Optic nerve gliomas are the most frequent neoplasms of the optic nerve. They account for 1% of all intracranial tumors (1). Only 25% of optic gliomas are confined to the optic nerve itself, while in 40-75% of cases optic gliomas involve chiasm, hypothalamus and other structures (2).
They mostly arise as histologically benign tumors during childhood and in young adults. However, a highly aggressive and malignant form of optic glioma can occur in older adults, which often results in blindness and fatal outcome in a relatively short period of time.
