Branch Retinal Vein Occlusion

Statistics and Associations

  • Obstruction of the retinal venous drainage system usually due to a hardened artery pressing on a retinal vein
  • Associated high blood pressure (60%), Glaucoma (40%), Diabetes, Heart Disease, rarely Hypercoagulable States (conditions that cause blood to be thicker than normal)
  • 50% will have Macular edema, 20% will develop epiretinal membranes
  • 50% will have better than 20/40 visual acuity


  • Medical evaluation with attention to cardiovascular system to treat underlying cause
  • If macular involvement, intraocular injection of anti-VEGF agent.
  • New blood vessel growth may require laser treatment
