Retrograde intubation via the sac to seek the lacerted ends and anastomosis in lacrimal canaliculi laceration.

Objective To evaluate the effect of retrograde intubation via the sac to seek the lacerted ends and anastomosis in lacrimal canaliculi division .Methods 105 inpatients(105 eyes)with the canalicular laceration by wound were operated firstly by direct - vision method, trying intubation method,injection method and Greaves' method and show ineffectual , then retrograde intubation is made through an icision over the sac, thenasal end is found and anastomosis is operated. The cases are followed -up and statistically analysed postoperatively. Results All the 105 cases were followed - up for a range time from 6 months to years. 102 cases (97.14 %) obtained anatomical coaptation, none complained of epiphori-a,syringe showed the passages patent and the other 3 cases(2.86% )ob-structed. Conclusion Rotrograde intubation via the sac can very possi-blly found the lacerted ends, and then effectively achieve anastomosis. It' s very effectuive, as an alternative or sometimes the only method.
