Intraconal orbital compartment

Last revised by Craig Hacking on 15 Feb 2024

The intraconal orbital compartment or intraconal space is the conical space within the orbit and musculofascial cone, the base of which is anterior and is formed by the posterior half of the globe. The sides are formed by the extraocular muscles and their surrounding fascia which pass posteriorly and converge on the tendinous ring at the orbital apex. External to this space is the extraconal space.
