Fractionated gamma knife radiosurgery for optic nerve tumors: a technical report.
OBJECTIVE
The main purpose of this report is to demonstrate the effects of fractionated radiosurgery regimens in the management of optic gliomas MATERIALS and


METHODS
Two patients suffering from progressive loss of vision due to optic nerve gliomas were treated with Gamma Knife radiosurgery in three fractions within three consecutive days instead of a single dose regimen. Patients were followed for 42 and 39 months respectively.


RESULTS
The treatment modality was well tolerated by the patients with radiological and neurological tumor control after 42 and 39 months of follow up. There were no additional complications.


CONCLUSIONS
Fractionated regimens of Gamma Knife surgery offer a very good alternative for lesions such as optic glioma and optic nevre sheath meningioma.
