The occipital pole is the rounded back tip of each cerebral hemisphere. It contains the part of the primary visual cortex that serves central vision from the macula.
| Location | Posterior tip of the occipital lobe, beneath the occipital bone near the inion |

| Blood Supply | Posterior cerebral artery (calcarine branch); Middle cerebral artery (terminal branches) |
Processes detailed central vision.
Because the pole often has a dual blood supply, posterior cerebral artery strokes may spare central vision (macular sparing). A blow to the back of the head can injure the pole and cause central visual field defects.
Loss of half the visual field with central vision preserved after posterior cerebral artery stroke.
