Branch Retinal Artery Occlusion (BRAO)


Branch retinal artery occlusion (BRAO) is a condition characterized by the sudden blockage of one of the small arteries that supply blood to the retina. This blockage, often caused by a blood clot or embolus, leads to reduced blood flow and oxygen supply to the affected area of the retina, resulting in sudden vision loss or visual disturbances in the corresponding part of the visual field.
