title: Lacrimal streams: the demonstration of human lacrimal fluid secretion and the lacrimal ductules.
abstract: The clinical demonstration of the ductular orifices of the human lacrimal gland is reported. Lacrimal fluid secretion can be shown after instillation of 2% sodium fluorescein. Ductular orifices are visible on biomicroscopy. In keratoconjunctivitis sicca the lacrimal fluid streams appear normal, or to be diminished or absent.
