title: Ischemic retinopathy associated with Crohn's disease.
abstract: OBJECTIVE
  To report a case of a patient with ischemic retinopathy associated with Crohn's disease.
  
  
  METHODS
  This report presents a case of a 28-year-old female patient with Crohn's disease and sudden decrease of visual acuity in the right eye. Fluorescein angiography, optical coherence tomography, and multifocal electroretinography confirmed the clinical features of ischemic retinopathy. After systemic corticosteroid treatment, the patient developed epiretinal membrane without significant improvement in visual acuity.
  
  
  CONCLUSIONS
  The patient presented with ischemic retinopathy associated with Crohn's disease with deficiency of central visual acuity. Periodic examination by a retina specialist is recommended for patients being treated for Crohn's disease.
