Abducens nerve palsy

Last revised by Dr Ayla Al Kabbani on 29 Apr 2021

Abducens nerve palsy, or sixth nerve palsy, results in weakness of the ipsilateral lateral rectus muscle.

Patients present with horizontal diplopia with an inability to abduct the ipsilateral eye, thereby resulting in an esotropia (nasal deviation of the eye).

The abducens nerve has the longest subarachnoid course of all the cranial nerves.
