Retrobulbar meningiomas may be originated from a secondary extension of an intracranial neoplasm through the optic nerve or as a primary orbital tumor, from the arachnoid cells of the intraorbital optic nerve sheath (CHOW & MILES, 1991).
Results of the CT imaging showed a soft-tissue attenuating, peripherally contrast-enhancing mass extending from the right infraorbital sinus to the right retrobulbar space, measuring 2.5 x 1.8 cm.

(4,12) In addition, the literature includes reports of a patient under systemic steroid therapy for "retrobulbar neuritis" developing multiple areas of serous retinal detachment in both eyes and a patient misdiagnosed with Vogt-Koyanagi-Harada disease and treated with corticosteroids who actually had atypical bullous CSCR.
It has a volume of approximately 30 ml, within which the globe, fat, extraocular muscles, vessels, nerves, lacrimal gland, lacrimal sac, and retrobulbar contents are encased within complex fascial compartments.[30],[31] The globe is limited anteriorly by the orbital septum, eyelids, and by the attachment of the medial and lateral canthal tendons.[29],[31]
If the retrobulbar pressure progresses, especially at the orbital apex, there is the risk of the optic nerve becoming compromised causing posterior optic neuropathy, which, if not " identified and treated, can lead to irreversible sight loss.
It may also cause transient increase in intraocular pressure and changes in retrobulbar blood flow (13-15).
