Abducens (sixth cranial) nerve palsy is the most common ocular motor paralysis in adults and the second-most common in children. The abducens nerve controls the lateral rectus muscle, which abducts the eye. Abducens nerve palsy causes an esotropia due to the unopposed action of the antagonistic medial rectus muscle.
Sixth nerve palsy occurs when the sixth cranial nerve is damaged or doesn't work right. It's also known as the abducens nerve. This condition causes problems with eye movement. The sixth cranial nerve sends signals to your lateral rectus muscle. This is a small muscle that attaches to the outer side of your eye.
Sixth nerve palsy is also known as lateral rectus palsy. Palsy is a type of full or partial paralysis. Your lateral rectus muscle is one of seven eye muscles located outside your eye. Each muscle moves the eye in one specific direction. The eye muscles work together to allow your eye to move in every direction.
The abducens nerve is a purely somatic motor nerve, It has no sensory function. It innervates the lateral rectus muscle, an extraocular muscles of the eye, which is responsible for the abduction of the eyes on the same (ipsilateral) side.
Causes include an aneurysm, carcinomatous meningitis, procedure-related injury (e.g., spinal anesthesia, post-lumbar puncture), inflammatory lesions (e.g., sarcoid, lupus), infection (e.g., Lyme disease, syphilis, tuberculosis, Cryptococcus).
A complete third nerve palsy causes a completely closed eyelid and deviation of the eye outward and downward. The eye cannot move inward or up, and the pupil is typically enlarged and does not react normally to light.
Fourth nerve palsy means that a certain muscle in your eye is paralyzed. It is caused by disease or injury to the fourth cranial nerve. In children, it is most often present at birth (congenital). In adults, it is most often caused by injury. Many cases of fourth nerve palsy are idiopathic.
This nerve controls movement and sensation in the arm and hand and extension of the elbow, wrist and fingers. Radial nerve palsy is a condition that affects the radial nerve and if damage to this nerve occurs, weakness, numbness and an inability to control the muscles served by this nerve may result.
Unilateral isolated medial rectus nuclear palsy can be the only manifestation of midbrain infarction. Systematic clinical approach with appropriate history and physical examination is essential to elucidate the etiology of diplopia and to avoid missing a serious underlying diagnosis, such as cerebrovascular accidents.
orbital cavityThe lateral rectus muscle originates in the bottom of the orbital cavity in the surrounding area of the optic canal, specifically in the lateral part of the common tendinous ring; the annulus of Zinn.
The medial rectus is an adductor, and functions along with the lateral rectus which abducts the eye. These two muscles allow the eyes to move from side to side. With the head facing straight and the eyes facing straight ahead, the eyes are said to be in primary gaze.
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. The inability of an eye to turn outward results in a convergent strabismus or esotropia of which the primary symptom is double vision or diplopia in which the two images appear side-by-side. The condition is commonly unilateral but can also occur bilaterally.
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code H49.21 and a single ICD9 code, 378.54 is an approximate match for comparison and conversion purposes.
