Case report: intraocular localization of Mansonella perstans in a patient from south Chad

Abstract

A case of Mansonella perstans infection with visual impairment and a retinal lesion is described. After a course of diethylcarbamazine and a further course of mebendazole the symptoms improved and the microfilariae blood concentration decreased. The symptoms and response to antifilarial treatment strongly suggested the intraocular localization of an M. perstans worm.
