Suspensory ligament of eyeball

The suspensory ligament of the eyeball, also known as Lockwood's ligament, is a crucial structure in the anatomy of the eye. It plays a significant role in supporting the eyeball within the orbit.

Anatomy

The suspensory ligament is a fibrous sheath that extends from the medial rectus muscle to the lateral rectus muscle. It is situated below the eye and helps maintain the position of the eyeball by forming a supportive sling. This ligament is part of the fascia bulbi, which is a connective tissue layer surrounding the eye.

Function

The primary function of the suspensory ligament of the eyeball is to support the eyeball and prevent it from sagging within the orbit. It acts as a hammock, distributing the weight of the eye and maintaining its proper alignment. This is essential for normal ocular function and vision.

Clinical Significance

Damage or weakening of the suspensory ligament can lead to enophthalmos, a condition where the eyeball sinks into the orbit. This can occur due to trauma, aging, or certain diseases. Proper functioning of this ligament is crucial for maintaining ocular health and vision.

Related Structures

The suspensory ligament of the eyeball is closely associated with other structures in the orbit, including the extraocular muscles, the optic nerve, and the lacrimal gland. It works in conjunction with these structures to facilitate eye movement and vision.
