Obstruction of the nasolacrimal duct by Ascaris lumbricoides.
Although Ascaris lumbricoides infestation is extremely prevalent in some populations, the nematode is an extremely rare cause of nasolacrimal duct obstruction. Obstruction of the nasolacrimal duct in a 4-year-old Brazilian girl by a young adult A. lumbricoides is reported. In contrast to previously reported cases, the nematode involved the inferior, rather than superior, canaliculus and punctum.
