Corneal and other external eye diseases are very common in rural areas of southern Africa. A corneal survey was undertaken in Calvinia in the northwestern Cape to establish the incidence and nature of these disorders. Corneal diseases were found in 20,2% of the population and a further 8,4% had other external eye diseases, giving an overall incidence of 28,6%. However, many of the diseases were degenerative, their incidence rising rapidly with increasing age. Pterygium and climatic droplet keratopathy, both of which are related to actinic damage, were particularly common. The aetiology and management of the most frequently encountered diseases are discussed.
角膜疾病及其他外眼疾病在非洲南部农村地区非常常见。在开普敦西北部的卡尔维尼亚进行了一项角膜调查，以确定这些疾病的发病率和性质。在20.2%的人口中发现了角膜疾病，另有8.4%的人患有其他外眼疾病，总体发病率为28.6%。然而，许多疾病是退行性的，其发病率随着年龄的增长而迅速上升。翼状胬肉和气候性小滴状角膜病变这两种与光化性损伤有关的疾病尤为常见。文中讨论了最常见疾病的病因及治疗方法。
