Extraconal orbital compartment

The extraconal orbital compartment or extraconal space is the space within the orbit outside the musculofascial cone. The base of which is anterior and is formed by the orbital septum that surrounds the equator of the globe. The external sides are formed by the bones of the orbit and their periosteum. The internal sides are formed by the extraocular muscles and their surrounding fascia which pass posteriorly and converge on the tendinous ring at the orbital apex. Internal to this space is the intraconal space.
