title: [Absence of epiphora in patients with a monocanalicular injury without surgical reconstruction].
abstract: OBJECTIVE
  To determine the long-term outcome in patients with a lesion of a single lacrimal canaliculus without surgical correction.
  
  
  METHODS
  Prospective.
  
  
  METHODS
  In the period August 1995-August 1999 16 patients were seen with a monocanalicular trauma. No attempt was made to reconstruct the canaliculus; only the superficial layers were closed (skin and M. orbicularis oculi). At follow-up the patients were asked about epiphora (score of Munk) and the test of Anel and the fluorescein dye disappearance test were carried out.
  
  
  RESULTS
  At follow-up a mean of 13.7 months (range: 3-33) after the trauma the injured canaliculus was totally blocked in all patients. In spite of this, none of the patients experienced epiphora either indoors or outdoors. Tear drainage of the ipsilateral unharmed canaliculus was functioning normally in such a way that epiphora was prevented.
  
  
  CONCLUSIONS
  In patients with a monocanalicular lesion repair of only the superficial layers of the eyelid without reanastomosis of the torn ends of the canaliculus is sufficient to maintain normal tear drainage. This procedure is safe and simple.
