Clinical InformationClinical

  • Exotropia

    a form of ocular misalignment where the visual axes diverge inappropriately. for example, medial rectus muscle weakness may produce this condition as the affected eye will deviate laterally upon attempted forward gaze. an exotropia occurs due to the relatively unopposed force exerted on the eye by the lateral rectus muscle, which pulls the eye in an outward direction.

Patient EducationClinical

Eye Movement Disorders

When you look at an object, you're using several muscles to move both eyes to focus on it. If you have a problem with the muscles, the eyes don't work properly.
