The Orbital Fascia forms the periosteum of the orbit.

It is loosely connected to the bones and can be readily separated from them.

Behind, it is united with the dura mater by processes which pass through the optic foramen and superior orbital fissure, and with the sheath of the optic nerve.

In front, it is connected with the periosteum at the margin of the orbit, and sends off a process which assists in forming the orbital septum.

From it two processes are given off; one to enclose the lacrimal gland, the other to hold the pulley of the Obliquus superior in position.
