ABSTRACT
Meningiomas and other tumors arising from the optic nerve often present with progressive visual deficits, which may be indolent in the case of meningioma. Treatment with radiotherapy is often indicated for tumor control and visual preservation. Since the tumor is usually small and is located in close proximity to many radiosensitive and critical structures, the technique of stereotactic irradiation is ideal for the delivery of a finely focused beam of radiation to the tumor with maximal sparing of adjacent normal tissue.
