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,(More)
The first population-based study of xerophthalmia in Africa was conducted in the Lower Shire River Valley of Malawi in the autumn of 1983. A total of 5,436 children under six years of age were examined by three survey teams over an eight-week period. The prevalence of active xerophthalmia was 3.9%. Rates for night blindness and active corneal disease were(More)
Blindness in Southern Sudan is thought to be highly prevalent due to the high prevalence of onchocerciasis and trachoma. In addition, socioeconomic development in the area has been low and growth slow. Communities in the South have not changed much having been unaffected by modern institutions more prevalent in the North. Traditional methods of farming,(More)
About 1% of the population of Malawi is blind. The major contributors are cataract (40%), trachoma and other infections (15%) and measles/Vitamin A deficiency (15%). There are 3 ophthalmologists in government service. However, one serves as the director of medical services, and is therefore frequently burdened with administrative duties. In addition, one(More)
A population-based prevalence survey of ocular disease was conducted in the Lower Shire River Valley of Malawi in 1983. A total of 5,436 children less than 6 years of age and 1,664 persons greater than or equal to 6 years were examined. The prevalence of inflammatory trachoma peaked in the 1-2-year-old age group at 48.7% and declined rapidly with age to(More)
An epidemic of Neisseria gonorrheae keratoconjunctivitis in African adults occurred in Malawi in 1983. Sixteen patients, seven females and nine males, aged 18 to 60 years, were admitted to the inpatient ocular services at Queen Elizabeth Central Hospital in Blantyre from 1 February to 28 May 1983, all with severe bilateral purulent keratoconjunctivitis and(More)
A variety of grading schemes have been proposed for the clinical classification of inflammatory trachoma. During a population based study of ocular disease conducted in southern Malawi we tested a simplified version of the current WHO grading scheme. Intraobserver agreement statistics were less than satisfactory for three of four graders. Interobserver(More)
