Ocular miasis caused by Oestrus ovis . Report of a case

摘要

Myasis is a parasitism caused by Diptera larvae invasion in humans and animals. Larvae may penetrated the nasal cavity, nasal sinus, ocular globe and other places of the body. The Oestrus ovis is a causative agent in sheep where it is called the Botflay or “head grub” leading to a high morbidity. The infection in humans is very rare but if an infection occurs, secondary effects can produce discapacity. The case we report is a schoolboy 9 years old from Sanare, estado Lara, presenting with eyelid edema, hyperemic conjunctivae and foreign body sensation in the right eye. An enucleation of the right eye was performed and the diagnosis of oestriasis was made by identification of larvae of Oestrus ovis.
