Onset is before age 6 months and persists beyond this age (Figure 1).1,2,3 It is classified as primary infantile exotropia, where patients are healthy with no evidence of systemic or ocular disease (Table 1).2 It usually occurs sporadically,1,4 but may be familial as autosomal dominant inheritance with variable penetrance, as was suggested in one case report.5 Some authors classify early onset intermittent exotropia in this subclassification.2 A list of causes for secondary infantile exotropia can be found in Table 1. Clinical features and the risk factors of infantile exotropia recurrence. Your baby may also have: Always check with your doctor if your baby or toddler has any kind of eye infection or changes to the eye or eyelid. Potential cases of intermittent exotropia were identified using the resources of the Rochester Epidemiology Project, a medical record linkage system designed to capture data on any patientphysician encounter in Olmsted County, Minnesota.9 The racial distribution of Olmsted County residents in 1990 was 95.7% Caucasian, 3.0% Asian American, 0.7% African American, and 0.3% each for Native American and other. Whether or not a patient underwent surgical correction did not appear to have an impact on his or her rate of myopic progression. It usually appears for a short time while youre doing certain types of tasks. It usually begins as exophoria. Eye muscle surgery is usually a better option when there is a large amount of eye drifting, Patching one or both eyes The value of eye patching for the purpose of improving eye alignment is unclear.

However, the mean age at the final refraction for the 135 study patients was 18 years, an age at which a cycloplegic refraction is uncommonly performed for patients with myopia. Patients with positive angle kappa, although showing a nasally displaced Hirschbergs corneal light reflex, will have no refixation movements on alternate prism cover tests, and will have good sensory fusion. Hypertropia happens when either eye drifts or looks upward. Its best to be safe. [QxMD MEDLINE Link]. Michael J Bartiss, OD, MD Medical Director, Ophthalmology, Family Eye Care of the Carolinas and Surgery Center of Pinehurst Exotropia in Children - Wicha Lab J Pediatr Ophthalmol Strabismus. The angle of deviation was primarily determined by the prism and alternate cover technique at both distance and near, although some younger patients were measured by the Hirschberg or modified Krimsky techniques at near.

The main sign of exotropia is an eye that is not straight. Patients not residing in Olmsted County at the time of their diagnosis were excluded. When intermittent exotropia develops in a child whose visual system is still immature, bitemporal suppression develops, and the child does not perceive 2 separate images (diplopia). Optimal surgical timing in infantile exotropia. In adults, the tendency is toward exotropia. Mosby Year Book. Nam KT, Kim SH. The most common cause of hypertropia is palsy (weakness) in one of the cranial nerves, the third or fourth nerve. Consecutive exotropia can occur immediately after the intervention or appear years after having undergone it. Since no patient had greater than 1 diopter of anisometropia, the refractive errors of the right and left eyes were averaged. Infants' eyes usually align by the age of 2 to 3 months, even if the eyes seem to wander in newborns. Some patients have panoramic view i.e. How is strabismus diagnosed? Draw three barrels of progressive size in red lengthwise on one side of a card. Alternate occlusion of eyes may be done in cases showing equal preference. Donate to help find cures, fuel innovation and provide world-class care for every child.

Exotropia Running together of words or missing of the word being read, due to divergence of eyes. Crossed eyes are common in children. Patient with intermittent exotropia at distance only. Constant exotropia may be of following types:-, According to distance-near relationships, exodeviations may be further subdivided as (Duane classification):-. There were 106 patients with 2 or more refractions separated by at least 1 year through 21 years of age, of which 43 underwent surgery and 63 were observed. Choi YM, Kim SH. Auzemery A, Andriamanamihaja R, Boisier P. [A survey of the prevalence and causes of eye disorders in primary school children in Antananarivo].

What Is In: Binocular Vision and Ocular Motility, Theory and Management of Strabismus, 356-376. 1983 Oct. 90(10):1160-5. A study by Archer et al identified that only 2 in 3000 (6 per hundred thousand) neonates develop true primary infantile exotropia,6 although other researchers estimated this at 1 in 30,000 births in the general population.4 Older literature suggested that infantile exotropia may be more common in patients of Asian and African descent.3, Theories as to neurophysiologic causes of infantile exotropia include (1) deficient development of the convergence system during the vulnerable early period between 2 and 4 months of age;6, 7 (2) monocular defocusing and total deprivation from birth;8, 9 (3) disruption of binocular vision shortly after birth, altering the development of normal vergence reflexes;6 (4) disruption of normal binocular processing in the visual cortex.10 Neuro-anatomic causes include (5) asymmetry in muscle structure between the lateral rectus and medial rectus;11 and finally (6) increased diameter of the lateral rectus compared to the medial rectus.12 However, in the latter two studies, whether the deviation caused the changes in the muscle or the muscle anatomy led to the deviation is unclear.2, Primary infantile exotropia in a patient is heralded by onset of outward deviation before 6 months of age, preferably with confirmation by an ophthalmologist by age 1 year.2 Alternatively, photographs that clearly show the patients age at the time a deviation is documented can aid in diagnosis. Exodeviation is a horizontal form of strabismus characterized by visual axes that form a divergent angle. Surgery for infantile exotropia should be performed within the first six months of life to maximize potential for attaining single binocular vision with stereopsis.4 Reasonable sensorimotor results are obtained in healthy infants aligned before age 2 years.1, 4, 21, 22 Experts agree that once diagnosis is made, after only a few weeks of follow-up to establish repeatable, reproducible angles of deviation and amblyopia treatment has commenced, surgery should be performed with minimal delay. Rose KA, Morgan IG, Smith W, Burlutsky G, Mitchell P, Saw SM. Occasionally, a deeply amblyopic convergent eye may become divergent (acquire resting position of eye). If you have exotropia, one or both of your eyes [QxMD MEDLINE Link]. Heredity appears to have role in exodeviation. Arch Ophthalmol.

WebExcess blinking is often present Treatment of intermittent exotropia Treatment recommendations depends on the severity of the problem, on the signs and symptoms, Philadelphia, WB Saunders, 1999. If there is family history of pediatric eye diseases, we recommend an early comprehensive eye examination. In the very young child who will not cooperate for alternate prism cover testing either at distance or near fixation, the Krimsky or modified Krimsky test at near may be all that is feasible to estimate the degree of the deviation. 13(2):71-3. Can it be maintained? This disorder is characterized by an inability of the eyes to work in unison when the child attempts to use the eyes at near only (e.g. Get another sterile pad and continue wiping and dabbing at the eyes.

Otherwise, practicing good hygiene especially if your baby is an eye-rubbing machine is the best preventive measure. Certain conditions, such as third nerve palsy, thyroid ophthalmopathy, and iatrogenic trauma following retinal detachment surgery or endoscopic sinus surgery, could cause acquired exotropia; however, these conditions are not discussed in this article. At the beginning of the disease, the symptoms are more evident when the child is looking towards the horizon. All refractions were converted into their spherical equivalent. Botulinum toxin injection in extraocular muscles may be used in patients with constant exotropia who are at risk of postoperative diplopia and also who have undergone multiple operations. Am J Orthop. In: Rosenbaum AL & Santiago A (eds):P Clinical Strabismus Management, Principles and Surgical Techniques, pp 176-201.

Sensory deprivation exotropia is due to disruption of binocular reflexes by acquired conditions like opaque media due to a disease or cataract. Institutional review board approval from the Mayo Clinic and the Olmstead Medical Group was obtained for this study. Surgery is required almost universally in cases of true infantile exotropia. Archer SM, Sondhi N, Helveston EM: Strabismus in infancy. A double win! Philadelphia, WB Saunders. Additionally, although the region is relatively isolated, some exotropic residents of Olmsted County may have sought care outside of the region, thereby potentially biasing the study population.

Infantile exotropia is a relatively rare strabismus disorder characterized by outward deviation of one or both eyes. [QxMD MEDLINE Link]. WebThis occurs most often when a child is focusing on distant objects. It might be harder to get your baby or toddler to stop touching or rubbing their eyes or touching their face. Basic exotropia: Exotropia is equal for both near and distance vision. In correct vision, these muscles work together receiving signals from the brain and directing the movements of the eyes so that they focus on the same object. Do the same thing in green on the other side. Development of binocular fixation in human infants. There were 44 (33%) male and 91 (67%) female patients. One hundred and six patients met these criteria with a mean follow-up of 8.2 years (range, 1.0 to 18.8 years). Children With Intermittent Exotropia Arch Ophthalmol. Exotropia is a form of strabismus, a misalignment of the eyes. A much more common result is undercorrection. Because of its rarity, there are few population-based studies to identify its true incidence. Patient is fixing with the left eye. In a recent paper, authors suggested that postoperative surgical outcomes appear to be influenced more by the duration of the misalignment, rather than the age at surgery.30 This would suggest that the timing of early surgery is of equal particular importance in the management of infantile exotropia and infantile esotropia. Early visual deprivation results in persistent strabismus and nystagmus in monkeys. Trans Ophthalmol Soc U K. 1973. The Kaplan-Meier rate of developing myopia in the surgery group versus the observation group is shown in Figure 3. Biglan A. This can also help open up a blocked tear duct. Finally, the demographics of Olmsted County limit our ability to extrapolate the findings from this study beyond other semi-urban white populations of the United States. Pink eye may cause slightly different symptoms in each child. As its name infers, intermittent exotropy is what causes eyes turned out occasionally, that is, there are periods in the life of the person in which he suffers from exoforia and others in which he does not. 28 and IXT. Chua WH, Balakrishnan V, Chan YH, et al. It may decrease the exotropia. If your baby has a bacterial infection, they may need antibiotics. Using the resources of the Rochester Epidemiology Project, the medical records of all children (<19 years) diagnosed with IXT as residents of Olmsted County, Minnesota, from January 1, 1975 through December 31, 1994 were retrospectively reviewed for any change in refractive error over time.

Other tests that may be considered in the cooperative child include saccadic velocity analysis, passive forced duction testing, and the active force generation test.16, Aside from a positive angle kappa that has an eye that appears to be deviated outward, the misalignment should be differentiated from early onset intermittent exotropia. Lambert SR. Are there more exotropes than esotropes in Hong Kong? Other theories and studies find different causes, such as: Exotropia usually manifests during childhood, between the 2 and 4 years old, and is quite noticeable when the child looks at an object at a long distance. It is less common in the United States and Europe. Yam JC, Chong GS, Wu PK, et al. Prognostic factors predicting the surgical outcome of bilateral lateral rectus recession surgery for patients with infantile exotropia. Active anti-suppression and diplopia awareness techniques may be used in cases of suppression. Hypertropia is a type of strabismus, also known as misalignment of the eyes. Hypertropia happens when either eye drifts or looks upward. Infants' eyes usually align by the age of 2 to 3 months, even if the eyes seem to wander in newborns.
