An artery that branches from the ophthalmic artery and enters the retina through the optic nerve. It supplies blood (via the retinal arterioles) to the inner two thirds of the retina.
The retinal arteriolar system originates from a subsidiary division of the ophthalmic artery, responsible for nourishing the intricate network of blood vessels within the retina. These arterial branches intricately extend to form the arterioles that intricately permeate the retinal tissue, ensuring an adequate supply of oxygen and nutrients to support its vital functions.
