[Traumatic bilateral paralysis of the abducens nerve without cervical fracture]

Abstract

We report the case of a 75-year-old woman with an uneventful medical history who presented with sudden-onset diplopia immediately after neck trauma in a traffic accident. Clinical and ophthalmological examinations were consistent with bilateral abducens nerve palsy. The causal relationship, including the medicolegal implications and the pathophysiological mechanism are discussed. The case demonstrates that exceptionally benign trauma can cause severe diplopia. The delay to recovery may be very long, suggesting caution concerning the decision of surgical care.
