sixth nerve palsy

Those with sixth nerve palsy therefore experience horizontal double vision which is worse when looking towards the affected side.

Sixth nerve palsy is the most common.

Isolated sixth nerve palsies in children are assumed to be due to brain tumors until proven otherwise.

Sixth nerve palsies are infamous as "false localizing signs."

Thus a right-sided sixth nerve palsy does not necessarily imply a right-sided cause.

A right-sided brain tumor can produce either a right-sided or a left-sided sixth nerve palsy as an initial sign.

Grade 2: Moderate to severe headache; nuchal rigidity; no neurologic deficit except sixth nerve palsy.

Sixth nerve palsy - Abducens nerve (VI)

Damage to the abducens nucleus does not produce an isolated sixth nerve palsy, but rather a horizontal gaze palsy that affects both eyes simultaneously.

If there are cranial nerve abnormalities, these may be noticed on eye examination in the form of a squint (third, fourth, or sixth nerve palsy) or as facial nerve palsy.

Suspicion for myopathies should be increased in patients whose ophthalmoplegia does not match a particular set of cranial nerve palsies (oculomotor nerve palsy, fourth nerve palsy, sixth nerve palsy).

Paralytic strabismus has many causes including Oculomotor nerve palsy, Fourth nerve palsy, Congenital fourth nerve palsy, Sixth nerve palsy, Progressive external ophthalmoplegia, and Kearns-Sayre syndrome.

Sixth nerve palsy: In an adult, new-onset sixth nerve palsy will result in double vision, but congenital sixth nerve palsy will lead to amblyopia.

Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for contracting the lateral rectus muscle to abduct (i.e., turn out) the eye.
