractive error in Europe

Abstract To estimate the prevalence of refractive error in adults across Europe. Refractive data (mean spherical equivalent) collected between 1990 and 2013 from fifteen population-based cohort and cross-sectional studies of the European Eye Epidemiology (E3) Consortium were combined in a random effects meta-analysis stratified by 5-year age intervals and gender. Participants were excluded if they…

Increasing Prevalence of Myopia in Europe and the Impact of Education

Purpose To investigate whether myopia is becoming more common across Europe and explore whether increasing education levels, an important environmental risk factor for myopia, might explain any temporal trend. Design Meta-analysis of population-based, cross-sectional studies from the European Eye Epidemiology (E3) Consortium. Participants The E3 Consortium is a collaborative network of epidemiological studies of common…

Global cost of correcting vision impairment from uncorrected refractive error

Objective: To estimate the global cost of establishing and operating the educational and refractive care facilities required to provide care to all individuals who currently have vision impairment resulting from uncorrected refractive error (URE). Methods: The global cost of correcting URE was estimated using data on the population, the prevalence of URE and the number…

Global vision impairment due to uncorrected presbyopia

Objectives: To evaluate the personal and community burdens of uncorrected presbyopia. Methods: We used multiple population-based surveys to estimate the global presbyopia prevalence, the spectacle coverage rate for presbyopia, and the community perception of vision impairment caused by uncorrected presbyopia. For planning purposes, the data were extrapolated for the future using population projections extracted from…

Global magnitude of visual impairment caused by uncorrected refractive errors in 2004

Estimates of the prevalence of visual impairment caused by uncorrected refractive errors in 2004 have been determined at regional and global levels for people aged 5 years and over from recent published and unpublished surveys. The estimates were based on the prevalence of visual acuity of less than 6/18 in the better eye with the currently available…
