Strabismus is a common binocular vision condition in children and adults. It can be a primary diagnosis or secondary from a neurological disease or trauma. Optometrists need to understand how to accurately and efficiently diagnose and manage these patients. Treatment options include, spectacles, prism, vision therapy, or referral for surgical correction. Through the use of clinical cases the course will review the possible causes of strabismus, how to differentiate commitant from non-commitant deviations, and what treatment options are available.
