Blindness due to lesions in the left and right occipital lobes of the brain. The eyes are still able to move and the pupillary light reflexes remain, but the blindness is as if the optic nerves had been severed. The usual cause is occlusion of the posterior cerebral arteries. Transitory cortical blindness may follow head injury.
