Dissection of left orbit from an anterior approach
Insertion of levator palpebrae superioris muscle
The orbicularis oculi muscle has been incised vertically and retracted to expose deeper structures in the upper eyelid. The insertion of the aponeurosis of the levator palpebrae superioris muscle into the deep surface of the orbicularis oculi muscle is visible at 16. Some of the fibers of this aponeurosis continue to insert into the skin of the eyelid. A thin layer of fascia covers the tarsal plate (18).
