Esotropia – Signs, Causes, and Treatment

Written by Michael Garin O. Medically reviewed by Dr. Ashley Roth. Exotropia also known as wall-eye or divergent strabismus differs from its opposite form, esotropia eye turns afunika toyi tomato mp3 download toward nosein that exotropic eyes point outward or away from the nose.

Exotropia can occur in one or both eyes. Although exotropia can appear at any age, it commonly appears between the ages of one and four. Exotropia can also be classified by cause—it can be either congenital present at birth; also known as infantile exotropia or acquired. Acquired exotropia is found in females more than males; 63—70 percent of all adult cases are women. It is more common in the Middle East, Africa, and Asia, and at latitudes where there are higher levels of sunlight.

It is less common in the United States and Europe. In most cases, the first signs of exotropia appear during childhood. Typically, it begins intermittently; occurring while the child is staring into space or daydreaming. The deviation may become more noticeable while the child is staring at something from a distance. Most strabismic children do not know they have vision problems.

Exotropia in Children and Adults

Sadly, they think problems such as double vision or nearsightedness are normal and do not express their inability to see clearly because they do not know any better. Because of this, it is important to watch children for symptoms of all eye conditions, including exotropia. Intermittent exotropia is detectable after six months of age, and is considered a progressive disorder that can lead to constant exotropia if left untreated. Normally, these muscles work together, sending signals to the brain and directing eye movements so that both eyes can focus on the same object.

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 movements. Eye injuries, head trauma, and other general health conditions can also cause exotropia. Parents and other family members are typically the first people to notice exotropia in a child. When exotropia is suspected in an infant, the eye doctor will shine a light into the eyes to see if the light reflects back from the same location on each cornea.Written by Michael Garin O.

Medically reviewed by Dr. Trent Albright. Commonly 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 exotropiawhich is characterized by eyes that point outward, toward the ears. The degree of esotropia may vary from small-angle hardly noticeable to large-angle very noticeableand the condition may be characterized as congenital meaning that the affected person is born with it or acquired. The primary sign of esotropia, obviously, is crossing of the eyes. Habitual squinting or constantly rubbing one eye are also common signs. If your child suffers from this condition, he or she may also complain of double vision.

Crossed eyes can be constant or intermittent. A constant esotropia is present all the time, whereas intermittent esotropia may become apparent only when looking at close objects or only when looking at distant objects, or if the affected person is tired or sick. Intermittent esotropia often requires treatment to prevent it from becoming constant.

As indicated above, esotropia is either congenital or acquired. Congenital esotropia also known as infantile esotropia is usually detected during the first six months of life. Infants with esotropia are otherwise developmentally and neurologically normal.

Acquired or secondary esotropia, which develops later in life, can occur for a variety of reasons:.

Crossed eyes can be hereditary, although it may occur differently in different family members. It is also associated with prematurity and various neurological and genetic disorders. Farsightedness is the most common vision problem associated with esotropia. Some systemic disorders, such as hyperthyroidism and diabetes, cause ocular misalignment. The appearance of crossed eyes in an infant is not always a sign of esotropia; it can be a result of the shape of the eyelids or nasal bridge, and as the infant grows, the misalignment goes away.

This is called pseudostrabismus. This includes an evaluation of the general health of the eyes and their refractive state that is, whether the child is farsighted, nearsightedor has astigmatism. The eyes will be dilated with eye drops to determine the degree of farsightedness. The ophthalmologist or optometrist will pay close attention to whether the acuity is equal in both eyes or if one eye is stronger than the other.

If there is a strong preference for one eye over the other, amblyopia may occur. Amblyopia occurs when one eye fails to properly communicate visual images to the brain, and it is best treated at an early age. It can sometimes be treated by patching the stronger eye, but in some cases more aggressive methods of treatment are necessary. If ocular misalignment is detected, the degree of misalignment is measured so that the child can be fitted with the appropriate glasses. Glasses should be worn all the time.

Children whose eyes cross even when they are wearing glasses or contact lenses may benefit from a bifocal lens. Surgery is rarely necessary, but may be considered if eye glasses fail to straighten the eyes. Surgery does not eliminate the need for glasses; it simply reduces the degree of eye crossing. The goals of treatment are to re-establish ocular alignment, maximize binocular vision, relieve any double vision, and manage any associated amblyopia.

If amblyopia is present and surgery is being considered, it is best to address the amblyopia with eye-patch therapy before surgery is performed. Esotropia cannot be prevented, but complications resulting from it can be prevented if the problem is detected early and treated properly.

Children should be monitored closely during infancy and through the preschool years to detect potential eye problems, especially if a relative has strabismus. In the United States, children are typically screened for eye health before they are six months old, and thereafter at each check-up with their pediatrician or family practitioner.Commonly described as crossed eyes, esotropia is a common type of strabismus in which one or both eyes turn inward toward the nose.

It is frequently identified in children between the ages of 2 and 4, although it can take place at any age. The reverse of esotropia is exotropia, which is characterized by eyes that point external, towards the ears. The degree of esotropia might differ from small-angle hardly visible to large-angle very visibleand the condition may be identified as congenital significance that the affected person is born with it or gotten.

The primary sign of esotropia, obviously, is crossing of the eyes. Regular squinting or continuously rubbing one eye are also typical signs. If your child suffers from this condition, he or she might likewise suffer double vision. Crossed eyes can be consistent or periodic. A consistent esotropia exists all the time, whereas periodic esotropia might emerge just when taking a look at close things or only when taking a look at distant items, or if the impacted individual is tired or sick.

Periodic esotropia typically needs treatment to prevent it from ending up being consistent. As shown above, esotropia is either genetic or obtained. Genetic esotropia also referred to as infantile esotropia is normally detected during the first six months of life.

Infants with esotropia are otherwise developmentally and neurologically normal. Gotten or secondary esotropia, which establishes later in life, can take place for a variety of factors:. Crossed eyes can be genetic, although it may take place differently in various member of the family. It is likewise related to prematurity and numerous neurological and genetic disorders.

Farsightedness is the most common vision problem associated with esotropia. Some systemic conditions, such as hyperthyroidism and diabetes, cause ocular misalignment. The look of crossed eyes in an infant is not always a sign of esotropia; it can be a result of the shape of the eyelids or nasal bridge, and as the baby grows, the misalignment goes away.

This is called pseudostrabismus. This includes an examination of the basic health of the eyes and their refractive state that is, whether the child is farsighted, nearsighted, or has astigmatism. The eyes will be dilated with eye drops to determine the degree of farsightedness. The eye doctor or optometrist will pay attention to whether the acuity is equal in both eyes or if one eye is more powerful than the other.

If there is a strong choice for one eye over the other, amblyopia might take place. Amblyopia takes place when one eye fails to effectively interact visual images to the brain, and it is best dealt with at an early age. It can often be dealt with by covering the more powerful eye, however in some cases more aggressive approaches of treatment are necessary.

If ocular misalignment is detected, the degree of misalignment is measured so that the child can be fitted with the suitable glasses. Glasses must be used all the time. Children whose eyes cross even when they are wearing glasses or contact lenses may take advantage of a bifocal lens.

Surgery is hardly ever necessary, however may be considered if eye glasses fail to align the eyes. Surgery does not eliminate the need for glasses; it simply lowers the degree of eye crossing. The objectives of treatment are to re-establish ocular alignment, take full advantage of binocular vision, alleviate any double vision, and manage any involved amblyopia. If amblyopia is present and surgery is being considered, it is best to resolve the amblyopia with eye-patch therapy prior to surgery is performed.

Esotropia can not be avoided, however complications arising from it can be prevented if the problem is discovered early and dealt with appropriately.However, constant crossing of the eyes may be a concern. When an eye crosses inward it is termed esotropia. Esotropia is a type of strabismus. An esotropia can occur in just one eye or alternate between both eyes. It is rare for both eyes to cross in at the same time.

The cause of an esotropia depends on when it first occurs. In adults, a sudden onset of esotropia can be a sign of a very serious condition. However, there are other causes. Below 4 to 5 months of age, intermittent crossing is usually normal and is just a sign of learning how to use the eyes together as a system. Some babies and ethnic groups may have pseudo-strabismus. This is a condition in which the bridge of the nose is not fully developed or flatter than normal. Congenital esotropia usually appears very early between 2 to 4 months and the size of the deviation or eye turn tends to be very large.

Often, infants with congenital esotropia do not have a large amount of farsightedness or nearsightedness. The best way to correct congenital esotropia is with surgery. Surgery is not aimed at providing a way for the eyes to work together in a normal fashion but rather to correct the deviation to have a better cosmetic appearance.

The eyes may still not work perfectly together, but the child will have a much improved cosmetic appearance. Accommodative esotropia : Accommodative esotropia occurs around age 2. It is usually caused by a problem with the two systems that control our eye muscles and the amount our eyes focus. The accommodative system focusing system allows our eyes to change power and focus so that objects remain clear no matter the distance.

When we look far away, our eyes are straight. When we look at something very close, our eyes converge or turn in and our eyes increase their focusing power. When we look back to a distance, we relax our focusing power and the eyes become straight again. Young children have huge amounts of focusing power. As a result, when a child has a very large amount of uncorrected farsightedness, the child attempts to make things clear by over-focusing.

To achieve that, they have to focus a great deal to compensate for the uncorrected vision problem. When they focus this much, the binocular and focusing systems begin to get mixed signals. Usually, one eye will turn in.Acute acquired comitant esotropia AACE can be a diagnostic challenge for ophthalmologists and neurologists because of its association with neurological pathologies.

Our study describes a series of adult patients with AACE of undetermined etiology. Data on the clinical findings of patients presented with AACE of undetermined etiology with a minimum follow-up of 1 year were retrieved from the medical records and the results analyzed. A series of 9 esotropia cases age range: 20—43 years was reviewed. All patients had full duction and versions, without an A-pattern or V-pattern. All patients had esotropia for distance and near.

Neurological evaluation in all cases was normal. Among patients, 3 were treated with prisms, 4 were treated with strabismus surgery, and 1 was treated with botulinum toxin injections; 1 patient declined treatment. In treated patients posttreatment sensory testing indicated restoration of binocularity that remained stable throughout follow-up of 1—9 years. The patient that declined treatment had binocular function with base-out prisms.

Acute onset esotropia may be seen without a neurological pathology in adults. Good motor and sensory outcomes can be achieved in these patients with AACE of undetermined etiology via surgical and nonsurgical methods. Acute acquired comitant esotropia AACE is an unusual presentation of esotropia that occurs in older children and adults.

AACE is characterized by acute onset of a relatively large angle of esotropia, along with diplopia and minimal refractive error [ 12 ].

AACE is not cyclical, although it may initially be intermittent. It is comitant at distance and near fixation [ 1 ].

Acute Acquired Comitant Esotropia in Adults: Is It Neurologic or Not?

AACE is categorized as 3 types, based on the clinical features and apparent etiology: type 1 Swan type : acute onset esotropia following occlusion; type 2 Franceschetti type : refractive error which is minimal hypermetropia without an accommodative element; type 3 Bielschowsky type : AACE associated with myopia [ 34 ].

The other causes of acute esotropia in adults include sixth nerve palsy, age-related distance esotropia, divergence palsy, accommodative esotropia, decompensated monofixation syndrome, restrictive strabismus, consecutive esotropia, sensory strabismus, ocular myasthenia gravis, and some neurological disorders tumors of the cerebellum, brainstem, pituitary region, corpus callosum, Arnold-Chiari malformation, cerebellar disease, and idiopathic intracranial hypertension.

AACE is considered rare, but no statistical data is available regarding its actual incidence or prevalence [ 5 ].

We present 9 patients with AACE of undetermined etiology and a review of the relevant literature. The medical records of 9 consecutive patients older than 18 years of age presenting with acute acquired comitant esotropia of undetermined etiology between and and with a minimum follow-up of 1 year were reviewed retrospectively.

The authors adhered to the tenets of the Declaration of Helsinki. All patients underwent ophthalmological, neurologic examinations and orbital-cranial MRI with contrast for inclusion. An ophthalmologist and neurologist performed the examination. Patients with incomitant esotropia were excluded. Incomitance was defined as limited abduction and larger deviation at lateral gaze. The following information was obtained on each patient: sex, age, presenting complaint, duration of symptoms, signs, cycloplegic refraction with cyclopentolate, best corrected visual acuity, deviation at near and distance, fusion and stereopsis, neurological examination and tests, cranial and orbital MRI findings, treatment, follow-up time, and outcomes.

Snellen chart was used to test visual acuity. The angles of deviations were assessed by alternate cover prism and cover test in all 9 cardinal gaze positions.

Both near and distance measurements were taken.

Ocular motility, patterns, and nystagmus were evaluated clinically. Lees screen test was performed. The 9 patients presented with acute onset of binocular horizontal diplopia that developed 10 days—18 months prior to presentation.

Diplopia was constant throughout the day in all cases. Case details are given in Table 1. The 5 female and 4 male patients were aged 20—43 years. None of the patients had a history of recent trauma, occlusion of one eye, or recent illness. The medical history in all cases was unremarkable.Michael Garin Nov 29, Optometry.

Treatment of Intermittent Exotropia. Exotropia -- a common type of strabismus -- is the outward deviation of an eye eye turns away from the nose.

When the eye turns outward only some of the time, it is called intermittent exotropia. Most exotropia is intermittent. In many cases, the eye turn might only be visible during stressful situations or when the person is tired, ill or anxious. Pros: Advantages of Intermittent Eye Turn When the eye turn is only occasional, the visual system including the brain still has many opportunities to develop. That is, as long as the eyes are straight some of the time, the brain and two eyes will develop some normal functioning binocular vision and depth perception.

Consequently, good possibilities for the development of improved vision in the future will still be present. Cons: Disadvantages of Intermittent Eye Turn When the eye turn happens some of the time, but not all the timethe outside observer s might conclude that there is no serious problem and fail to seek help.

Or they might think the person is simply daydreaming, lazy, or not paying attention. Even worse, without knowing that there is a physical problem, the observer might feel uneasy or mistrustful of the person with intermittent exotropia who gives poor eye contact and comes off as distracted or "shifty-eyed.

For example, the parents might notice the child's occasional eye turn, bring the kid in for an exam, and then the eye doctor won't be able to find it or induce it.

In that case, the eye turn is not showing up during the "command performance" of the eye exam because the child is making an extra effort to pay attention, be "on good behavior," please the adults, etc. This in not unlikely with the child who only has the eye turn when fatigued, ill, etc.

Miscellaneous clue: children with intermittent exotropia often close their eye in bright sunlight. Treatment of Intermittent Exotropia Treatment for intermittent exotropia does not have to occur immediately. Since the brain and eyes work properly some of the time, time is on your side.

As a matter of fact, early surgery has the potential of disturbing the ability of the brain for fusion in the future and can cause a permanent reduction in vision amblyopia. The most successful form of treatment is in-office supervised Vision Therapy with home reinforcement.

Therapy changes the brain and is directed at the cause and cure of the problem. Surgery should be used as a last resort only for the large angle intermittent exotropes and only after in-office Vision Therapy not been as successful as expected. In those cases, surgery will probably only yield cosmetic benefits.
