title: Hemiretinal vein occlusion associated with membranous glomerulonephritis.
abstract: OBJECTIVE
  To report a patient in whom the finding of hemiretinal vein occlusion led to the diagnosis of membranous glomerulonephritis.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  A 44-year-old tennis instructor presented with a 1-week history of blurred vision in the left eye. Examination of the left eye demonstrated a best-corrected visual acuity of 20/40 and an inferior hemiretinal vein occlusion.
  
  
  RESULTS
  Blood pressure was normal, and the patient was referred for a medical examination, which revealed membranous glomerulonephritis. The patient was treated with oral prednisone and cyclosporine. Four months after presentation, the left eye demonstrated resolution of the vascular abnormalities and had a best-corrected visual acuity of 20/20.
  
  
  CONCLUSIONS
  Retinal vein occlusion may be associated with membranous glomerulonephritis. Treatment of the systemic disease may be associated with regression of the retinal vascular abnormalities.
