title: Obstruction of the nasolacrimal duct by Ascaris lumbricoides.
abstract: 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.
