Surgical Management of Ocular Thelaziasis in a Cattle

A cow was presented with excessive lacrimation, watery eyes, conjunctivitis, cloudiness, ulcerative keratitis and corneal opacity in left eye. On detailed clinical examination, eye worm (Thelazia sp.) was seen wriggling in eye with vigorous movement. Eyeworm was removed surgically under auriculo-palpebral, retro bulbar nerve blocks and topical anesthesia. Animal made an uneventful recovery without any complication after twelve post-operative days.
