title: Botulinum toxin for palliative treatment of epiphora in a patient with canalicular obstruction.
abstract: OBJECTIVE
  To describe the use of botulinum toxin injection of the lacrimal gland for palliative treatment of epiphora secondary to canalicular obstruction from docetaxel therapy.
  
  
  METHODS
  Case report.
  
  
  METHODS
  A 50-year-old female with bilateral canalicular obstruction secondary to docetaxel therapy received botulinum toxin injections (5 units each) into the lacrimal glands of both eyes.
  
  
  RESULTS
  Symptomatic epiphora of the affected eyes was reduced after 2 weeks. No side effects were observed.
  
  
  CONCLUSIONS
  Botulinum toxin injection of the lacrimal gland is an effective palliative treatment for epiphora secondary to canalicular obstruction from docetaxel therapy.
