Ophthalmomyiasis externa caused by oestrus ovis: A case report

Ophthalmomyiasis, fly larvae infestation of eye, is a rare condition that can have variable presentation depending on the type of fly, ocular structures involved, and level of penetration. A case of ophthalmomyiasis externa presented with foreign body sensation, itching, and redness of eyes for 2 days was documented. Mechanical removal and good local treatment helped the patient. The larva isolated was that of Oestrus ovis (sheep nasal botfly). Ophthalmomyiasis externa is mainly caused by sheep botfly O. ovis and it is more common in farming communities. This infestation is rare in India as very few cases are on records.
