Choriorétinite toxoplasmique active bilatérale : à propos d’un cas chez un adolescent porteur d’un trait drépanocytaire AS colligé dans le SMIT du CHU du Point G de Bamako

Abstract

Introduction : Active toxoplasmic chorioretinitis is a rare condition in adolescents that can cause irreversible blindness. Ocular toxoplasmosis is the first cause of posterior uveitis which represents a real public health problem. We report a case of a 16-year-old teenager, on the ground of sickle cell disease AS, who came in consultation for reduction of distant bilateral visual acuity in the SMIT of the Point G University Hospital in Bamako (Mali). In his eating habits, he overconsumed the meat of sheep and beef in the form of skewers. The patient presented on physical examination with binocular blurring, photophobia, and bilateral eye redness. Examination of the fundus revealed two foci in the right eye and in the left eye a focus of active toxoplasmic chorioretinitis. The laboratory assessment had shown a positive toxoplasma serology for IgG and IgM. The diagnosis of active bilateral acquired toxoplasmic chorioretinitis was retained in the face of clinical, biological and fundus arguments by biomicroscopy. After six weeks of specific clindamycin-based treatment combined with adjuvants. The course was favourable, marked by the regression of symptoms and the healing of the eye lesions (fundus). Conclusion: Active toxoplasmic chorioretinitis is a condition related to multiple toxoplasmosis disorders, its severity depends on its location. In the face of any decrease in visual acuity, it will be necessary to seek an ocular toxoplasmosis and systematically request a toxoplasmic serology.
