ABSTRACT
Intrinsic tumors of the optic nerve include optic gliomas and optic sheath meningiomas. Together, they account for less than 4% of all orbital tumors, with optic gliomas representing approximately 65% and meningioma 35% of this group (1). Despite the large literature that has accumulated concerning anterior visual pathway gliomas, there is still considerable controversy regarding their natural history and appropriate management (2).
