title: [Treatment of congenital jerky nystagmus with opposite bidirectional neutral zone].
abstract: OBJECTIVE
  To explore a method for the treatment of congenital jerky nystagmus with opposite bidirectional neutral zones.
  
  
  METHODS
  The relatively used side between the two neutral zone was found by neutralizing bilateral head torsion angle with prisms. The surgical intervention was indicated for those patients whose head position would not turn to another side.
  
  
  RESULTS
  There were 14 cases treated by this method, none of these cases whose head position turned to another side. Ten cases underwent once operation, 2 cases, twice operations and another 2 cases undertook once operation with additional prism correction. The compensatory head posture was corrected and the vision in the primary position of gaze was improved in all the cases.
  
  
  CONCLUSIONS
  This therapy for congenital jerky nystagmus with opposite bidirectional neutral zone shows significant therapeutic effects and can be available for clinical application.
