Survey of ocular disease among the Nama people of South West Africa.

Before the survey, a preliminary house-to-house census had been taken to make contact with potential patients. It was hoped to see a representative sample from each age group. The examinations took place at the Hospital at Keetmanshoop, the patients being transported to the hospital from the surrounding dwellings by the university Landrover. A full external ocular examination a, slit-lamp examination, and fundoscopy was carried out on each patient. In those above 20 years of age a bilateral applanation ocular tension reading was taken. All the findings were charted on a special proforma. A total of 68o patients was seen in a period of 12 days; the number in each age group is shown in Table I (overleaf). The present report deals briefly with external ocular disease, ocular movements, uveal tract disease, cataract, retinal and optic nerve disease, glaucoma, and corneal dystrophy. The most striking condition observed was gelatinous corneal dystrophy, which forms the subject of a more detailed communication (see p. 688: Freedman, 1973).
