View image. The optic nerve connects your eyes to your brain. It carries the visual messages that you see to your brain. An injury to your optic nerve is called traumatic optic neuropathy. If your injury is severe, you may have permanent changes in your vision.
The trigeminal nerve (CN V) supplies sensory fibers to the face and motor fibers to the muscles of mastication. Touching or pinching the face causes a behavioral reaction in most animals, indicating intact sensation (see nasal stimulation). The sensory fibers for the palpebral and corneal reflexes are in CN V. The three branches of this CN (ophthalmic, maxillary and mandibular) should all be tested. Touching the medial canthus of the eye evaluates the ophthalmic branch. Touching the lateral canthus of the eye evaluates the maxillary branch.
