title: Surgical outcome of pediatric dacryocystorhinostomy in Nepal.
abstract: OBJECTIVE
  To report the indications and surgical outcome of dacryocystorhinostomy (DCR) in children treated at a single tertiary eye hospital in Nepal.
  
  
  METHODS
  The medical records of consecutive pediatric patients who underwent external DCR with silicon tube intubation after failed nasolacrimal irrigation and probing from January 2010 to June 2011 were retrospectively reviewed. Surgical success was defined as resolution of epiphora, normal tear film height, negative fluorescein dye disappearance test and anatomic patency determined by irrigation of the lacrimal system.
  
  
  RESULTS
  The etiology of the nasolacrimal duct obstruction was acquired nasolacrimal duct obstruction (NLDO) in 63%, congenital NLDO in 23%, trauma in 1% and congenital bony abnormality in 1 patient. Of the 38 patients who completed follow-up, 37 (97%) had a successful result.
  
  
  CONCLUSIONS
  External DCR effectively treated a variety of pediatric NLDO etiologies, with a low rate of complications.
