Optic pathway anatomy
WebOptic nerve orientation changes over its course and is consistently oblique to the standard axial, sagittal, and coronal planes of conventional MRI. The nerve is not simply a cylinder extending from globe to chiasm but is composed of 2 obliquely-oriented parts that taper and form a pivot at the orbital apex.
