Research team creates dynamic maps that illustrate global vision loss over two decades

Date Posted: 10/15/2014

Maps that display world trends in vision loss over two decades, between 1990 to 2010, have been published by a team of researchers led by Rupert Bourne, from the Vision and Eye Research Unit at Anglia Ruskin University in Cambridge. The Global Vision Database (GVD) is housed online at; and the maps can be sorted by year, gender, condition (totally blind versus low vision), age (all ages or only adults aged 50 years and older), and are color coded by prevalence. The maps are dynamic, and provide detailed information for each country, by year, when selected. The GVD maps will be maintained by the Vision Loss Expert Group, an international team of 79 optometrists and ophthalmologists who are interested in the epidemiology of eye disease. Since 2008, the group has been collecting data from more than 250 population-based eye surveys that were performed from 1980 to 2012. By creating the maps, the group aims to provide public health officials; researchers; and groups, such as the World Health Organization, with the vital information required to better understand eye disease across the world. In addition, according to Dr. Bourne, "Further maps on causes of vision loss are in development. We hope they will prove invaluable to further developments in preventing blindness."
