The classical presentation of each CN palsy in isolation will be reviewed. In a CN III (oculomotor nerve) palsy, the affected eye can be deviated downward (hypotropia) and outward (exotropia); this can be accompanied by partial or complete ptosis and possibly pupillary dilation (anisocoria). The ocular motor nerves are cranial nerves three (CNIII), four (CNIV), and six (CNVI), also known as the oculomotor, trochlear, and abducent nerves, respectively. Collectively they supply motor fibers to the extraocular muscles of the globe and levator muscle of the eyelid and parasympathetic pupillomotor fibers to the ciliary ganglion. The purpose of this review is to describe the method to visualize cranial nerves III, IV, and VI and to present the imaging findings of congenital cranial dysinnervation disorders including congenital oculomotor nerve palsy, congenital trochlear nerve palsy, Duane retraction syndrome, Möbius syndrome, congenital fibrosis of the extraocular muscles, synergistic divergence, and synergistic convergence. The causes of paralytic strabismus are deficiencies of cranial nerves III, IV, or VI. When encountering neurogenic diplopia, the clinician must determine which ocular motor nerve is involved. The clinician must then decide whether the disturbance is in the nerve nucleus, its fascicles, along the course of the nerve in the subarachnoid space, in the cavernous sinus, or at its termination within About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.
