Old canalicular laceration repair: a retrospective study of the curative effects and prognostic factors
Journal Title: International Journal of Ophthalmology - Year 2017, Vol 10, Issue 6
Abstract
"AIM: To investigate the epidemiology and surgical outcomes of old canalicular laceration and analyze the variables impacting on the prognosis of reparation. METHODS: A retrospective review of all old canalicular laceration repairs from Jan. 1, 2008 to Dec. 30, 2015 was performed. Analyzed data included demographics, mechanisms of injury, the time from injury to repair, causes for delayed repair, old associated injuries, the types of surgery, and the effects of repair using canaliculus anastomosis combined with bicanalicular stent intubation. RESULTS: Totally 148 patients with old canalicular laceration received surgical repair and were enrolled. The mean age at presentation was 32.52 years old (ranged from 3 to 63 years old). The 110 patients (74.32%) were male and 127 patients (85.81%) were adults (≥18 years old). The old upper, lower, and bicanalicular lacerations were found in 5 (3.38%), 39 (26.35%), and 104 patients (70.27%), respectively. The mechanism of old injury was primarily due to motor vehicle accidents (n=53, 35.81%). The mean time from injury to repair was 43.61mo (ranged from 1 to 360mo). Associated old ocular and orbit injuries were found in 65 patients (43.92%), and chronic dacryocystitis in 18 patients (12.16%). The main cause of delayed repair was that doctors or patients didn’t pay attention to the canalicular laceration because of the concurrent severe injuries (n=71, 47.97%). Totally 136 patients (91.89%) with old canalicular laceration underwent canaliculus anastomosis combined with bicanalicular stent intubation. In all of them, 20 patients (13.51%) were combined with dacryocystorhinostomy. In these cases, 132 patients (97.06%) attained anatomic success, 121 patients (88.97%) reported no epiphora (functional success), 11 patients (8.09%) reported significant epiphora anesis (functional improvement), and 4 (2.94%) reported no significant anesis (functional failure). Rates of anatomic success and functional success were significantly correlated with different canaliculus involved. However, rates of anatomic success and functional success were not significantly affected by the time from injury to repair. CONCLUSION: The canalicular anastomosis combined with bicanalicular stent intubation could act as an effective therapeutics for old canalicular laceration."
