Intermittent exotropia is the most common type of strabismus. However, other treatments include: Eye patching: The stronger eye is covered so the weaker eye gets Postoperative outcomes in children with intermittent exotropia from a population-based cohort. Transient intermittent exotropia is sometimes seen in the first 4 - 6 weeks of life and, if mild, can resolve spontaneously by 6 - 8 weeks of age. Families are usually concordant for either esotropia or exotropia, but families with both forms have been reported. This ensures that visitors can easily communicate with our staff to get their needs met. However, some people may be able to adequately control the drifting with glasses or other non-surgical means. You may have to physically train your eyes to move in coordination with games and other tools. Increased frequency of the manifest phase, Difficulty regaining fusion after dissociation during cover testing, Jampolsky A, Flom BC, Weymouth FS, Moster LE. At home: The parents may be told to keep a chart noting the control of deviation at home in terms of the percentage of waking hours the manifest deviation is noted at home. Bethesda, MD 20894, Web Policies Although this traditional Burian classification has been widely cited, Kushner has proposed a reclassification or expansion to include categories such as tenacious proximal fusion, high AC/A ratio, low AC/A ratio, proximal convergence, and pseudo-convergence insufficiency.13, There have been multiple methods described to quantify control of patients with intermittent exotropia. The parent and child sit on the floor with their legs in a V, about five to six feet apart. The lack of randomized controlled Otolaryngol. WebPrism lenses ease symptoms, but they dont fully fix exophoria. Exotropia occurs when there's an imbalance in eye muscles or when there's a signaling issue between the brain and eye.Sometimes a health condition, like cataracts or stroke, can cause this to occur.

Divergence excess: distance deviation is 10 prism diopters greater than the near deviation. A systematic review of the effectiveness of treatments in altering the natural history of intermittent exotropia. In: Duane TD ed. Accessibility Intermittent exotropia is not typically associated with neurologic disease. If no exotropia is observed during this period, scores of 2 and below are based on the worst of 3 10-second observation periods with occlusion.4,14, Constant exotropia during 30-second observation before dissociation, Exotropia >50% of the time during 30-second observation before dissociation, Exotropia <50% of the time during 30-second observation before dissociation, No exotropia noted unless dissociated, recovers in > 5 seconds, No exotropia noted unless dissociated, recovers in 1-5 seconds, No exotropia noted unless dissociated, recovers in < 1 seconds (exophoria), The Newcastle score and the updated Newcastle score incorporate data from both the clinic visit and from symptoms experienced at home and are scored from 0 to 9, with 9 being the worst control. Grading the severity of intermittent distance exotropia: the revised Newcastle Control Score. WebIntermittent exotropia usually starts to be seen after the age of 2 to 3 years but can be seen at any age. An UpToDate review on "Causes of horizontal strabismus in children" (Coats and Paysse, 2021) include treatment of intermittent exotropia. A prolonged alternate cover testing should be used to suspend tonic fusional convergence. Patient with Childhood exotropia may present with:-. The natural history of the disease is not fully understood. [7][8][9], An older theory suggests that the essential cause of exotropia is a defect of the fusion faculty and indeed is a congenital total absence of the fusion faculty. Did You Know? The opinions regarding their efficacy are controversial. A randomized trial comparing part-time patching with observation for children 3 to 10 years of age with intermittent exotropia. J Pediatr Ophthalmol Strabismus 1996:33:208. If significant superior oblique overaction and an A-pattern is present, one may consider a superior oblique weakening procedure at the time or horizontal muscle surgery.

Sensory exotropia may occur at any age. Strabismus, or hypertropia, is a condition when one or both of the eyes are not properly aligned. This entity is also named distance exotropia, divergent squint, periodic exotropia, or exotropia of inattention. In childhood strabismus, exotropia is most frequently seen with intermittent exotropia and convergence failure in the first decade of life. Ann.

Success rates have been described as 46% experiencing improved quality of fusion and 26% demonstrating improved quality of fusion and quantitative decrease in the angle of deviation.39 There are concerns that over-minus therapy could lead to increasing myopia, and while a retrospective study found that this therapy is not associated with increasing myopia in intermittent exotropia,40 results of a prospective Pediatric Eye Disease Investigator Group (PEDIG) study evaluating the efficacy of this treatment is forthcoming. This ocular misalignment has two main types: esotropia and exotropia. Bookshelf In: Binocular Vision and Ocular Motility 5 th ed., 1996 Mosby.

Transient intermittent exotropia is sometimes seen in the first 4 - 6 weeks of life and, if mild, can resolve spontaneously by 6 - 8 weeks of age. Intermittent exotropia (IXT) is the most common type of strabismus in China, but the best treatment and optimal timing of intervention for IXT remain controversial, particularly for children with moderate IXT who manifest obvious exodeviation frequently but with only partial impairment of binocular single vision. Periocular Lymphangiomas: "Bleo-ing" in the Wind! See your ophthalmologist as often as recommended, to keep the vision up to date if glasses are needed. Eye exercises work best for smaller amounts of eye drifting. 1983;90:1172-1177. Medial Rectus Resection: Bilateral medial rectus resections are thought to be useful for the treatment of the convergence insufficiency type of intermittent exotropia because of the increased effect of this surgery at near. government site.

Webstrabismic children may prevent amblyopia.1 The strabismic child with amblyopia has a significantly higher risk of becoming blind by losing vision in the non-amblyopic eye, due to trauma or disease. Some have proposed the use of alternate day, alternate eye patching, but this generally works best in young children to regain control. 2005 Jan;112(1):104-8. Intermittent exotropia is a very common type of eye misalignment. One or both eyes turn out toward the ear occasionally. Only one eye turns out at a time while the other eye points straight forward. The cause of this condition is not known. Most experts believe that the brain of affected patients has trouble controlling the position of the eye.

For example, getting the recommended amount of sleep for age is importantmany children dont! You can do this exercise as often as you like throughout the day. Management options include the following: In intermittent exotropia, one of the important indications for surgery is an increasing tropia phase, since this indicates deteriorating fusional control. Generally, near stereoacuity is normal in patients with intermittent exotropia, although distance stereopsis can often be worse than normal controls.17 Decreased distance stereoacuity likely represents poor control of the deviation, and is often considered in determining who should undergo surgical correction (see below).
