Superior transverse ligament of eyeball

The superior transverse ligament of the eye (Whitnall's ligament) is formed by a collection of levator muscle sheaths at the level of aponeurotic change of the levator muscle, attaches to the muscle sheath surrounding the tendon of the superior rectus muscle and the medial side of the trochlea and to the lateral orbital margin medial to the orbital lobe of the lacrimal gland (so the Whitnall's ligament is not attached to the lateral orbital tubercle of Whitnall).

The superior transverse ligamentsupports the upper eyelid, lacrimal gland, and superior orbit, and serves as an anatomical landmark for the superior border of the levator aponeurosis.
