The extraocular muscles. From top to bottom: superior rectus, superior oblique, medial rectus, lateral rectus, inferior rectus, and inferior oblique.

Extraocular muscle paresis, also known as ophthalmoplegia, is a condition characterized by weakness or paralysis of one or more of the extraocular muscles, which control eye movement. This can result in symptoms such as diplopia (double vision), strabismus (misalignment of the eyes), and ptosis (drooping of the upper eyelid).

Causes

Extraocular muscle paresis can be caused by a variety of conditions, including cranial nerve palsy, myasthenia gravis, Graves' disease, and orbital pseudotumor. It can also be a result of trauma or surgery to the eye or orbit.

Diagnosis

Diagnosis of extraocular muscle paresis typically involves a thorough eye examination, including tests of eye movement and alignment. Imaging studies such as MRI or CT scan may also be used to identify any underlying conditions.

Treatment

Treatment for extraocular muscle paresis depends on the underlying cause. This may include medication, surgery, or other interventions to improve eye alignment and reduce symptoms.
