The Branch Retinal Artery is a small blood vessel that supplies oxygen and nutrients to specific areas of the retina, the light-sensitive layer at the back of the eye. It branches off from the central retinal artery and plays a crucial role in maintaining the health and function of the retina. When a Branch Retinal Artery becomes blocked, it can lead to a condition known as branch retinal artery occlusion, which may cause sudden vision loss in the affected area. Early detection and treatment are essential to prevent permanent damage to the retina and preserve vision.
