Anatomical Relations
The superior tarsal plate is located in the upper eyelid, its free border is straight and closely related to the eyelash follicles. The border closest to the orbit is convex and attached to the orbital septum. Both tarsal plates are attached to the margin of the orbit via the orbital septum and the medial and lateral palpebral ligaments. Fibers from levator palpebrae superioris attach to the superior tarsus. The superior tarsal muscle is also closely associated.
Function
The superior tarsal plate provides support to the upper eyelid and determines the shape of the eyelid.
