Cause of intermittent exotropia The cause of this condition is not known. Exotropia in Children and Adults - EyeHealthWeb.com Buck D, Clarke MP, Haggerty H, et al. 2005 Jan;112(1):104-8. Institutional Review Board approval was obtained from the Institutional Review Board at Mayo Clinic, Rochester, MN, USA and all procedures and data collection were conducted in a manner compliant with the Health Insurance Portability and Accountability Act. In: Strabismic Ophthalmic Symposium I, St. Louis, Ed Allen JH. Some have proposed the use of alternate day, alternate eye patching, but this generally works best in young children to regain control. Female predominance in intermittent exotropia. Richard JM, Parks MM: Intermittent exotropia: Surgical results in different age groups. The angle of the exodeviation measures the same at distance and at near. When shes not working, Dr. Huang loves reviewing new skin care products, trying interesting food recipes, or hanging with her adopted cats. In: symposium on horizontal ocular deviation. A randomized trial comparing part-time patching with observation for children 3 to 10 years of age with intermittent exotropia. 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. Hatt SR, Leske DA, Yamada T, Bradley EA, Cole SR, Holmes JM. Pineles SL, Ela-Dalman N, Zvansky AG, Yu F, Rosenbaum AL. In the context of this uncertainty, it is not unreasonable to ask whether childhood intermittent XT can be cured'. These children are usually between the ages of 2 and 4 years. The 2 classic surgical procedures for intermittent exotropia are bilateral lateral rectus muscle recessions, or a unilateral medial rectus muscle resection combined with a lateral rectus muscle recession. Kushner BJ: Exotropic deviations: A functional classification and approach to treatment. 1983;90:1172-1177. The condition impacts as much as 1 percent of the U.S. population.8 It is more common in females than in males. The natural history of surgically untreated intermittent exotropia-looking into the distant future. St. Louis. The tropia is usually larger at distance than near. Holmes JM, Leske DA, Hatt SR, Brodsky MC, Mohney BG. 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. While it is possible for exotropia to become less frequent with age, most forms of exotropia do not resolve completely. However, most forms of the condition do not resolve completely . We compared long-term cure rates in children with surgically and non-surgically managed intermittent XT. There you can speak with a professional eye care specialist. Intermittent Exotropia. Joyce KE, Beyer F, Thomson RG, Clarke MP. Exotropia is a eye turn where one eye points outwards, this may be noticed while the child is looking at distance objects, near objects or both.. There are several theories as to why intermittent exotropia develops. There is a higher success rate in the long run for those with intermittent exotropia and with stronger binocular function at the time of surgery. Currently, he has spent the past 5 years working as a freelance health content writer and medical editor for different public hospitals in central Barcelona. None of the sponsors or funding organizations had a role in the design or conduct of this research. This page was last edited on March 30, 2023, at 12:41. If a patient is nearsighted or has highastigmatism, keeping the glasses prescription up to date may help control the alignment. : International strabismus symposium, Basel 1968, S. Karger AG 319. Exotropia is a form ofstrabismus(eye misalignment) in which one or both of the eyes turn outward. For each surgical patient, we selected the first non-surgical patient from the ordered list with the same age at onset and with a follow-up examination at the same age (within 1 year) of the surgical patient's 5-year postoperative examination. 1 Nevertheless, there is no consensus regarding the optimum type of treatment and the optimum timing of treatment. Divergence excess: distance deviation is 10 prism diopters greater than the near deviation. [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. 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. Near stereoacuity: In a study it was shown that near stereoacuity does not correlate well with the degree of control in intermittent exotropia. More recently, Kim et al22 defined success as alignment within 10 PD and reported a 62% success rate at 2 years postoperatively. In other studies, a successful outcome or cure has been defined using more comprehensive criteria than purely angle of deviation. The Development of Myopia Among Children With Intermittent Exotropia., Strabismus (Crossed Eyes): Types, Causes, Symptoms & Treatment., Outward turning of the eyes. The occurrence of monofixational exotropia after exotropia surgery. The acquired forms of exotropia include intermittent exotropia, sensory exotropia, and consecutive exotropia (exotropia that develops after surgery to treat crossed eyes). 1950 Mosby-Year Book, Inc. Lee SA, Sunwoo IN, Kim KW. In this retrospective study evaluating long-term outcomes in children with intermittent XT, surprisingly, we found a low cure rate with surgery, which was somewhat similar to the cure rate in conservatively managed patients (30 vs 12% P=0.1, difference 18%, 95% CI 1 to 37%). Dadeya S, Kamlesh Long-term results of unilateral lateral rectus recession in intermittent exotropia. Previous authors have suggested that evidence of monofixation postoperatively is attributable to monofixation being present preoperatively.17, 26 Nevertheless, it appears that monofixation can be induced through surgical intervention, as highlighted in the study by Pratt-Johnson et al.23 Although it has been proposed that a postoperative microtropia with monofixation is a good result that lends itself to long-term motor stability,27 our data suggest few if any of these patients did in fact have good long-term alignment. Dunlap EA. Motor success was defined as no observed manifest deviation by clinic examination and by history. Exotropia can become less frequent as you age. Demer JL, Miller JM, Poukens V, et al. Freeman RS, Isenberg SJ. Exotropia - All About Vision There is no specific, known cause of exotropia. A prolonged alternate cover testing should be used to suspend tonic fusional convergence. Anthony Armenta earned his B.A. It will also turn outward. Clark RA, Demer JL, Rosenbaum AL. The Newcastle Control Score: a new method of grading the severity of intermittent distance exotropia. Strabismus (Misaligned Eyes): Symptoms, Causes & Treatment Economides JR, Adams DL, Horton JC. Exotropia - Eyes 4 Kids sharing sensitive information, make sure youre on a federal However, in older children, the eye often becomes exotropic. Those with exotropia may experience some symptoms of exotropia or show signs. Exotropia may occur rarely and result in few or no symptoms. For example, cerebral palsy or Down syndrome, Refraction to test for uncorrected refractive error. Long-term outcomes of unilateral lateral rectus recession versus recess-resect for intermittent exotropia of 20-25 prism diopters. Powered by Higher Logic. Other times, the eyes are straight. Accessibility All research procedures adhered to the tenets of the Declaration of Helsinki. With intermittent exotropia, one eye turns outward on occasions. Maternal smoking during pregnancy and low birth weight are significant and independent risk factors for the development of horizontal deviations. Kim C, Hwang JM. Hatt SR, Gnanaraj L. Interventions for intermittent exotropia. In a small child, part-time patching of the preferred eye is useful if the child prefers one eye over the other (). Ophthalmol. The latter condition may link with an underlying medical condition. Exotropia is a form of strabismus . 3,4 Etiology Small children who won't wear sunglasses may be offered a hat with a brim, such as a baseball cap, to shield the eyes from the sun, thereby limiting the need to squint. Exotropia (Outward Turning Eyes): Types, Causes & Treatment 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. INTERMITTENT EXOTROPIA: A Major Review - University of Iowa Strabismus. in the United Kingdom, 1 supports Dr. Rosenbaum's premise that intermittent exotropia is not fully understood. Patients with IXT can control the deviation and keep the e Large angle exotropia of more than 50 prism diopters may require bilateral lateral rectus recessions combined with resection of one or more medial rectus muscles, even in the presence of amblyopia. Am J Ophthalmol. A doctor of optometry should examine any child older than 4 months whose eyes do not appear to be straight all the time. This study was previously presented in part at the Cambridge Ophthalmological Symposium, Cambridge, England, 5 September 2014. Ten (30%) of 33 patients in the surgical cohort had no manifest deviation recorded by history or by examination and no intervening surgical intervention (Table 1). The cure rate at 5 years was 30% in the surgical group and 12% in the non-surgical group (P=0.1; difference 18%, 95% CI 1 to 37%). Ekdawi NS, Nusz KJ, Diehl NN, Mohney BG. Children with intermittent exotropia commonly close or squint one eye at times, especially when they are exposed to bright sunlight. London 1929, Bailliere, Tyndall and Cox. For conservatively managed patients, we found the rate of monofixation ranged from 13% (interim examination) to 21% (5-year follow-up), which is similar to the prevalence of monofixation in unselected children presenting with intermittent XT reported in previous studies.16, 17 Although we have previously reported the risk of misclassifying monofixation due to test-retest variability,16 we would expect any misclassification to be similar between non-surgical and surgical groups. A randomized trial comparing part-time patching with observation for children 3 to 10 years of age with intermittent exotropia. Received 2014 Sep 26; Accepted 2014 Oct 10. . Infantile esotropia: In this type of strabismus, infants show a significant inward turning of both eyes before they're 6 months old. INTERMITTENT EXOTROPIA: A Major Review Contributor: Rahul Bhola, MD The University of Iowa January 19, 2006 Introduction Exodeviations or divergent squint occurs as a result of certain obstacles to development or maintenance of binocular vision and/ or due to defective action It can be found in every age group [See figures 1 and 2]. However, it is more typical to find exotropia developed while a child is 1 to 4 years old. One or both eyes turn out toward the ear occasionally. A nonrandomized, case-controlled study of children aged 3 to 144 months with intermittent exotropia showed similar results to those in prior surgical reports when they received injections of 2.5 units of Botox into each of the lateral rectus muscles.34 In this study, 69% of patients injected with Botox were orthophoric 12 to 44 months following the intervention. J Pediatr Ophthalmol Strabismus 1996:33:208. Exotropia may occur from time to time (intermittent exotropia) or may be constant. the contents by NLM or the National Institutes of Health. Intermittent exotropia is a condition in which there are times when one eye has drifted outwards, and other times when the eyes are straight. Copyright 2023 VisionCenter.org. It may affect about 1% of the population. Through her writing, Dr. Huang enjoys educating patients on how to lead healthier and happier lives. 1Department of Ophthalmology, Mayo Clinic, Rochester, MN, USA. Initially, if an infant or young child has a blind or poorly seeing eye, esotropia develops. Around 1% of the population is thought to have some degree of intermittent exotropia. Some people may describe that their vision becomes blurry or they may experience double vision when their eyes are misaligned. 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.1-4 In these populations, it has been estimated that the prevalence of exotropia can be up to 7-18.5 times higher than that of esotropia, out of which the most common type is X(T) accounting for about 63%.1 2 5 It is . Control of the intermittent deviation can vary throughout the day. Abroms AD, Mohney BG, Rush DP, Parks MM, Tong PY. It is the opposite of crossed eyes, or esotropia. The intermittent deviation is more likely to be manifest when fatigued, ill, or in a lowered mental state (ex. In addition, we found that the surgical patients on average showed a larger angle of deviation and worse control preoperatively compared with non-surgical patients, which may indicate more severe or more progressive disease in the surgical patients, making the groups less comparable. Sometimes the exotropia is noticed more when the patient is looking in the distance. Govindan M, Mohney BG, Diehl NN, Burke JP. and transmitted securely. One hundred and thirty-four children with intermittent XT and at least 5 years of total follow-up were identified. Chia A, Seenyen L, Long QB. Basic Clinical Sciences Course, Pediatric Ophthalmology and Strabismus. Normal visual activities have no effect on exotropia. Medically Reviewed by Dr. Melody Huang, O.D. Here is a list of some eye diseases that could increase the likelihood of developing exotropia: Additionally, these risk factors may increase the probability of exotropia: It is essential to understand that exotropia is not a disease in and of itself. Intermittent Exotropia - American Academy of Ophthalmology Intermittent Exotropia, X (T) for short, describes an intermittent divergent misalignment of the visual axes which is initially observed when fixation is at distance rather than near, and during periods of fatigue and inattention. Br Orthopt J. Interestingly, for the total surgical cohort of 33 patients, 7 patients had a second surgery prior to the 5-year examination, 4 for consecutive esotropia, 2 for recurrent exotropia, and 1 treated with botox for consecutive esotropia. The distance angle to target in surgery for intermittent exotropia. Classification of the exodeviations. Hatt SR, Mohney BG, Leske DA, Holmes JM. The prevalence of monofixation at the 5-year follow-up examination was significantly higher in the surgical cohort compared with the non-surgical cohort (55 vs 21% P=0.01, Table 1). Am J Ophthalmol. Manley DR. It's not the same as esotropia. Intermittent exotropia is an eye condition that develops in the first year of life. Heterotropic rectus extraocular muscle pulleys simulate oblique muscle dysfunction. Etiology Intermittent Exotropia - EyeWiki Exodeviations (from Greek , "exo" meaning "to exit" or "move out of") are either manifest (exotropia) or latent (exophoria). Philadelphia 1899. Common sense approaches may help to control intermittent exotropia. Manley DR. 1971 Mosby-Year Book, Inc., pg 119. Exotropia may be congenital (present at birth) or acquired. Non-surgical treatment may include glasses and, in some instances, patching therapy may be recommended. Prescribing 2.0 to 4.0 diopters of myopic correction to the refraction of children with intermittent exotropia is thought to induce convergence, promote fusion, and decrease the angle of the eye misalignment. Hypertropia: upward turning. This type of exotropia is rare and will cause no to few symptoms. 1896,5:969; 18976:84,247. The BJO study, conducted by Buck et al. Often, your eye will alternate between looking straight and turning outward. Our data suggest that surgical intervention in intermittent XT is far from a panacea and that conservative management, including watchful waiting, can sometimes result in an excellent outcome. Goal-determined metrics to assess outcomes of exotropia surgery. Watts P, Tippings E, Al-Madfai H. Intermittent exotropia, overcorrecting minus lenses, and the Newcastle scoring system. It affects about 1% of the general population.[1][2]. For these 10 patients, the angle of exodeviation was <10 PD at distance and near for all but one patient, who interestingly was prescribed over-minus lenses at the 5-year postoperative examination for an exodeviation of 8 PD at distance and 12 PD at near. Scores of 5 to 3 are based on a 30-second observation period. Please contactinfo@aapos.orgif you would like to request a refund.
