A case of naso-ophthalmic myiasis.

Abstract

Myiasis is defined as an occupational disease and it is mainly seen in people who are in contact with animals, in particular sheep. We detected nasal and external ophthalmomyiasis caused by Oestrus ovis in a 33-year-old male who worked as a research assistant in the faculty of agriculture. The presenting complaints were severe foreign body sensation and discharge in the nose, cough, and foreign body sensation in the right eye. Ophthalmologic examination revealed many moving larvae in the right eye of the patient. Larvae were removed and nasolacrimal duct irrigation was performed through the inferior canaliculus. Endoscopic nasal examination also showed larvae colonies. The larvae were removed under local anesthesia and were taken to the parasitology laboratory, wherein Oestrus ovis was identified. Minimal endoscopic sinus surgery showed nonspecific chronic inflammation.
