It affects the function of the sixth cranial (skull) nerve. As a result, the person may have double vision. Causes Cranial mononeuropathy VI is damage to the sixth cranial nerve. This nerve is also called the abducens nerve. It helps you move your eye sideways toward your temple.Disorders of this nerve can occur with:Brain aneurysms AneurysmsAn aneurysm is an abnormal widening or ballooning of a part of an artery due to weakness in the wall of the blood vessel.ImageRead Article Now Book Mark Article Nerve damage from diabetes(diabetic neuropathy) Diabetic neuropathyNerve damage that occurs in people with diabetes is called diabetic neuropathy. This condition is a complication of diabetes.ImageRead Article Now Book Mark Article Gradenigo syndrome (which also causes discharge from the ear and eye pain) Tolosa-Hunt syndrome, inflammation of the area behind the eye Increased or decreased pressure in the skull Infections (such as meningitis or sinusitis) MeningitisMeningitis is an infection of the membranes covering the brain and spinal cord. This covering is called the meninges.ImageRead Article Now Book Mark Article SinusitisSinusitis is present when the tissue lining the sinuses become swollen or inflamed. It occurs as the result of an inflammatory reaction or an infect...ImageRead Article Now Book Mark Article Multiple sclerosis (MS), a disease that affects the brain and spinal cord MSMultiple sclerosis (MS) is an autoimmune disease that affects the brain and spinal cord (central nervous system).ImageRead Article Now Book Mark Article Pregnancy Stroke Trauma (caused by head injury or accidentally during surgery) Tumors around or behind the eye The exact cause of vaccination-related cranial nerve palsy in children is not known.Because there are common nerve pathways through the skull, the same disorder that damages the sixth cranial nerve may affect other cranial nerves (such as the third or fourth cranial nerve). Symptoms When the sixth cranial nerve doesn't work properly, you can't turn your eye outward toward your ear. You can still move your eye up, down, and toward the nose, unless other nerves are affected.Symptoms may include:Double vision when looking to one side Double visionThere are many types of eye problems and vision disturbances, such as: Halos Blurred vision (the loss of sharpness of vision and the inability to see...ImageRead Article Now Book Mark Article Headaches Pain around the eye Exams and Tests Tests often show that one eye has trouble looking to the side while the other eye moves normally. An examination shows the eyes do not line up either at rest or when looking in the direction of the weak eye.Your health care provider will do a complete examination to determine the possible effect on other parts of the nervous system. Depending on the suspected cause, you may need:Blood tests Head imaging study (such as an MRI or CT scan) MRIA head MRI (magnetic resonance imaging) is an imaging test that uses powerful magnets and radio waves to create pictures of the brain and surrounding...ImageRead Article Now Book Mark Article CT scanA head computed tomography (CT) scan uses many x-rays to create pictures of the head, including the skull, brain, eye sockets, and sinuses.ImageRead Article Now Book Mark Article Spinal tap (lumbar puncture) Spinal tapCerebrospinal fluid (CSF) collection is a test to look at the fluid that surrounds the brain and spinal cord. CSF acts as a cushion, protecting the b...ImageRead Article Now Book Mark Article You may need to be referred to a doctor who specializes in vision problems related to the nervous system (neuro-ophthalmologist). Treatment If your provider diagnoses swelling or inflammation of, or around the nerve, medicines called corticosteroids may be used.Sometimes, the condition disappears without treatment. If you have diabetes, you'll be advised to keep tight control of your blood sugar level.Blood sugar levelA blood sugar test measures the amount of a sugar called glucose in a sample of your blood. Glucose is a major source of energy for most cells of the...ImageRead Article Now Book Mark Article The provider may prescribe an eye patch to relieve the double vision. The patch can be removed after the nerve heals.Surgery may be advised if there is no recovery in 6 to 12 months. Outlook (Prognosis) Treating the cause may improve the condition. Recovery often occurs within 3 months in older adults who have hypertension or diabetes. There is less chance of recovery in case of complete paralysis of the sixth nerve. The chances of recovery are less in children than in adults in case of traumatic injury of the nerve. Recovery is usually complete in case of benign sixth nerve palsy in childhood. Possible Complications Complications may include permanent vision changes. When to Contact a Medical Professional Call your provider if you have double vision. Prevention There is no way to prevent this condition. People with diabetes may reduce the risk by controlling their blood sugar.Open ReferencesReferencesMcGee S.
