Structure
The medial palpebral (canthic) ligament passes from the medial ends of both tarsal plates and insets into the anterior lacrimal crest and the frontal process of the maxilla (bone forming part of the orbital cavity). As it inserts into the tarsal plates, the ligament splits to surround the lacrimal canaliculi.

Function
The medial palpebral ligament acts as a tendon for which the orbicularis oculi muscle inserts (Robinson & Stranc, 1970).
