Lateral view of the vertical extent of the lateral rectus (LR) insertion across the horizontal globe meridian (dashed black line). Your healthcare provider will probably want to order brain imaging tests because the nerve often becomes compressed as it leaves the brain. Contributions are fully tax-deductible. 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.

This condition results in a VIth nerve palsy with an associated reduction in hearing ipsilaterally, plus facial pain and paralysis, and photophobia. [7], Isolated lesions of the VI nerve nucleus will not give rise to an isolated VIth nerve palsy because paramedian pontine reticular formation fibers pass through the nucleus to the opposite IIIrd nerve nucleus. Lesions in this area can arise as a result of vascular problems, inflammation, metastatic carcinomas and primary meningiomas.
