title: [Probing of lacrimal passage on congenital dacryocystitis].
abstract: OBJECTIVE
  To investigate the effects of probing of lacrimal passage on congenital dacryocystitis.
  
  
  METHODS
  474 consecutive infants with congenital dacryocystitis were treated with probing of lacrimal passage. The data were retrospectively analyzed.
  
  
  RESULTS
  In 474 eyes, there were 360 and 122 eyes with or without membranous block respectively, and 356 (98.89%) and 107 eyes (85.25%) with or without membranous resistance were respectively cured with probing of lacrimal passage; there were 12 eyes with stenosis and 8 eyes (66.67%) were cured. In operation, 1 and 3 eyes were respectively suffered from subcutaneous edema and laceration of canaliculus, but there was no baby suffered from infection or asphyxia.
  
  
  CONCLUSIONS
  The effects of probing of lacrimal passage were related to the causes of obstruction of lacrimal passage, and it is very important to scrupulously feel in probing lacrimal passage.
