The tissue damage in individual hypersensitivity reactions is often caused by a mixture of the types of hypersensitivity reaction, for example, a combination of types I and IVa. IVb and IVc in contact hypersensitivity.
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).
The cerebral cortex is divided into lobes that each have a specific function. For example, there are specific areas involved in movement and in sensory processes such as vision, hearing, somatosensory perception (touch), and olfaction (smelling). Other areas are critical for thinking and reasoning.
