Causes of intermittent exotropia
Causes of intermittent exotropia-Exodeviation is a horizontal form of strabismus characterized by visual axes that form a divergent angle The different types of acquired exotropia are intermittent exotropia, sensory exotropia, exotropia with neurologic causesSome people have exotropia from childhood, called a "lazy eye" Others develop it as an adult due to a medical condition like a stroke or thyroid disease Others develop it as an adult when one eye loses vision The eye with poor vision can wander How is
Strabismus occurs when the two eyes are unable to maintain proper alignment and focus together on an object one eye looks directly at the object, while the other eye points in a different direction Accommodative esotropia usually presents itself in children from age 2 and olderExotropia is a type of strabismus (eye misalignment), where one eye turns, or deviates, outward (away from the nose) The deviation may be constant or intermittent, and the deviating eye may always be one eye or may alternate between the two eyes The deviation or eye turn may occur while fixating (looking at) distant objects, near objects, or bothIntermittent esotropia eye turns inward but not all the time (exotropia) According to the This can cause difficulties with measuring
8 rowsINTERMITTENT EXOTROPIA A Major Review Rahul Bhola, MD Exodeviations orManifest intermittent exotropia may increase with time and become constant exotropia Sensory deprivation exotropia Sensory deprivation exotropia is due to disruption of binocular reflexes by acquired conditions like opaque media due to a disease or cataract It begins in children over five years of age or in adultsIntermittent exotropia causes the eye to sometimes move outward, often when you're tired, sick, daydreaming, or looking in the distance Other times, the
Intermittent exotropia (X(T)) is one of the most common form of strabismus with surgery being the mainstay of treatment The main goal of surgery is to preserve binocular vision and stereopsis and to prevent its further loss The decision to operate is mainly based on four aspects increasing angle of exodeviation, deteriorating control of X(T), decrease in stereopsisIntermittent exotropia is sometimes subdivided into 'basic' and 'distance' subtypes but clinical characteristics are very similar for these subtypes of X(T) and, as investigation and management are also essentially the same (Cooper 1977), they are considered together in this review and jointly referred to as 'intermittent exotropia' or X(T)Esotropia can also be due to other conditions Poor vision can cause eye crossing Various neurological conditions (hydrocephalus, stroke, etc) can cause an eye to turn inward A number of medical conditions can cause esotropia ( thyroid eye disease, Duane syndrome, etc)
Intermittent exotropia subject to certain exclusions Patients were excluded if they had any major ocular disease other than intermittent exotropia, severe myopia (greater than −600 diopters D), severe hyperopia (greater than 500 D), age at initial examination younger than 1 year or older than 7 years, or if it was evident at the onset thatMonocular eye closure in sunlight is often noted in patients with intermittent exotropia Neither the reason for eye closure nor its frequency of occurrence in other populations is known We questioned 147 consecutive nonoperated patients (and/or their parents) ages 145 years, 93 with strabismus wiThe angle or control of the deviation may be exacerbated by systemic states including fatigue, systemic illness, or in adults, ingestion of alcohol or other sedatives 2 Additionally, symptoms can be elicited regarding quality of life and difficulty with eye contact and social interactions, as intermittent exotropia has been associated with a decrease in health
Intermittent exotropia, characterized by an acquired, intermittent exodeviation, occurs in approximately 1% of healthy children in the United States 1 and, given its predominance over esodeviations among Asian populations, 2 may be the most prevalent form of strabismus worldwideExotropia is a type of strabismus (misaligned eyes) in which one or both of the eyes turn outward The condition can begin as early as the first few months of life or any time during childhood Exotropia often begins as an intermittent problem, noticed only when the child is tired, sick, just waking up, excited, or stressedChildren with intermittent exotropia commonly close or squint one eye at times, especially when they are exposed to bright sunlight The exact reason people with intermittent exotropia close one eye in bright light remains unknown In any case, when the eye is
Intermittent exotropia (X (T)) is a strabismus condition with outward drifting of either eye interspersed with periods of good alignment or orthotropia (Fig 771) Monocular eye closure may occur during exodeviation Near stereoacuity is often normal during periods of alignment, though it may deteriorate if the condition progressesAim To examine the association of distancenear disparity with neurological disease in children with intermittent exotropia Methods A retrospective analysis was performed of the medical records of all children with intermittent exotropia examined at the Arkansas Children's Hospital between 19 and 02 The study group consisted of children with intermittent exotropia who had aWhen one eye turns inward, outward, upward, or downward, two different pictures are sent to the brain Thus, the brain can no longer fuse the two images coming from the two eyes This causes loss of depth perception and binocular vision The term is from Greek exo meaning outward and trope meaning a turning
Causes of esotropia and exotropia are mostly unknown Children with a family history of the disorder are more likely to get them They are also common in children who have other systemic (chromosomal or neurologic) disorders No known causeWhat is Exotropia Exotropia, a form of Strabismus, is the outward deviation (turn) of an eye and occurs in 12% of children by 7 years of age and occurs equally in males and femalesIn exotropia, one or both eyes turn out What are the symptoms TheThe cause of this condition is not known Most experts believe that the brain of affected patients has trouble controlling the position of the eye Signs and symptoms of intermittent exotropia Abnormal outward movement of the eye happens most often when the child is focusing on distant targets, such as watching television
Intermittent exotropia In this type of strabismus, one eye will fixate (concentrate) on a target while the other eye is pointing outward Symptoms may include double vision, headaches , difficulty reading, eyestrain, and closing one eye when viewing far away objects or when in bright lightDownload PDF Surgical correction of intermittent exotropia is a breadandbutter procedure for many pediatric ophthalmologists But a recent study in the British Journal of Ophthalmology (BJO) 1 and an accompanying editorial 2 call into question the notion that intermittent exotropia is straightforward or fully understood These articles challenge some of the dogma that has guidedGerald M Fenichel MD, in Clinical Pediatric Neurology (Sixth Edition), 09 Exotropia Exotropia is an outward divergence of the eyes It may be intermittent or constant Clinical Features Intermittent exotropia is a relatively common condition that begins before 4 years of age It is most often evident when the child is fatigued and fixating on a far object or in bright sunlight
Exotropia or exoforia Exotropia is a defect that occurs when the eyes are turned outward, which causes a major blurred vision problemExophoria is a type of strabismus and is also known colloquially as wall eyes The exophoria can be congenital o acquired and it is more common in women than in menAn exotropia is an outward eye turn that can have a large variety of presentations It can be intermittent, constant, unilateral, alternating and vary in magnitude An exotropia has a variety of causes, some of which can be life threatening If an eyeturn is suspected or there is a family history of an eyeturn a comprehensive eyeexaminationCommonly referred to as crossed eyes, esotropia is a common type of strabismus in which one or both eyes turn inward toward the nose It is most often identified in children between the ages of 2 and 4, although it can occur at any age The opposite of esotropia is exotropia, which is characterized by eyes that point outward, toward the ears
Treatment of Intermittent Exotropia Treatment options consist of Vision Therapy, patching, eyeglasses and/or, very rarely, surgery The most successful form of treatment is inoffice supervised Vision Therapy with home reinforcement Therapy changes the brain and is directed at the cause and cure of the problemIntermittent exotropia Intermittent exotropia is a common type of strabismus that causes the eye to turn outward This type of eye turn may only be visible during stressful situations or when the person is tired, ill or anxious Advantages of an intermittent eye turnConclusion Overcorrecting minus lens therapy for intermittent exotropia does not appear to cause myopia OVERCORRECTING minus lens therapy has been recommended as a treatment for intermittent exotropia 1 3 By fitting myopic spectacles on hyperopic patients, or spectacles that overcorrect the myopia on myopic patients, accommodative
Exotropia is a type of strabismus characterised by outward deviation of an eye If Exotropia affects both eyes, as a result of which the individual is unable to align both eyes, the condition is termed as convergence insufficiency or exophoria Know the causes, symptoms, treatment, prognosis and complications of exotropiaNonsurgical treatment possibilities include Patching Overminused spectacles or glasses Orthoptic therapy (these exercises will facilitate the rePurpose This study considered whether vergence drives accommodation or accommodation drives vergence during the control of distance exotropia for near fixation High accommodative conve Evidence that convergence rather than accommodation controls intermittent distance exotropia Horwood 12 Acta Ophthalmologica Wiley Online Library
Causes Exotropia occurs when there is an imbalance in the eye muscles or when there is a signaling problem between the brain and the eye Sometimes a health problem, such as cataracts or a stroke, can cause this to occur The condition can also be inheritedThe different types of acquired exotropia are intermittent exotropia, sensory exotropia, exotropia with neurologic causes and field defects, and consecutive exotropia Certain conditions, such as third nerve palsy , thyroid ophthalmopathy , and iatrogenic trauma following retinal detachment surgery or endoscopic sinus surgery, could causeBackground Intermittent exotropia (IXT) is the most common form of childhood exotropia 1, 2 with an incidence of 321 per 100,000 in children under 19 years of age 1 The strabismus is characterized by an exodeviation of one eye that is interspersed with periods of ocular alignment 3 Reliable measurement of the deviation is often hindered by the variable nature of the strabismus,
But when there is a disruption and the muscles do not work together, some form of strabismus, including exotropia, may occur Other causes may involve the nerves that transmit information from the brain to the muscles, or the part of the brain that directs eye movementsMay cause individuals with intermittent strabismus who have the potential for normal binocular vision and older persons who are developing strabismus to alter their activities of daily living
