Enterobious vermicularis induced infectious keratitis following penetrating keratoplasty

Abstract

A 28-year-old man with a prior history of penetrating keratoplasty in the left eye for total corneal melt presented with a 3-day history of a red, painful left eye. On examination, he was found to have graft infiltrates. Microscopic examination of wet mount preparation of corneal scrapings revealed the presence of embryonated eggs of E. vermicularis. Cellophane (scotch) tape preparation from perianal region also revealed embryonated eggs of E. vermicularis as well as live adult worms. Ocular and adnexal involvement by E. vermicularis is extremely rare. Here, we report the first case of infection of a corneal graft with E. vermicularis.
