Clinical Presentation of Pseudo–Abducens Palsy

In Brief Purpose Pseudo–abducens palsy is a neurologic limitation in abduction with an intact abducens nerve. This rare condition can be observed when voluntary eye movements show impairment in lateral gaze, yet the vestibulo-ocular reflex (VOR) demonstrates full abduction. The intact VOR indicates the integrity of the infranuclear abducens nerve, thus suggesting that a pseudo–abducens palsy is likely caused by supranuclear pathology. Case...
