Two areas of the Sudan known to be endemic to onchocerciasis were surveyed for skin and ocular changes, and serum vitamin A levels in patients and normal controls. In Southern Sudan severe eye lesions and blindness are common complications. In Northern Sudan skin lesions predominate, and no case of blindness was recorded. Serum vitamin A levels were found to be adequate in all groups studied. However, patients from Southern Sudan with both eye and skin lesions due to onchocerciasis had the lowest mean serum vitamin A level. The significance of these findings is discussed in relation to the possible aetiological role of vitamin A deficiency in the pathogenesis of ocular complications of onchocerciasis.
