背景/目标：在未来二十年中，除非为改善发展中国家的眼睛保健作出协调一致的努力，否则预计失明负担将大大增加。改变患病率或盲人数量的证据很少。在16年的时间里测量了马拉维成年人口中盲人患病率和盲人数量的变化。方法：1999年在马拉维奇夸瓦地区进行了一项基于人群的成年人(50岁以上)失明调查。分别记录每只眼的视力和视力丧失的原因。失明的定义是表现出更好的眼睛视力

Evidence of changing prevalence rates or numbers of blind people are few. The change in blindness prevalence and the number of blind people in an adult population of Malawi was measured over a 16 year period.Methods: In 1999 a population based survey of blindness in adults ( age 50+) was conducted in Chikwawa district of Malawi.
