En bloc excision of optic nerve sheath meningioma of the orbit preserves the eyeball and ocular motility when the tumor has not spread beyond the orbit

A 53 year old lady presented with gradually progressive proptosis of the left eye and complete vision loss. Imaging was suggestive of optic nerve sheath meningioma confined to the orbit with no intracranial component. Total excision of the tumor along with the optic nerve was performed, sparing the eyeball. At two years follow up the patient was disease free with good ocular motility. En bloc excision is a good option compared to exenteration in intraorbital optic nerve sheath meningiomas with preservation of the eyeball and ensuring good cosmesis.
