66顺彩票appBlindness and vision impairment affect at least 2.2 billion people around the world. Of those, 1 billion have a preventable vision impairment or one that has yet to be addressed. Reduced or absent eyesight can have major and long-lasting effects on all aspects of life, including daily personal activities, interacting with the community, school and work opportunities and the ability to access public services.
Reduced eyesight can be caused by a number of factors, including disease like diabetes and trachoma, trauma to the eyes, age-related macular degeneration and cataracts. The majority of people with vision impairment are over the age of 50 years; however, vision loss can affect people of all ages. Blindness and vision loss are felt more acutely by people in low- and middle-income countries where accessibility and specific government services may be lacking. In those countries, the most common cause of vision impairment in children is congenital cataract.
66顺彩票appTreatment for vision impairment depend on the extent of the vision loss and the cause. For example, surgery can remove cataracts and glasses can help uncorrected refractive errors. Other forms of treatment and rehabilitation can be used to improve outcomes for people with irreversible vision impairment.
Integrated people-centred eye care (IPCEC) can help address the significant eye care challenges that many countries face. IPCEC adopts a health system perspective with four strategies: (i) engaging and empowering people and communities; (ii) reorienting the model of care based on a strong primary care; (iii) coordinating services within and across sectors; and (iv) creating an enabling environment, specifically the inclusion of eye care in national health strategic plans, the integration of relevant eye care relevant data within health information systems, and the planning of the eye care workforce according to population needs.
In 2013, the World Health Assembly agreed to a resolution on eye care. Along with collaborations with Member States and partners, WHO’s work follows the approaches outlined in the publication Universal eye health: a global action plan 2014-2019.
