Reversal of iatrogenic punctal and canalicular occlusion

Ophthalmology. 1996 Sep;103(9):1493-7. doi: 10.1016/s0161-6420(96)30478-8.


Purpose: Significant epiphora occasionally develops after therapeutic punctal occlusion. When this complication occurs from combined scarring of the upper and lower proximal canaliculi, correction usually requires a conjunctivodacryocystorhinostomy.

Methods: The authors describe a new microsurgical technique for reversing iatrogenic occlusion of both the upper and lower canaliculi. The relatively straightforward reconstruction uses the remaining canalicular system to create new tear outflow sites.

Results: This procedure has been used successfully to repair eight of nine consecutive cases of iatrogenic canalicular occlusion, with an average follow-up of 2 years.

Conclusion: Iatrogenic canalicular occlusion can be reversed microsurgically without a conjunctivodacryocystorhinostomy.
