Sixth Nerve Palsy: Causes, Symptoms & Treatment - Cleveland Clinic
Sixth nerve palsy is a condition where damage to a specific nerve disrupts eye movement and alignment. It’s usually one-sided (unilateral) and affects one eye only, but it can sometimes affect both eyes (bilateral). It’s also known as abducens (pronounced “ab-DEW-sens”) nerve palsy. Cleveland Clinic is a non-profit academic medical center.
Abducens Nerve Palsy - EyeWiki
Abducens (sixth cranial) nerve palsy is the most common ocular motor paralysis in adults and the second-most common in children. The abducens nerve controls the lateral rectus muscle, which abducts the eye. Abducens nerve palsy causes an esotropia due to the unopposed action of the antagonistic medial rectus muscle.

Sixth nerve palsy is frequently due to a benign process with full recovery within weeks, yet caution is warranted as it may portend a serious neurologic process. Hence, early diagnosis is often critical for some conditions that present with sixth nerve palsy.
Sixth Nerve Palsy - Cedars-Sinai
Sixth nerve palsy occurs when the sixth cranial nerve is damaged or doesn't work right. It's also known as the abducens nerve. This condition causes problems with eye movement.

2015年10月14日 · Finally, isolated sixth nerve palsies are often accompanied by small (< 5 prism diopter) hypertropias, possibly from asymmetric involvement of the lateral rectus compartments, but the presence of larger hypertropias should prompt consideration of concurrent fourth nerve palsies, skew deviations, or, in children, dissociated vertical deviations.
Sixth nerve palsy - Wikipedia
Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye. [1] .
