Abducens nerve palsy

Revision as of 08:37, 28 August 2015 by Boghs (talk | contribs) (Differential Diagnosis)


Palsy of the abducens nerve, CN VI, is the most common ocular nerve palsy. The abducens nerve innervates the ipsilateral lateral rectus muscle, controlling eye abduction. A palsy results in an esotropia of the affected eye due to the unopposed action of the medial rectus muscle.

Clinical Features

Patients with a CN VI palsy frequently present with diplopia and esotropia. They may have a head turn to help correct their diplopia.
