There is a paucity of reliable information on the prevalence and causes of blindness in sub-Saharan Africa, and this produces problems in designing and evaluating blindness prevention programmes. To address this problem and to provide baseline data for the evaluation of such programmes, the government of Malawi, in conjunction with a number of agencies, conducted a population-based prevalence survey of ocular disease in the Lower Shire River Valley in southern Malawi, an area where blindness is common. The prevalence of bilateral blindness found (1.27%) is similar to that in other developing countries and represents a significant public health problem. At least 60% of this blindness is preventable or easily reversible.
关于撒哈拉以南非洲失明的患病率和病因,可靠信息匮乏,这给失明预防项目的设计和评估带来了问题。为解决这一问题并为评估此类项目提供基线数据,马拉维政府与多个机构合作,在马拉维南部下希雷河谷开展了一项基于人群的眼病患病率调查,该地区失明现象普遍。所发现的双眼失明患病率(1.27%)与其他发展中国家相似,是一个重大的公共卫生问题。这种失明中至少60%是可预防的或易于逆转的。
