Fig. 21. Axial view of the eyelids and orbit as seen from above. The anterior reflection of the medial canthal tendon and its position anterior to the lacrimal sac are shown in the medial orbit. The normal direction of the tarsoligamentous sling insertion is posterior. This posterior attachment is at the level of the posterior lacrimal crest. The lateral palpebral ligament or tendon inserts inside the edge of the lateral orbital rim at the tubercle and not at the anterior edge of the rim.
