Ocular extrinsic examination at hospital admission demonstrating complete left oculomotor nerve palsy. (a) Both eyelids closed. (b) Complete ptosis of the left eyelid. (c) The patient looking forward, demonstrating a left rotation of the left eyeball due to abducens nerve function not balanced by the oculomotor nerve stimuli over the medial rectus muscle. (d) The patient looking to the right, without medial movement of the left eyeball. (e) The patient looking upward without superior vertical movement of the left eyeball. (f) The patient looking downward without inferior vertical movement of the left eyeball.

Ocular extrinsic movement of the right eyeball was preserved; however, the superior, inferior, and medial movement of the left eyeball was compromised [Figure 1], and the left pupil constriction due to light stimuli was absent (for both photomotor and consensual tests).
Computed tomography at hospital admission demonstrating subarachnoid hemorrhage on the interpeduncular and ambient cisterns, interhemispheric and lateral fissures, and also in the fourth ventricle.
