The Branch Retinal Artery Occlusion (BRAO) is a condition that occurs when the blood flow through one of the retinal arteries supplying the retina is blocked. This blockage is typically caused by a thrombus or embolus.

Symptoms[edit | edit source]

Patients with BRAO often experience sudden, painless loss of vision in one eye. The extent of visual loss depends on the location and extent of the occlusion.

Causes[edit | edit source]

The most common cause of BRAO is a thrombus or embolus. Other causes include vasculitis, arteriosclerosis, and hypercoagulable states.

Diagnosis[edit | edit source]

Diagnosis of BRAO is typically made through a comprehensive eye examination, including a detailed review of the patient's medical history, visual acuity testing, ophthalmoscopy, and fluorescein angiography.

Treatment[edit | edit source]

Treatment for BRAO aims to restore blood flow to the retina. This may involve medications to dissolve the clot or reduce inflammation, or surgical procedures such as laser photocoagulation or vitrectomy.

Prognosis[edit | edit source]

The prognosis for BRAO varies depending on the extent of the occlusion and the promptness of treatment. Some patients may regain some vision, while others may have permanent visual loss.
