Glass artery of the eye? Why is this? If you meant the Vitreous Artery, then it is a vessel that is fed by blood from the Aorta, internal carotid artery or arch of the Aoa and delivered to the middle ear and ocular structures such as the vitreous. This artery can have different names, but the most common is the artery of the Vitreous Body. It has a complex structure and branches into many branches that nourish the eye structures.
