Frequently Asked Questions

What cranial nerve is damaged?

If any of the three cranial nerves that control eye movement (3rd, 4th, or 6th cranial nerve) is damaged, people cannot move their eyes normally. Symptoms include double vision when looking in certain directions. If the 3rd cranial nerve (oculomotor nerve) is paralyzed, the upper eyelid is paralyzed.

What cranial nerve is responsible for moving the eye laterally?

Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye.

What cranial nerve was impaired?

Cranial Nerve. Cranial nerve disease is an impaired functioning of one of the twelve cranial nerves. Each cranial nerve controls functions like smell, vision and balance. Disorders include trigeminal neuralgia, acoustic neuroma, hemifacial spasm, facial nerve disorder and intractable vertigo.

Which cranial nerve causes double vision?

Because each eye has its own lateral rectus muscle and sixth cranial nerve, sixth nerve palsy can affect one or both eyes. Your symptoms and the severity of the condition depend on whether both eyes are affected. Double vision is the most common symptom of sixth nerve palsy.
