Since the estimates of the 90s, the new data based on the world population of 2002 show a reduction in the number of people who are blind or visually impaired, in particular, those who are blind because of infectious causes. But there is an increase in the number of people who are blind or visually impaired due to increasing longevity and the increase of noncommunicable chronic diseases. It will be necessary to adapt the current strategies of prevention and care in order to take into account these demographic and epidemiologic trends.
10 facts on blindness and visual impairment
The WHO Prevention of Blindness (PBL) team works with Member States through WHO regional offices to develop strategies for prevention and control of blindness and visual impairment. Team members, together with our many partners in the field, including NGOs and WHO collaborating centres, work with country-based teams to support the implementation of strategies developed. In addition, to facilitate ongoing strategic planning, the PBL team co-ordinates the collection and dissemination at national, regional, and global levels of data that reflect the burden of visual impairment and the implementation of programme strategies. The principal area of work of the Prevention of Blindness team (PBL) is elimination of avoidable blindness.
