[Apropos of 1 case of ophthalmologic manifestation of bilharziasis].

We present an ocular manifestation of schistosomiasis. We observed the case of a 10 year old young girl living near a flooding canal of the Niger river. She presented a tumor of the left lid associated with an important ptosis. This tumor resulted from numerous polyps of the conjunctiva. The histological analysis of a biopsy of the conjunctiva made the diagnostic. It was confirmed by the analysis of urine and by the important amelioration of inflammation resulting from a specific therapy.
