"Ocular or optic refers specifically to the globe (eyeball). Orbital refers to all the contents of the bony orbit, encompassing both the intra and extraocular structures."

"Over the lateral rectus, the tubular prolongation is thickened to form the lateral check ligament, which attaches to the marginal tubercle of Whitnall (bony elevation at the orbital surface of the zygoma). Over the medial rectus, this prolongation is thickened to form the medial check ligament, which attaches to the posterior lacrimal crest (of the lacrimal bone). Between these ligaments, the inferior part of the sheath is thickened to form the suspensory ligament of Lockwood, which supports the eye within the orbit."

"The orbit has a roof, floor, medial and lateral wall. The orbit is open anteriorly where it is bound by the orbital septum, which forms part of the eyelids. Posteriorly, the orbit angles inward such that their apices communicate with the intracranial compartment via the optic canal and superior orbital fissure."

"The fascial sheath of the eye (Tenon fascia), orbital fat, obliques and bony attachment of the recti provide stability to the eyeball within the orbit and prevent it from sinking or retracting. See article titled 'stability of the eye'."
"There are many nerves within the orbit: see orbital nerve supply."
