The suspensory ligament of eyeball (or Lockwood's ligament) forms a hammock stretching below the eyeball between the medial and lateral check ligaments and enclosing the inferior rectus and inferior oblique muscles of the eye.
It is a thickening of Tenon's capsule, the dense connective tissue capsule surrounding the globe and separating it from orbital fat.
[1] This ligament is responsible for maintaining and supporting the position of the eyeball in its normal upward and forward position within the orbit, and prevents downward displacement of the eyeball.
[3] It is named for Charles Barrett Lockwood.
