Abstract: The oculomotor nerve is the cranial nerve responsible for innervating the superior, inferior, and medial recti. It functions to rotate the eye medially, upwards, and downwards while also being responsible for elevating the upper eyelid. The nerve tract can be described with five segments: the nucleus, fascicles, subarachnoid cistern, cavernous sinus, and intra-orbital segments. Injury to the oculomotor nerve can happen anywhere along this tract. The four mechanisms of injury that lead to oculomotor nerve palsy are sudden displacement, gradual displacement, ischemia, and direct involvement.
