title: Bilateral sixth nerve palsy associated with MDMA ("ecstasy") abuse.
abstract: OBJECTIVE
  To report the association of methylenedioxymetamphetamine (MDMA, "ecstasy") abuse and bilateral sixth nerve palsy.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  A 17-year-old male presented with horizontal diplopia in all directions of gaze after having taken MDMA tablets at 5-day to 7-day intervals during a 2-month period. Examination showed bilateral sixth nerve palsy. Ocular motility returned to normal within 5 days without use of MDMA and with no other treatment.
  
  
  CONCLUSIONS
  Methylenedioxymetamphetamine "ecstasy" abuse should be considered in the differential diagnosis in otherwise unexplained sixth nerve palsy.
