Infantile Esotropia — AAPOS
If one eye is turned more frequently than the other, there is increased risk for the development of amblyopia. All children with these or other risk factors should be evaluated by an ophthalmologist. Incomitant esotropias are conditions in which the esotropia varies in size with cnogenita of gaze. A second type of accommodative esotropia also exists, known as ‘convergence excess esotropia. The person with hyperopia, in an attempt to “accommodate” or focus the eyes, converges the eyes as well, as convergence is associated with activation of the accommodation reflex.
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. Amblyopia occlusion treatment after the eyes are aligned can interfere with the exercise of binocularity. Conjugate gaze palsy Convergence insufficiency Internuclear ophthalmoplegia One and a half syndrome. Cognenita 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.
This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. Surgery performed prior to 2 years of age has been found to give better visual prognosis.
Occasionally a vertical acting eye muscle inferior oblique may overact which may cause the eye to move up when looking to the side. Retrieved from ” http: Understanding visual milestones and anatomic development is envotropia for precise visual assessment of the child. However, some surgeons may opt to surgically realign the eyes prior to amblyopia therapy if strabismic amblyopia is suspected.
Fortunately, accommodative esotropia can usually be treated with spectacles. May Learn how and when to remove this template message.

It is possible to encourage alternation through the use of occlusion or patching of the ‘dominant’ or ‘fixating’ eye to promote the use of the other.
Some children develop a slowly increasing outward drift of congenjta eyes called exotropia. The reoperation rate is variable. This can be done by engaging the patient through the use of colorful toys, whistling and making noises. This is a small, rhythmic, horizontal movement of the eyes when one eye is closed or covered.
Stability of the esotropia angle is assessed prior to surgical intervention. Early re-alignment has been shown to lead to improved sensory outcomes.
Many children will gradually learn to control their esotropias, sometimes with the help of orthoptic exercises.
Unilateral vision may be decreased by the nystagmus but bilateral vision vision with both eyes open is typically not affected. The prognosis for each patient with esotropia will depend upon the origin and classification of their condition. For example, the right eye moves up when it looks toward the nose.
Surgery is performed when any associated amblyopia has been treated and the amount of esotropia is stable. Children with infantile esotropia are usually not more nearsighted or farsighted than those without crossing.
Alternately, a medial rectus recession with an ipsilateral lateral rectus resection can achieve the same effect. Most patients with “early-onset” concomitant esotropia are emmetropicwhereas most of the “later-onset” patients are hyperopic. Infantile esotropia is usually treated with strabismus surgery eye muscle surgery.

Botulinum toxin injection into the medial recti to weaken them has also been used, but studies have shown mixed sensorimotor outcomes when compared to traditional incisional surgery. Complete sensory evaluation in a preverbal child is difficult.
The vast majority of esotropias are primary. Optokinetic response to detect smooth pursuit and saccade eye movements will aid conegnita the diagnosis of amblyopia. Where the degree of hyperopia is large, the child may not be able to produce clear vision no matter how much extra-accommodation is exerted and thus no incentive exists for the over-accommodation and convergence that can give rise to the onset of esotropia.
