RETINAL VASCULAR DISEASES

Branch Retinal Vein Occlusion

Branch retinal vein occlusion is characterized by dilation and tortuosity of the affected vein associated with retinal hemorrhages, cotton-wool spots, and edema in the area drained by the vein.

It is usually caused by a thrombus at arteriovenous crossings where a thickened artery compresses the underlying venous wall.

The complications of branch vein occlusion that are most common and potentially vision-limiting include macular edema and retinal neovascularization.

Differential Diagnosis

  • Diabetic retinopathy
  • Hypertensive retinopathy
  • Leukemic retinopathy
  • Ocular ischemic syndrome
  • Papilledema
  • Retinopathy of anemia
  • Venous stasis retinopathy
