Dissection of left orbit from a lateral approach
Eye sectioned vertically, optic nerve and papilla
The eye has been sectioned in a parasagittal plane and the optic sheath partially resected. The inferior division of the oculomotor nerve(17) has been preserved. Other nerves which enter the orbit have been transected. The left internal carotid artery is visible withing the cavernous sinus.
