Types Infantile esotropia This is an esodeviation, often constant, that presents in the first 12 months of life. Parks MM. The distance angle to target in surgery for intermittent exotropia. Intermittent exotropia has been divided into four groups according to the classification system proposed by Burian. Another surgical technique that has been described is the augmented bilateral lateral rectus recession.28 This is an updated surgical table that proposes recessing an additional 1.5 2.5 mm per eye to Parks formula based on the angle of the deviation. Often, exposure to bright light or photography may elicit eye closure of the non-dominant eye. WebIntermittent exotropia is the most common form of exotropia and it is estimated that approximately 3% of Chinese teenagers suffer from this condition. Eye exercises work best for smaller amounts of eye drifting. wikiHow is where trusted research and expert knowledge come together. Orthoptics: Convergence exercises such as pencil push-us or computer orthoptics may be helpful in patients with convergence insufficiency who have a remote near point of convergence, or in whom poor fusional convergence amplitudes are demonstrated. Over time, the deviation can remain stable, resolve or progress, however patients maintain normal retinal correspondence and good binocular function when they are ortho. An office-based scale for assessing control in intermittent exotropia. 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. FOIA Patient may experience eyestrain following prolonged near work. Most studies have failed to show that age at time of surgery makes any difference in outcome. Lombardy is home to several hostels and other types of accommodation. Base-in prisms can be used to neutralize the deviation to stimulate fusion, or to overcorrect the deviation in the hope of reducing the deviation,38 but this treatment modality is not commonly used today. Fair Control: Patient blinks or refixates to control the deviation after disruption with cover testing. Vision therapy for intermittent exotropia: A case series. 1977;84:689. However, it is still obscure whether intermittent exotropia and exophoria children could wear orthokeratology without experiencing aggravated lens decentration. Unlike Bed & Breakfasts or hotels, our services are way more affordable. 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. The angle of the exodeviation measures greater at distance than near by 10 prism diopters. This situation adversely 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. This hotel is situated in Porta Romana with Bocconi University, Fondazione Prada and the University of Milan nearby. Incidence and types of childhood exotropia: a population-based study. Tip: If your child with exotropia doesn't like wearing a patch, get your child excited about the patch by letting them pick out a colorful patch with a fun pattern. Criteria for surgery may vary somewhat, but generally surgery is indicated when the exotropia is frequently present, when the patient is experiencing significant symptoms (eyestrain, double vision, squinting), or when there is evidence that the patient is losing "binocular vision." Myopes, in particular, will often improve control of their intermittent exotropia if given corrective lenses. Patients and method: The many enigmas of intermittent exotropia. Duane A. Unauthorized use of these marks is strictly prohibited. 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. Intermittent exotropia is not typically associated with neurologic disease. If you only find white patches, let your child decorate the patch with their choice of stickers. Your pediatric ophthalmologist will discuss the ideal timing of surgery for your situation. The long-term survival analysis of bilateral lateral rectus recession versus unilateral recession-resection for intermittent exotropia. Before 4 = Exotropia > 50% of the exam before dissociation, 3 = Exotropia < 50% of the exam before dissociation, 2 = No exotropia unless dissociated, recovers in > 5 seconds, 1 = No exotropia unless dissociated, recovers in 15 seconds, 0 = No exotropia unless dissociated, recovers in < 1 second (phoria).

Eye exercises Prisms (thick prismatic glasses to reduce how much the eye has to turn) A patch over the good eye or drops to make the strong eyes vision blurry (this forces the weaker eye to try to align and focus) Surgery on the eye muscles Vision correction is the first step in almost every strabismus treatment plan. Near stereoacuity: In a study it was shown that near stereoacuity does not correlate well with the degree of control in intermittent exotropia.

Hoyt CS, Pesic A. Background: To assess the clinical effectiveness of orthoptic therapy in the postoperative stabilisation and rehabilitation of binocular function in children with intermittent exotropia (IXT) after surgery. Presented at the 22nd annual meeting of the American Association for Pediatric Ophthalmology and Strabismus 1997. 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).

Children with intermittent exotropia commonly close or squint one eye at times, especially when they are exposed to bright sunlight. A family history of strabismus is an indication to be seen by a pediatric ophthalmologist. The exact reason people with intermittent exotropia close one eye in bright light remains unknown. Some have proposed the use of alternate day, alternate eye patching, but this generally works best in young children to regain control.

Due to lack of a standard definition for a successful outcome, variability in classification systems, multiple treatment approaches, and a paucity of long-term data it is difficult to determine the true outcome of currently available treatments for intermittent exotropia. In any case, when the eye is closed, the child cannot use both eyes together. [15][16], Intermittent exotropia typically begins before the age of 5 years old. This topic will focus specifically on intermittent exotropia, which is the most common type of manifest exodeviation. You should always contact your doctor or other qualified healthcare professional before starting, changing, or stopping any kind of health treatment.
