[Loiasis (African eye worm): about a case].

The purpose of our study is to report a case of loiasis producing ocular manifestations in a patient living in the Sahel region, (non-endemic area). The study involved a 25-year old man admitted to ophthalmology consultation with foreign body sensation in the right eye. Ophthalmological examination objectified a tortuous, motile, translucent worm measuring around 4cm under the bulbar conjunctiva of the right eye. After surgical non-traumatic extraction, parasitological examination confirmed the diagnosis of loiasis, a parasitosis mainly occurring in African forests. As a result of population movements, it can occur everywhere in the world. It is essential to recognize it during consultations.
