Primary optic nerve neoplasms are less common than secondary involvement of optic nerve by direct invasion from extension of intraocular malignancies. Here we present11cases originated primarily in optic nerve and its contents. We had 1.42% cases of primary optic nerve tumors among all operated cases of CNS tumors. Primary optic nerve tumors include pilocytic astrocytoma (5cases) & a case of pilomyxoid astrocytoma occurring in children. Among the primary optic nerve sheath tumors, meningioma (2cases) was most common along with one case each of schwannoma and AV hemangioma. Meningioma was seen in middle to elderly females while schwannoma in young adult. Primary optic nerve tumor presents with overlapping clinical and radiological manifestation. Hence intraoperative squash smear cytology can be used effectively to give preliminary diagnosis, as it is fairly accurate & established technique for diagnosis. Visual outcome of patients with primary optic nerve tumors depends on the type of the lesion which can be done by confirmative histopathology only.
