Depending on its location and severity, a TBI can affect your vision by damaging parts of the brain involved in visual processing and/or perception (e.g., cranial nerves, optic nerve tract or other circuitry involved in vision, occipital lobe).
Occipital lobe â a small region located at the back of the head. The occipital lobe is responsible for integration of vision. Temporal lobe â located at the side of the head above the ears and below the frontal lobe. The temporal lobe controls hearing, memory, speech, and comprehension.
