Normal visual activities have no effect on exotropia. In any case, when the eye is closed, the child cannot use both eyes together. [ 1] Occlusion: Patching the dominant eye or alternate patching of either eye is suggested to interrupt the process of suppression and to reduce the progression of the exotropia. Ing MR, Nishimura J, Okino L: Outcome study of bilateral lateral rectus recession for intermittent exotropia in children. Though the natural history remains to be fully elucidated, a few observational studies have addressed this. Intermittent exotropia is not typically associated with neurologic disease. However, it is still obscure whether intermittent exotropia and exophoria children could wear orthokeratology without experiencing aggravated lens decentration.

Intermittent exotropia is the most common form of strabismus, characterized by an intermittent outward deviation of the eyes, affecting as much as 1% of the population.1,2 This condition most often presents in childhood and affects females more than males. The treatment group showed significant enhancement of binocular function, particularly control of strabismus and stereoacuity for distance. This treatment does not make the eye misalignment go away; it only hopes to help it become less frequent. 1896,5:969; 18976:84,247. 1950 Mosby-Year Book, Inc. Lee SA, Sunwoo IN, Kim KW.

Mohney BG, Holmes JM. Govindan M,Mohney BG,Diehl NN,Burke JP. Introduction There is a high prevalence of intermittent exotropia and exophoria in myopic populations, and orthokeratology is one of the effective interventions to control myopia progression in children. Strabismus, or hypertropia, is a condition when one or both of the eyes are not properly aligned. Ophthalmol. Freeman RS, Isenberg SJ: The use of part time occlusion for early onset unilateral exotropia. Economides JR, Adams DL, Horton JC. However, it is still obscure whether intermittent exotropia and exophoria children could wear orthokeratology without experiencing aggravated lens decentration. In childhood strabismus, exotropia is most frequently seen with intermittent exotropia and convergence failure in the first decade of life. Abroms AD, Mohney BG, Rush DP, Parks MM, Tong PY. Esotropia is when an eye faces inward, and exotropia is when an eye faces outward. In a small child, part-time patching of the preferred eye is useful if the child prefers one eye over the other (). 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. Ann. Burian HM, Spivey BE. Sometimes the exotropia is noticed more when the patient is looking in the distance. Our hostel atmosphere is friendly and inviting. +3.0 D near add test (lens gradient method) - This test can distinguish pseudo-divergence excess from a high AC/A ratio rather than true divergence excess. 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. Noorden GK von. Results: The treatment group showed Some patients or family members notice the exotropia more when the patient is tired or daydreaming. Periocular Lymphangiomas: "Bleo-ing" in the Wind! Nusz KJ, Mohney BG, Diehl NN. Control of the intermittent deviation can vary throughout the day.3,4, The etiology of intermittent exotropia is largely unknown,5 and the deviating movement shares features with normal divergent eye movements, but divergence tone may exceed convergence tone in these patients, correlating with hypometric adduction saccades.6,7, Patients with intermittent exotropia are often asymptomatic, although children with the condition will occasionally close either eye, a symptom that may be exacerbated by bright light, giving the condition its alternate moniker, squint. Patients can also rarely report intermittent binocular horizontal diplopia or a sense of discomfort associated with eye deviation. Strabismus, or hypertropia, is a condition when one or both of the eyes are not properly aligned. If the visual problem is treatable, it should be addressed as soon as possible. Types Infantile esotropia This is an esodeviation, often constant, that presents in the first 12 months of life. We also offer discounts and other great promotions from time to time. Surgery is appropriate when exotropia is present for most of the patients waking hours, regardless of age. The content of this article is not intended to be a substitute for professional medical advice, examination, diagnosis, or treatment. St. Louis. [17], The deviation may become manifest during illness, fatigue or daydreaming. Kim C, Hwang JM. Families are usually concordant for either esotropia or exotropia, but families with both forms have been reported. Intermittent exotropia has been divided into four groups according to the classification system proposed by Burian. Poor Control: Patient who breaks spontaneously without any form of fusion disruption, or who does not spontaneously regain alignment despite blink or refixation. 1 The treatment of intermittent exotropia includes watchful observation, 2,3 patching, 2,3 prism, 4,5 overminus lens, 6 vision therapy 713 and surgery. Metchell P. Concomitant exodeviation. Surgical experiences with two-muscle surgery for the treatment of intermittent exotropia. The lack of randomized controlled This site needs JavaScript to work properly. It is the opposite of crossed eyes, oresotropia. An optometrist is an eye doctor who can examine eyes and prescribe eyeglasses or contact lenses. Grading the severity of intermittent distance exotropia: the revised Newcastle Control Score. Intermittent exotropia (X(T)) is one of the most common type of strabismus in children as well as adults, especially in the Asian and South Asian populations.14 In these populations, it has been estimated that the prevalence of exotropia can be up to 718.5 times higher than that of esotropia, out of which the most common type is X(T) accounting for Kushner BJ, Morton GV. In addition, the natural history of intermittent XT has not been rigorously studied and, anecdotally, some cases resolve without surgery. Scores from home, distance, and near measurements are added to calculate the final score.15,16, Realignment with aid of blink or re-fixation, Remains manifest after dissociation/prolonged fixation. Powered by Higher Logic. It can be found in every age group [See figures 1 and 2]. Part-time patching and pencil push-ups can improve intermittent exotropia control in pediatric patients. Children with intermittent exotropia commonly close or squint one eye at times, especially when they are exposed to bright sunlight. 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. Pratt Johnson JA, Barlow JM & Tilson G. Early surgery for Intermittent exotropia. Buck D, Clarke MP, Haggerty H, et al. Your pediatric ophthalmologist has ways to test this in the office. A randomized trial comparing bilateral lateral rectus recession versus unilateral recess and resect for basic-type intermittent exotropia. HHS Vulnerability Disclosure, Help Myopes, in particular, will often improve control of their intermittent exotropia if given corrective lenses. More and more visitors and international students prefer to stay at hostels than hotels. This page has been accessed 255,116 times. 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. [18] Von Noorden found that 75% of 51 untreated patients showed progression over an average follow up period of 3.5 years while 9% did not change, and 16% improved.[19]. Arch Ophthalmol. Before 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. Am Ortho J 1988;38:81-93. 2006 Feb;42(2):139-44. The distance angle to target in surgery for intermittent exotropia. Am J Ophthalmol. Intermittent exotropia is the most common type of strabismus. [3] [4][5] Other theories include innervational imbalance in the divergence centers in the areas of the tegmentum of the brainstem in humans and divergence burst cells in the area of the mesencephalic reticular formation [6]or abnormal position of the extraocular muscle pulley position. This topic will focus specifically on intermittent exotropia, which is the most common type of manifest exodeviation. According to Donders, this constant under-stimulation of convergence may cause an exodeviation to develop. Fusion exercises have been used in the management of intermittent exotropia (X(T)) for over one hundred years. Clipboard, Search History, and several other advanced features are temporarily unavailable. If your optometrist specializes in eye issues, you could have them examine your eyes for exotropia. Olitsky SE, Sudesh S, Graziano A, Hamblen J, Brooks SE, Shaha SH. Children with intermittent exotropia commonly close or squint one eye at times, especially when they are exposed to bright sunlight. However, affected family members do not necessarily share the same type and/or severity of strabismus. 1971. If the angle of the exotropia is small, prisms may be used to relieve double vision, particularly in adults, however it does not treat the eye misalignment itself. WebSometimes, intermittent exotropia stays mild or goes away on its own. Staying as healthy as possible may also help. 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.

For inferior oblique overaction with a significant V-pattern, the inferior oblique muscles may be weakened at the time of horizontal surgery. Patients and method: Caltrider N, Jampolsky A. Overcorrecting minus lens therapy for treatment of intermittent exotropia. Patch Test - The patch test is used to control the tonic fusional convergence to differentiate pseudo-divergence excess from true divergence excess and to reduce the angle variability. 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). In: Manley D ed. Divergence excess: distance deviation is 10 prism diopters greater than the near deviation. J Pediatr Ophthalmol Strabismus 1989;26:94-96. Current concepts in the management of concomitant exodeviations. Both alternate part-time patching and pencil push-up training In: symposium on horizontal ocular deviation. Youll also have access to a fully-equipped kitchen where you can prepare meals for yourself. It can be seen more commonly in children with hypotonia or developmental delay, but no specific workup is recommended when the sensorimotor examination is consistent with intermittent exotropia. 36 Children were randomized to "I have noticed some changes in my daughter's eyes, one in particular. Zhonghua Yan Ke Za Zhi. 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.
