The Esotropia and Exotropia Preferred Practice Pattern was then sent for review to additional internal and external groups and individuals in June 2012. Active vision therapy done under the supervision of an eye care provider has been shown to produce better results than simple convergence activities at home (called pencil push-ups). Sit in front of your computer with your back straight and eyes level with the computer screen. Mechanical exotropia is often due to fibrosis (or scar tissue) that prevents the eye from moving inward. Vision therapy for exophoria has a similar appearance for esophoria, but the key focus is working on convergence. Vision Therapy Success Stories. Control of the intermittent deviation can vary throughout the day. Note: Esotropia is a convergent misalignment of the visual axes; exotropia is a divergent misalignment of the visual axes. The world's most advanced vision care platform. The potential benefits of treatment for exotropia include promoting binocular vision and normal visual function in each eye. This would be called a unilateral (right or left) exotropia. An implementation strategy was not provided. Insufficient quality - Further research is very likely to have an important impact on confidence in the estimate of effect and is likely to change the estimate; any estimate of effect is very uncertain. Disadvantages of botulinum toxin A injection include the frequent need for repeat injection(s), especially with larger preoperative angles; iatrogenic ptosis, which may increase the risk for amblyopia; and the need for general anesthesia. This position may be: To better define the movement, the ending -phoria or -tropia is added. Exotropia is also often called wall-eyed. After strabismus surgery, adults have reported improved confidence, self-esteem, and interpersonal interactions.

COVD doctors will thoroughly evaluate this condition and provide treatment options. Ratings of the strength of the recommendations (Strong, Discretionary) and quality of evidence (Good, Moderate, Insufficient) are defined at the end of the "Major Recommendations" field. Asthenopia (eye fatigue) can also occur with reading. Complete details of the literature search are available from the American Academy of Ophthalmology Web site. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria.People with exotropia often experience crossed diplopia.Intermittent exotropia is a fairly common condition. The symptoms are quite similar: Anything that forces the eyes to converge can make the symptoms of exophoria worse, so these symptoms are often noticed when reading or other near work. During a vision exam and eye specialist may repeat eye position testing at different distances, in different positions of gaze, or with different targets to see if the patient's phoria breaks down and becomes an intermittent tropia. The distinguishing sign of exotropia is one or either eye wandering outward. The Academy has Relationship with Industry Procedures to comply with the Code (available at http://one.aao.org/CE/PracticeGuidelines/PPP.aspx). Press-On prisms cause visual symptoms that some children find objectionable (blurred vision with poor compliance with eyeglasses). Guidelines for Refractive Correction in Infants and Young Children. Fusion and stereopsis are necessary for some careers and may be useful in others as well, such as in athletic activities and activities of daily life. Eye positioning is tested using acover test. Add a note. Patching one eye may make the patient more aware of the eye that is misused, leading to gradual correction of the eye turn. © All Rights Reserved, Vivid Vision, Inc. A common form of exotropia is known as " convergence insufficiency " that responds well to orthoptic vision therapy including exercises. Literature searches to update the Preferred Practice Pattern were undertaken in April 2011 in PubMed and the Cochrane Library and updated in March and September of 2012. If eye teaming and coordination is lost, the eyes move outward and out of alignment and a person sees double. Treatment for exotropia aims to ensure proper vision in both eyes and to straighten the eyes. Binocular vision makes it easier for us to ride a bicycle, drive a car, or direct many other daily activities. RE: Vision Therapy or Surgery for Exotropia by Mrs. Hyden Below is a thank-you letter sent to an eye doctor who provides Optometric Visual Therapy or Visual Training. If you're experiencing any of these symptoms, it may be time for an eye examination. This is done through a series of guided tasks or exercises that work on critical skills such as recognition of poor eye coordination, improving convergence ability, improving divergence ability, and improving the ability to rapidly change between convergence and divergence. So exoTROPIA is a visible outward deviation of one or both eyes and exoPHORIA is only visible when testing eye position and breaking fusion. Some conditions, such as overactive thyroid, can leave deposits in muscles and cause an abnormal tightness for an eye muscle to move. A clinician covers one eye at a time, and then alternates between the eyes to disrupt fusion and watch how the eyes react. Improving lives by advancing excellence in optometric vision therapy and rehabilitation through education and board certification. All those returning comments were required to provide disclosure of relevant relationships with industry to have their comments considered. Repeat cycloplegic refraction is indicated when esotropia does not respond to the initial prescription of hyperopic refraction or when the esotropia recurs after surgery. The updated information was verified by the guideline developer on April 2, 2003. Exotropia is the easiest type of strabismus to treat with vision therapy, saving the patient from the risks and uncertainties associated with strabismus surgery and the liklihood of repeat surgeries. Patients with an alternating fixation pattern switch fixation between each eye. Surgery is almost never required for exophoria, since non invasive treatment options are available. Special glasses with prisms can be used to decrease double vision in patients with constant exotropia. FDA Registration Number 3014400613 An eye that wanders is much more than just an appearance problem. (Strong recommendation, Moderate evidence), In patients with exotropia and a high accommodative convergence to accommodation ratio (AC/A), treatment with eyeglasses is generally preferred over surgery because of the risk of consecutive esotropia and diplopia after surgery. (Moderate evidence), Socioeconomic Considerations for Strabismus. Intermittent exotropia makes up about 50-90% of the cases of exotropia. For example, reading demands accurate binocular vision. ", Monday          11:00 am - 7:00 pm © All Rights Reserved, Vivid Vision, Inc. Patching may also work in some cases. If the deviation is visible even without breaking fusion, the ending is -tropia.
