title: [A clinical study of dacryocystorhinostomy per nasal endoscope guided by endo-ophthalmic optical fiber].
abstract: OBJECTIVE
  To get a method of dacryocyst allocation for dacryocystorhinostomy per nasal endoscope.
  
  
  METHODS
  The dacryocyst of 7 chronic dacryocystitis cases(8 eyes) were located through nasal cavity guided by endo-ophthalmic optical fiber.
  
  
  RESULTS
  All the 7 patients got successful operations, the bleeding was 10-20 ml during the operation , postoperative recovery was good, no infection occurred. Five patients received operations twice, all of them were detained anaesthetic tubes for 3 to 6 months, dacryocyst rinsing were conducted once per month after extubation. No obstructions and complications occurred after one year follow up.
  
  
  CONCLUSIONS
  Endo ophthalmic optical fiber can be used to locate dacryocyst in dacryocystorhinostomy per nasal endoscope.
