Abstract
|
|
|
|
Optic nerve sheath meningioma is a rare tumor originating from meningothelial cap cells of the arachnoid membrane surrounding the intraorbital optic nerve. Because optic nerve sheath meningioma grows slowly and presents benign clinical behaviors which do not cause death, observation with regular evaluation is usually considered prior to interventional treatment. However, some reports indicated that progressive visual loss in one eye and gradual progression into bilateral involvement with intracranial extension confer blindness of both eyes. Therefore, optimal management should be properly selected to produce superior clinical outcomes with the consideration of the visual function and tumor extent.
