Cortical blindness is the total or partial loss of vision in a normal-appearing eye caused by damage to the visual area in the brain's occipital cortex. This damage is most often caused by loss of blood flow to the occipital cortex from either unilateral or bilateral posterior cerebral artery blockage (ischemic stroke). A patient with cortical blindness often has little or no insight that they have lost vision, a phenomenon known as Anton's Syndrome or Anton-Babinski syndrome.
