External ophthalmomyiasis is an infestation of the eye with larvae of Dermatobia hominis or Oestrus ovis (sheep bot fly). We describe a case of ophthalmomyiasis in a 38-year-old male, who presented with ocular foreign body sensation, redness, pain, and watering of the eye. The causative larvae were removed and sent to the laboratory for identification. By studying morphological features, it was identified as the first instar larvae of O. ovis. The patient was put on topical and oral antibiotics but was lost to follow-up. This is probably the first report from this part of Karnataka.
