[Microfilaruria and ocular onchocerciasis (author's transl)].

A study of the relationship between microfilaruria and onchocercal eye lesions has been carried out among 619 persons in 5 villages of North Benin. There is evidence of a significant relationship between microfilaruria and irreversible eye lesions in men aged 15-34 years. The association of microfilaruria with high numbers of microfilariae in the anterior segment of the eye occurs more in older men.
