[Clinical aspects of ocular onchocerciasis in Ivory Coast nine years after the interruption of the vectorial transmission (author's transl)].
Report of 262 ocular controls in Ivorian adults nine years after they left their respective villages in hyperendemic onchocerciasic areas which were flooded consequently to the building up of the Kossou dam. After that period 50 p. 100 of the controlled persons have still a positive skin biopsy. On the other hand, parasitism by Onchocerca volvulus microfilariae and lesions of keratitis punctata have nearly disappeared (respectively 1 and 2 cases). Patients with microfilariae in the anterior ocular camera are very rare (3,4 p. 100) though many patients show definitive changes of the anterior and posterior ocular segments. Such kind of surveys are necessary to have a good evaluation of the regressive evolution of ocular schistosomiasis after the interruption of the vectorial transmission.
