The Bureau for the Prevention of Blindness is responsible for the provision of cataract surgery to the rural indigent population of South Africa. It is important for the Bureau to know both the prevalence and the incidence of cataract blindness in the population.
DESIGN, SETTING AND SUBJECTS: Blindness prevalence surveys were conducted in KwaZulu in 1990 and 1993.
The prevalence of cataract blindness was 0.59% (95% confidence interval 0.21) in 1990 and 1993. The prevalence of aphakia was 0.1% in 1990 and 0.2% in 1993, demonstrating a probable increase in the delivery of cataract surgical services, although this had not produced a demonstrable fall in the prevalence of cataract blindness. The calculated annual incidence of cataract blindness was 0.14%.
Among a rural population of approximately 19 million South Africans, there is a backlog of 113,000 unoperated cataract-blind people and an incidence of 27,000 new cataract blind per year. The implications of this backlog for cataract blindness in our rural areas are discussed.
预防失明局负责为南非农村贫困人口提供白内障手术。了解该人群中白内障致盲的患病率和发病率对该局而言很重要。
设计、地点和研究对象：1990年和1993年在夸祖鲁进行了失明患病率调查。
1990年和1993年白内障致盲的患病率为0.59%（95%置信区间0.21）。1990年无晶状体眼的患病率为0.1%，1993年为0.2%，这表明白内障手术服务的提供可能有所增加，尽管这并未使白内障致盲的患病率出现明显下降。计算得出的白内障致盲年发病率为0.14%。
在约1900万南非农村人口中，有11.3万白内障致盲患者有待手术，每年新增2.7万白内障致盲患者。本文讨论了这一积压情况对我国农村地区白内障致盲的影响。
