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. CONCLUSION: C-ANCA is an indicator of vasculitis and may be useful as an indicator of severe cat-scratch disease.
