Ocular blood vessels are the network of blood vessels that supply the eye with essential nutrients and oxygen. These vessels include arteries, veins, and capillaries, which work together to maintain the health of the eye. The main arteries, such as the central retinal artery, branch from larger vessels to deliver blood to different parts of the eye. The retina, a crucial part of the eye responsible for vision, relies heavily on these blood vessels for its function. Proper blood flow is vital for preventing conditions like diabetic retinopathy and glaucoma, which can lead to vision loss if not managed effectively.
