RESUMO
The authors report the first case observed in Cameroon of an intraocular localization of the nematode Gnastostoma spinigerum. The course of about 3 months presented three phases. The first one consisted of pains in the right hypochondrium, with scapulalgia during three weeks, probably correlated with the crossing of the digestive wall and intraocular migrations. The second phase consisted of ambulatory oedema in the face and neck during three weeks. The last phase consisted of a localization of the parasite in the right eye anterior chamber. After three weeks' observations the surgical extraction of a living gnastostoma larva was carried out. The biological signs were an increase of the sedimentation rate, hyperleucocytosis with marked eosinophilia during the first two phases of the disease. These symptoms became normal after the ocular localization. From the functional point of view the result was better than foreseen.
