Transcranial enucleation for optic nerve tumor

Tumors involving both the eye and the optic nerve present a special surgical problem. Conventional enucleation techniques neither permit the surgical exploration of the optic nerve nor assure the complete removal of tumor within the orbit, and they often involve transection through tumor-containing tissue. Transcranial enucleation permits the inspection of the tumor from the back of the globe to the chiasm and its en bloc removal.
