Background: Intermittent exotropia is a condition in which part of the times when one eye has drifted outwards, and other times when the eyes are straight. Some patients or family members notice the exotropia more when the patient is tired or daydreaming. Prevalence of basic exotropia accounts for approximately 50% of all intermittent exotropias. Practionor view treating these patients, especially adults with childhood-onset exotropia, as challenging. Contradictory opinions still exist regarding prescribing any treatment for adult strabismus, including surgical realignment and optometric Binocular vision therapy (BVT). Case reports: An adult patients with moderate-size intermittent exotropia of the basic type who presented with asthenopia, headaches, and diplopia. 10 to 20 in-office BVT sessions were endorsed to reduce the magnitude and frequency of the deviation as well as improve their binocularity and decrease their symptoms. After completing OBT, patients became orthotropic for all distances, had normal fuional vergence ability, and had normal near points of convergence. Advised to continue HBT and Long term outcome was evaluated 1 year post therapy. Conclusion: Optometric Binocular Vision Therapy plays important role and highly effective in patients with intermittent exotropia of the basic type. Most importantly its eliminated the patients' symptoms of asthenopia and diplopia without the need for surgery.
