Extraocular muscle function testing

Definition:

Extraocular muscle function testing is an examination of the function of the eye muscles. A doctor observes the movement of the eyes in six specific directions.



Alternative Names:

EOM; Extraocular movement; Ocular motility examination



How the Test is Performed:

You are asked to sit or stand with your head erect and a forward gaze. Your health care provider will hold a pen or other object 12 inches in front of your face. He or she will then move the object in several directions and ask you to follow it with your eyes, without moving your head.



How to Prepare for the Test:

No special preparation is necessary for this test.



How the Test will Feel:

The test involves only normal movement of the eyes.



Why the Test is Performed:

This test is performed to evaluate any weakness or other problem in the extraocular muscles, which may result in double vision or rapid, uncontrolled eye movements .



Normal Results:

Normal movement of the eyes in all directions.



What Abnormal Results Mean:

Eye movement disorders may be due to abnormalities of the muscles themselves or problems in the sections of the brain that control these muscles. Your doctor will discuss any abnormalities identified.



Risks:

There are no risks associated with this test.



Considerations:

Slight nystagmus with an extreme sideways gaze that stops quickly is normal.
