WebCNVI palsy resolved in 50% of the cases, with an average time to resolution of 6 weeks (range, 2-12 weeks). As the VIth nerve passes through the subarachnoid space it lies adjacent to anterior inferior and posterior inferior cerebellar and basilar arteries and is therefore vulnerable to compression against the clivus. The sole function of the sixth cranial nerve is to innervate the lateral rectus muscle, so the hallmark of a sixth nerve palsy is weakness of the lateral rectus. The VIth nerve's course is short and lesions in the orbit rarely give rise to isolated VIth nerve palsies, but more typically involve one or more of the other extraocular muscle groups.
