Thelazia callipaeda: a human case report

We report a rare case of human thelaziasis. A 31-year-old man from Nakhon Pathom, Thailand presented to the hospital with a foreign body sensation in and excessive lacrimation from the right eye for one week. His visual acuity was normal. He gave a history of a fly flying around his face; he then rubbed it against his right eye. Five adult worms were collected from the right eye. Two were removed by the patients and three were removed on the ward, using a small cotton swab, from the conjunctival sac. All five worms were identified morphologically as Thelazia callipaeda. The patient became free of symptoms after the fifth worm was removed.
