Purpose: To describe an unusual case of optic nerve sheath meningioma presenting as neovascular glaucoma with opto-ciliary shunt vessels. Methods: Clinical case report. Results: We describe the case of a 52 year old man evaluated for markedly elevated intraocular pressure on the basis of neovascular glaucoma with opto-ciliary shunt vessels in that eye, with total optic atrophy present bilaterally. MRI scan of the brain and orbits was prompted by the fundoscopic finding in the setting of history of bilateral visual loss in childhood, prior to the advent of CT or MR imaging, with a negative evaluation then including arteriography, pneumo-encephelography and exploratory craniotomy. The MRI suggested bilateral optic nerve sheath meningiomas, i.e. the "impossible meningioma." Conclusions: The possibility of underlying optic tumor (i.e. optic nerve sheath meningioma)may require consideration as the basis for neovascular glaucoma when the etiology is unclear.
