Canalicular trauma refers to sudden physical injury that results in damage to the lacrimal drainage system of the eye. The lacrimal canaliculi are located within the medial aspect of the eyelid. This area area is unlike the rest of the eyelid because it does not contain a tarsal substructure. Therefore, a force which displaces the eyelid from its strong attachment at the medial canthal tendon, lacrimal, and maxillary bone, tend to cause avulsion in the medial aspect of the eyelid.
