Globally, uncorrected refractive errors are the main cause of moderate and severe visual impairment. Since 2000, the World Health Organization (WHO), for example, has worked with the National Eye Institute, USA, to undertake standard, population-based surveys of the prevalence of refractive error in all regions of the world among children aged five or seven up to 15 years. The reported numbers are on the rise and the rapidly increasing rates of myopia make it a significant public health concern. The epidemiology of myopia has been gaining attention over the last two decades.
Below will feature a country/region specific map where you will be able to read a few abstracts of corresponding population based studies that have been carried out from the year 2000 onwards. The most current prevalence figures will be highlighted. Stay tuned.
