What is extraocular movement test?
The extraocular muscle function test is performed to evaluate any weakness, or other defect in the extraocular muscles which results in uncontrolled eye movements. The test involves moving the eyes in six different directions in space to evaluate the proper functioning of the extraocular muscles of the eyes.
What test assesses extraocular muscles?
The extraocular muscle function test is performed to evaluate any weakness, or other defect in the extraocular muscles which results in uncontrolled eye movements. The test involves moving the eyes in eight different directions in space to evaluate the proper functioning of the extraocular muscles of the eyes.
What is the purpose of ocular motility test?
The ocular motility test is able to detect any difference in how the eyes are aligned at different positions of gaze and is an essential part of any binocular vision assessment.
How do you test for ophthalmoplegia?
Ophthalmoplegia can be diagnosed with a physical examination to check eye movements. Then an MRI or CT scan may be used to study the eye more closely. Blood tests may be necessary to determine whether it’s being caused by another condition, such as thyroid disease.
How do you do the eye movement test?
The test itself is simple. Your eye healthcare provider or technician will ask you to sit up straight while you stare at an object in front of you, which is usually a pen, fixation light, or small picture held 12 and 16 inches away.
