Others may cross fixate using alternate eyes in the opposite field of gaze, i. Many theories have been postulated regarding the pathogenesis of the disease. Original article contributed by: The standard approach for treatment is bilateral medial rectus recessions which weakens the medial recti the muscles pulling the eyes inward.
DVD is elevation of the non-fixing eye when covered or with visual inattention. Esotropias can be concomitant, where the size of the deviation does not vary with direction of gaze—or incomitant, where the direction of gaze does affect the size, or indeed presence, of the esotropia. Create account Log in. Infantile esotropia is a form of ocular motility disorder where there is an inward turning of one or both eyes, commonly referred to as crossed eyes.
Amblyopia can, however, arise as a result of esotropia occurring in childhood: Thus, in such cases, even when all underlying hyperopic refractive errors have been corrected, the child will continue to squint when looking at very small objects or reading small print. Please help to improve this article by introducing more precise citations. If one eye is turned more frequently than the other, there is increased risk for the development of amblyopia.
Amblyopia is poor vision in an eye that is structurally normal. This alteration between the left and right eye is mostly spontaneous, but may be voluntary in some cases.
Esotropia – Wikipedia
Concomitant esotropia can itself be subdivided into esotropias that are ether constant, or intermittent. In certain circumstances, eye muscle surgery may be indicated to correct the problem.
Ophthalmoparesis Chronic progressive external ophthalmoplegia Kearns—Sayre syndrome. Close follow up is required especially in cross fixating children as amblyopia in one eye usually presents after surgical alignment.
However, in general, management will take the following course:. Are other eye alignment problems associated with infantile esotropia? Do infants with infantile esotropia need glasses?
On the other hand, Chavasse  suggested a primary motor dysfunction, where the associated poor fusion and lack of high-grade stereopsis is probably a sensory adaptation to abnormal visual stimulation during early binocular development caused by the motor misalignment. It is also advised to perform the exam without touching the child if possible. It is the most frequent type of natural strabismus not only in humans, but also in monkeys. Views Read Edit View history. Alternately, a medial rectus recession with an ipsilateral lateral rectus resection can achieve the same effect.
Some ophthalmologists favour an early surgical approach as offering the best prospect of binocularity whilst others remain unconvinced that the prospects of achieving this result are good enough to justify the increased complexity and risk associated with operating on those under the age of one year.
Most patients with “early-onset” concomitant esotropia are emmetropicwhereas most of the “later-onset” patients are hyperopic. May Learn how and when to remove this template message. What is cross fixation? Cataract Congenital cataract Childhood cataract Aphakia Ectopia lentis.
Untreated infantile esotropes can develop excellent vision in each eye, but bifoveal fixation with full binocular function will not be achieved.
What is infantile esotropia? Latent nystagmus may be present. Someone whose squint alternates is very unlikely to develop amblyopia because both eyes will receive equal visual stimulation.
Look up esotropia in Wiktionary, the free dictionary. Recently, botulinum toxin has been used in select cases.

Page Discussion View form View source History. Concomitant esotropias can arise as an initial problem, in which case they are designated as “primary,” endohropia a consequence of loss or impairment of vision, in which case they are designated as “secondary,” or following overcorrection of an initial exotropia in which case they are described as being “consecutive”.
If signs of inferior oblique overaction are noted, surgical weakening of the inferior oblique muscles is usually performed simultaneously. It is, however, associated with other ocular dysfunctions including oblique muscle over-actions, Dissociated Vertical Deviation DVD, Manifest Latent Nystagmusand defective abduction, which develops as a consequence of the tendency of those with infantile esotropia to ‘cross fixate.
The reoperation rate is variable. In a left esotropiathe left eye ‘squints,’ and in a right esotropia the right eye ‘squints. If esotropia is corrected before 2 years of age, there is a better chance of developing the ability to use both eyes together, which is referred to as binocularity. Conjunctivitis allergic Pterygium Pinguecula Subconjunctival hemorrhage. Detailed history taking regarding birth weight, complications of birth, the health of the child and developmental milestones may help in the management of the case.
Link to strabismus surgery entry. Many children will gradually learn to control their esotropias, sometimes with the help of orthoptic exercises. However, where the degree of error is small enough to allow the child to generate clear vision by over-accommodation, but large enough to disrupt their binocular control, esotropia will result. Poor visual acuity will occur in the face of amblyopia. Is infantile esotropia associated with vision loss? There is a hereditary component with infantile occuring much more common in the children of families with monofixation syndrome.
Transactions of the American Ophthalmological Society. The term is from Greek eso meaning “inward” and trope meaning “a turning”.
