title: An ocular cat-scratch disease patient positive for cytoplasmic anti-neutrophil cytoplasmic antibody.
abstract: BACKGROUND
  We report a case of ocular cat-scratch disease with permanent vision reduction in a patient who was cytoplasmic anti-neutrophil cytoplasmic antibody (C-ANCA) positive.
  
  
  METHODS
  Case report and review of the literature.
  
  
  RESULTS
  While taking steroids and antibiotics, a 52-year-old man with uveitis associated with cat-scratch disease developed retinal vein occlusion and a macular exudate. His final visual acuity was poor because of residual macular degeneration and optic atrophy. Serum C-ANCA increased and decreased in parallel with ocular inflammatory activity.
  
  
  CONCLUSIONS
  C-ANCA is an indicator of vasculitis and may be useful as an indicator of severe cat-scratch disease.
