title: [The effect of treating obstructive disease of lacrimal passage by lacrimal plastic operation with Nd:YAG laser].
abstract: OBJECTIVE
  To study the therapeutic effects of Nd:YAG laser on obstructive diseases of the lacrimal passage.
  
  
  METHODS
  693 eyes in 603 cases with obstructive diseases of lacrimal passage, including obstruction of lacrimal puncta (23 eyes), lacrimal duct (192 eyes), nasolacrimal duct (227 eyes), chronic dacryocystitis (231 eyes), and traumatic laceration of lacrimal canaliculus (20 eyes), were treated by lacrimal plastic operation with Nd:YAG laser and the therapeutic effects were compared among the groups.
  
  
  RESULTS
  The cure rates and effective rates of the five diseases were 86.9% and 95.7%, 89.1% and 93.8%, 93.0% and 96.0%, 78.4% and 82.7%, 40.0% and 65.0%, respectively. By Ridit analysis, R +/- S(R) values for each group were 0.921 +/- 0.023, 0.914 +/- 0.009, 0.927 +/- 0.007, 0.856 +/- 0.013, 0.749 +/- 0.055.
  
  
  CONCLUSIONS
  The therapeutic effect on chronic dacryocystitis is less than those of obstruction of nasolacrimal duct and lacrimal duct (P < 0.05). The therapeutic effect on traumatic laceration of lacrimal canaliculus is less than that of the other four groups (P < 0.05). Therefore, it should be restricted on indication for the cases of chronic dacryocystitis and traumatic laceration of lacrimal canaliculus.
