[A case of retinitis in a patient with schistosomiasis (author's transl)].

The authors report a case of pure macular oedema. After ruling out all other etiologies, the diagnosis of schistosomiasis due to Schistosoma mansoni was established, with parasitologic and serologic proofs. The specific treatment was followed up by a progressive restoration associated with an acute increase of eosinophila. The question of ocular damages in schistosomiasis is exposed according to the existant litterature: 1) Presence of schistosoma eggs in the ocular area. 2) Presence of adult schistosome in the eyeball. 3) Ocular troubles assumed to be in relation with the presence of adult worm or to larva.
