title: Alterations in retinal nerve fiber layer thickness following indirect traumatic optic neuropathy detected by nerve fiber analyzer, GDx-N.
abstract: OBJECTIVE
  To evaluate changes in the retinal nerve fiber layer following traumatic optic neuropathy.
  
  
  METHODS
  Observational case report.
  
  
  METHODS
  A patient presented with visual loss after an accident. Scanning laser polarimetry was performed.
  
  
  RESULTS
  Thickness of the retinal nerve fiber layer increased immediately after the trauma but then progressively decreased. Severe loss was observed at day 90 and then ceased. Enlargement of the optic disk cup was also observed.
  
  
  CONCLUSIONS
  This is the first report documenting early transient increase followed by progressive loss of the retinal nerve fiber layer in traumatic optic neuropathy.
