Central Retinal Vein Occlusion

Statistics and Associations

  • Obstruction of the retinal venous drainage system usually due to a hardened artery pressing on the central retinal vein
  • Associated high blood pressure (60%), Glaucoma (40%), Diabetes, Heart Disease, rarely Hypercoagulable States (conditions that cause blood to be thicker than normal)
  • Major complications include new blood vessel growth and macular swelling


  • Medical evaluation with attention to cardiovascular system to treat underlying cause
  • Ocular injection of anti-VEGF agent now standard of care
  • Gonioscopy at each visit
  • New blood vessel growth may require laser treatment
