Branch Retinal Vein Occlusion (BRVO)

  • Together with CRVO is the second most common cause of retinal vascular disturbance.
  • Commonly occurs in elderly and/or as a manifestatioin of hypertensive retinopathy.
  • Clinical features:
    • Symptoms: various degree of decreased vision
    • Signs:
      • More often occurs at the arteriovenous intersection in the superotemporal quadrant
      • Segmental intraretinal hemorrhage can be easily observed in acute phase
      • The proximal tip of the hemorrhage is usually the proximate location of the occluded vein
      • Cotton wool spots
      • Retinal edema
      • Commonly present with subretinal or vitreous hemorrhage
      • Occasionally associated with cystoid macular edema
      • Dilated and increased tortuosity of the branched vein distal to the occlusion in the chronic phase
      • The presence of collateral vessels around the involved segment can be observed in chronic BRVO
  • Treatment: Laser photocoagulation in selected cases.
