Jone's Tube, Canaliculus

Jone's Tube, Canaliculus
When the lacrimal canaliculi have been destroyed or when the eyelids are totally paralyzed or tethered by scar tissue so that the pumping action of the canaliculus is absent a bypass for tear elimination is indicated . A small glass tube is placed to drain the tears from the lacrimal lake into the nose. The widened proximal edge of the tube is visible behind the inner canthus.
