title: [Ocular involvement in polyarteritis nodosa: two cases].
abstract: BACKGROUND
  Polyarteritis nodosa (PAN) is a systemic vasculitis with polymorphic manifestations. Ocular involvement is rare; we report two such cases.
  
  
  METHODS
  The first case was a 56-year-old man with PAN treated with corticosteroids. A year and a half later, during a disease outbreak associated with decreased visual acuity, ocular examination objectified a localized pigment epithelial detachment in the right eye. The outcome was favorable with corticoid bolus followed by azathioprine. The second case was a 41-year-old man presenting with PAN and decreased visual acuity. Ophthalmologic examination showed inferotemporal branch vein occlusion in the right eye with serous retinal detachments in the left eye. The outcome was favorable with intravenous cyclophosphamide followed by azathioprine.
  
  
  CONCLUSIONS
  The incidence of ocular involvement in PAN varies from 10 to 20%. It is most often associated with vasculitis of retinal and choroidal arteries. Fluorescein angiography is the gold standard of diagnosis. Multifocal acute ischemia of the choriocapillaris is very pathognomonic. Immunosuppressant drugs are effective and should be reserved for severe forms.
