Branch Retinal Artery Occlusion

Branch retinal artery occlusion (BRAO) is acute sectoral visual-field loss due to embolic occlusion of a branch of the central retinal artery. Clinical: sudden monocular sectoral vision loss, with a wedge-shaped retinal infarct and embolus on fundus exam. Treatment: supportive; lower IOP if acute; evaluate and treat embolic source (carotid/cardiac) and vascular risk factors (the same as stroke prevention).

Common Symptoms

Sudden monocular sectoral visual-field loss; wedge retinal infarct; embolus visible

Causes and Pathogenesis

Embolus occludes a branch retinal artery, producing a wedge inner-retinal infarct.

Treatment

Supportive; lower IOP if acute; embolic source/vascular risk workup

Preventive Measures

Control vascular risk; carotid/cardiac evaluation; antiplatelet.
