Eyelid trauma with canalicular laceration is an ophthalmic emergency requiring prompt diagnosis and treatment to preserve the function of the lacrimal system and prevent late complications^1-3. These lacerations are commonly caused by blunt or penetrating trauma to the medial eyelid region and are often associated with domestic, sports, or road accidents^2,3. The case shown in the video involves a pet dog bite, a trauma mechanism that frequently causes complex eyelid injuries².

A thorough clinical assessment is essential, and any wound near the medial canthus should raise suspicion of canalicular involvement^1,3. Diagnosis can be confirmed by probing and irrigation of the lacrimal system1. Standard treatment involves early surgical reconstruction, ideally within 24–48 h after trauma, ensuring proper anatomical repair and canalicular intubation to maintain lacrimal system patency^1-4.

Employing the correct approach significantly reduces the risk of chronic epiphora, canalicular stenosis, and eyelid deformities, thereby improving both functional and cosmetic outcomes^1,3-5.
