There are many other causes of avoidable blindness, including Onchocerciasis (River Blindness), Age-Related Macular Degeneration, and childhood blindness (such as vitamin A deficiency).
- Onchocerciasis (River Blindness) is an insect-borne disease found in Africa, the Middle East and Latin America. Although it remains a serious problem and has caused an estimated half million cases of blindness, global initiatives have succeeded in dramatically controlling the incidence of the infection.
- Age-Related Macular Degeneration affects many older people and ranks as the third most common cause of blindness. Although risk factors include tobacco use, sunlight exposure and genetic tendencies, age is the main cause. While there is no cure, treatments can slow the progress of the disease.
- Childhood blindness refers to a variety of diseases and conditions that occur in young children that can lead to blindness. These vary from region to region, with a main cause being vitamin A deficiency (VAD), which is primarily found in developing countries. Vitamin A supplementation is a simple and cheap method of preventing blindness from VAD.
