Palsies of Cranial Nerves That Control Eye MovementMichael Rubin, MDCM
During clinical examination, bitemporal field defects are noted and, in the case of associated optic nerve injury, there will be a visual loss in the involved eye. Funduscopic examination also reveals pallor of the optic disc on the nasal side. Other cranial nerves may be involved in a ...
Your cranial nerves are imperative to how your neck, head, and face function. Anydamage to these 12 nervescould have a great impact on your day-to-day life. The majority of these nerves can be found at the surface level of your skull, which means they’re very susceptible to injury bec...
Cranial nerves III, IV and V are motor nerves and are responsible for the movement of the human eye. CN III, better known as the oculomotor nerve, is perhaps the most important of the three. The oculomotor nerves originate in the oculomotor nucleus in the midbrain and separate into superior...
3,20 Sarcoidosis involvement of cranial nerves II and VIII can be fairly refractory to treatment and cause much functional impairment for the patient. Bilateral cranial nerve VII and VIII dysfunction is suggestive of CNS sarcoidosis in the proper setting. Trigeminal neuropathies are associated with ...
Along with the oculomotor nerve (CN III) and the trochlear nerve (CN IV), it is a purely motor nerve responsible for controlling movement of the eyeball. Similar to oculomotor and trochlear nerves, the abducens nerve attributes its name to its function. It supplies the muscle (lateral rectus...
Repeat process for other eye. 3. Cranial Nerves II and III. Pupillary light reflex controls the diameter of the pupil in response to the light intensity. Both cranial nerves II and III are being tested when the pupillary response is checked, as the optic nerve carries the afferent fibers ...

Identify the cranial nerves that control the eye, and vision? Which cranial nerve carries sensory signals from the greatest area of the face? Cranial Nerve: The optic cranial nerve is the sensory nerve that receives senses from the...
