The suspensory ligament of the eyeball (Lockwood ligament) is a hammock-like fascial condensation running from the medial to lateral orbital walls beneath the globe, supporting the eyeball within the orbit.
Provides the primary mechanical support for the globe, preventing inferior displacement. Acts as a sling that distributes the weight of the eye across the medial and lateral orbital walls via its attachments to the check ligaments.
Lockwood ligament disruption in orbital floor blowout fractures allows globe ptosis (enophthalmos). In maxillary resection and orbital floor surgery, preservation of Lockwood ligament prevents post-operative globe displacement. Inferior approach orbital surgery must identify and preserve this structure.
Orbital floor fracture disrupting the inferior support system producing globe ptosis and enophthalmos, requiring orbital floor plate reconstruction to restore support.
Inferior globe displacement from Lockwood ligament laxity in silent sinus syndrome or maxillary sinus collapse producing hypoglobus and diplopia.
