title: [Proliferative retinal vasculitis and multiple sclerosis: a case report].
abstract: BACKGROUND
  Retinal periphlebitis can precede the neurological effects of multiple sclerosis and reveal the disease. Although these occurrences of vasculitis are noted in 10% - 35% of multiple sclerosis patients, proliferative retinopathy is, on the contrary, an exceptional complication.
  
  
  METHODS
  We report the case of a 28-year-old woman who presented bilateral, proliferative, retinal vasculitis complicated with recurrent vitreous hemorrhages occurring with multiple sclerosis. Initially, there was a unilateral, central venous thrombosis in a particularly ischemic and proliferative form. After a neurological, biological and radiological check-up, the diagnosis of multiple sclerosis was pronounced and treatment with Interferon was started. A pan-retinal laser photocoagulation and vitrectomy with proliferative membrane peeling were performed. After a follow-up of 2.5 years, a bilateral epiretinal membrane on the macula with a chronic macular edema persisted, with visual acuity limited to 0.2 Parinaud 4 in the right eye and 0.5 Parinaud 2 in the left eye.
  
  
  CONCLUSIONS
  This case shows that the diagnosis of multiple sclerosis must be established in cases of ischemic retinal vasculitis, especially as the literature does not seem to report a correlation between the retinal vascular affect and how far multiple sclerosis has progressed. Moreover, the visual prognosis of these proliferative lesions remains uncertain.
  
  
  CONCLUSIONS
  Multiple sclerosis can be revealed initially, although exceptionally, by bilateral, proliferative and severe retinal vasculitis complicated with recurrent vitreous hemorrhages and tractional retinal detachment.
