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. | |
