As these blood vessels swell, they narrow, which limits the amount of blood they can carry. A lack of blood is called ischemia. Too little enough blood can damage your eyes and cause sudden vision loss. Blindness in GCA is primarily due to ischemic optic neuropathy (ION), where the optic nerve becomes damaged.
