This retrospective study over 10 years provides data on canalicular lacerations in patients younger than 18 years of age. Of 137 lacerations, 38 (27.7%) met the inclusion criteria. 68.4% were white and 73.7% were male. The mean age was 10.8 years (1.1-17.9). Lacerations were due to dog bites (39.5%), other accidents such as fingers in eyes (21.1%), sports related (18.4%), falls (13.2%) and altercations (7.9%). Lacerations involved the lower lid in 65.8%. All due to dog bites were given IV antibiotics. Isolated lacerations occurred in 36.8%. It showed 13.1% had additional mild self-limiting injuries such as subconjunctival haemorrhage and 5.3% had concomitant orbital fractures. It showed 92.1% of repairs were undertaken in theatre under general anaesthetic and usually within one day of injury. The overall success rate, based on reported complete lack of epiphora, was 89.5%. 31.6% were bothered by eyelid appearance. The authors note that the cause of injuries in children differ to those in adults. These lacerations require monitoring and treatment.
