Introduction: The purpose of this study is to help the experimental subject with her vision problems. The twelve cranial nerves include the olfactory nerve, optic nerve, oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, vestibulocochlear nerve, glossyopharyngeal nerve, vagus nerve, accessory nerve, and the hypoglossal nerve. Each nerve functions as sensory, motor, or both sensory and motor. Moreover, both the optic nerve and the trigeminal nerve carry sensory information from the eyes to the brain (Marieb & Hoehn, 2014, p.495). Meanwhile, the nerves that carry motor functions from the brain to the eye are the oculomotor …show more content…
First to test the visual acuity, have the experimental subject stand about 20 feet away from a Snellen eye chart and cover one eye. Then have the subject read the letters on the chart starting from the top to the bottom. Record the number next to the lowest readable line. Test both eyes. After that to test the peripheral vision have the subject sit in front of you about 2 feet away. Then tell the subject to look straight ahead and cover one eye. Take a pencil and place it next to the ear on the side of the covered eye to the point where it cannot be seen. Slowly move the pencil in an arc position to the point where it is seen. Estimate and record the angle from the pupil to the pencil. Test both …show more content…
Record the eye movement symmetrical, not symmetrical, not smooth and smooth. o Trigeminal nerve:
To test the motor function of the trigeminal nerve ask the subject to clench their teeth. Then palpate the temporalis muscle. Record if the strength is equal or not. Then have the subject bite down on a tongue depressor with one side and attempt to pull it out. Repeat with other side. Record observations. To test the sensory function of the trigeminal nerve, three different divisions will be tested; the ophthalmic division, the maxillary division, and the mandibular division. Take the Von Frey hair, the cold mall probe, and warm mall probe and test both the right and left side of each division. Record observations. o Abducens nerve:
Have the subject move his eyes left and right. Observe and record observations as symmetrical, not symmetrical, smooth, or not smooth. o Facial
