The overall goal of the Global Vision Database (GVD) is to develop and deploy new and improved evidence on the prevalence of blindness and vision impairment and its causes, on intervention coverage, to inform and influence global priorities and programs.
The main purposes of GVD are to:
- Provide estimates for the prevalence of blindness and vision impairment and risk factors globally and to make these accessible.
- Advise WHO and other international organizations on the most appropriate methods and assumptions for their global, regional and country level eye health epidemiological estimates
- Advise researchers and public health officials on the different issues involved in the estimation of cause-specific blindness and vision impairment
- Act as repository of high quality population-based studies of blindness and vision impairment data, in order to heighten accuracy of estimates and to securely preserve datasets into the future.
Background
The Global Vision Database has been established by an international consortium of ophthalmologists and optometrists with an interest in the epidemiology of eye disease.
MoreObjectives
Since 2008, the group have compiled a database of over 500 population-based eye surveys published between 1980 and 2020 by systematically reviewing vision-related references in medical literature.
