David Jordan · Ophthalmic surgery, lasers & imaging retina · 1996
Conjunctivo-dacryocystorhinostomy with a Jones glass tube serving as a conduit for tear flow is used in patients with epiphora resulting from obstructed canaliculi. The glass tube runs from the medial canthus into the nose. The author describes the use of an extended Jones tube in a patient without a nose.
