Your guide to oculomotor nerve palsy and its treatment


Oculomotor nerve palsy is a nerve condition that affects your vision. This can lead to double vision and difficulty using both eyes together. A weakness in the oculomotor nerves causes this condition, leading to loss of control over important eye muscles.

Sometimes people are born with motor paralysis of the oculomotor nerve. In other cases, the condition results from disease or injury. Treatment depends on the underlying cause, but may include surgery, corrective lenses, or vision therapy.

Oculomotor nerve palsy is any decrease in the strength of the oculomotor nerves. These nerves coordinate the vital muscle movements of your eyes. They help your eyes focus and are responsible for defining your visual field. Eye muscles controlled by the oculomotor nerves include:

  • upper right
  • lower right
  • medial right
  • inferior oblique
  • levator palpebrae superioris

Oculomotor paralysis can affect one or all of these muscles. It can be partial with mild symptoms or complete with severe symptoms.

The causes of paralysis of the oculomotor nerve are multiple. In many cases, the condition is developmental and sometimes present at birth. It can also occur as a result of injury during the birthing process.

When people acquire oculomotor nerve palsy later in life, it can result from many conditions, infections, and injuries. They understand:

Symptoms of oculomotor nerve palsy can depend on the severity and number of muscles affected. Most symptoms are also symptoms of other eye or nerve conditions.

However, it’s always a good idea to contact a medical professional about any symptoms that affect your vision. Many conditions that change your vision can get worse, and early treatment can be important.

Common symptoms of ocular nerve palsy include:

  • Double vision. Oculomotor nerve palsy affects the way your eyes work together. When your eyes cannot work together properly, it can cause double vision.
  • Loss of eye concentration and crossed eyes. It can be difficult to focus your eyes or control the direction of your eye movements when you have oculomotor nerve palsy. Often people with this condition have difficulty moving their eyes in the same direction at the same time.
  • Atypical head movements. People with oculomotor nerve palsy often move their heads to compensate for their weakened eye muscles. This can lead to head movements and postures that may distract you or make you feel uncomfortable.

What does oculomotor nerve palsy look like?

Treatment for oculomotor nerve palsy will depend on the underlying cause and severity. You may need to undergo a series of tests before your doctors can finalize a treatment plan. The tests will help doctors find the exact cause and the muscles involved.

Common treatment options include:

  • Surgery to relieve pressure on the nerve. Doctors often do surgery for a tumor, aneurysm, or non-cancerous growth.
  • Eye muscle surgery. A type of eye surgery called strabismus surgery can help realign the eyes.
  • Temporary eye patches or prism glasses. These visual aids can help manage double vision. You can wear them for 6 months to a year. Sometimes this is enough for the oculomotor nerve palsy to heal on its own.
  • Permanent prism glasses. You can wear prism glasses daily to manage double vision.
  • Visual therapy. Vision therapy is a program that helps strengthen eye muscles to help reduce or eliminate symptoms.

Your coverage will depend on the specific treatment. Medicare or other insurance plans usually don’t include coverage for vision problems. Rarely are treatments such as eye patches, glasses, specialized lenses or vision therapy covered.

However, treatment options, such as surgery to relieve pressure on the eye nerve, may be covered under some plans. For example, although Medicare does not cover treatments such as vision therapy and prismatic lenses, it does cover surgeries that repair eye function.

It’s a good idea to talk with your doctors about any planned treatment ahead of time. You can then call your insurance company to see what coverage they offer.

In many cases, oculomotor nerve palsy disappears within a few months. When this is not the case, options such as glasses with prismatic lenses can help you manage the symptoms in your daily life. Surgical treatments and vision therapy can also reduce symptoms and help improve eye muscle strength.

The underlying cause of your oculomotor nerve palsy affects your range of treatment options and your outlook. For some causes, such as high blood pressure or diabetes, managing those causes can play an important role in improving your outlook.

Oculomotor nerve palsy is a condition that affects the oculomotor nerves in your eyes. This leads to decreased strength and harder control of your eye muscles. This leads to double vision and difficulty focusing your eyes.

Oculomotor nerve palsy can be present at birth or can result from health problems, injuries, or infections. In some cases, oculomotor nerve palsy resolves quickly without intervention. When you need treatment, a combination of surgery, corrective vision aids and vision therapy can help.
