The authors discuss their experience with 11 cases of intraorbital meningioma, revealing how computed tomography scanning has aided in early diagnosis of primary optic nerve meningiomas. Despite the difficulty of removing apical, primary optic nerve meningioma without sacrificing the central retinal artery, the authors prefer a surgical approach backed up by radiation therapy. It appears that general improvement, although generally elusive, is worth the risk incurred in trying to overcome the deficits stemming from these tumors.
