Infantile esotropia manifests before a child is 6 months old and includes a constant, large angle of strabismus, no or mild amblyopia, latent. Strabismus is one of the most relevant health problems of the world, and infantile esotropia is perhaps the most visually significant yet the least. The term congenital esotropia is often used interchangeably with infantile esotropia, but few cases are actually noted at birth. Often the exact.

Age 2 months Visual Acuity without correction: It is essential that a child with strabismus is presented to the ophthalmologist as early as possible for diagnosis and treatment in order to allow best possible monocular and binocular vision to develop. Endotropua 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.
A pattern of cross-fixation does not infer spontaneous or equal alternation or the absence of infahtil. Pre-operative photo demonstrating the large angle esotropia, age 6 months At 6 months of age, she underwent uncomplicated bilateral medial rectus recessions Fortunately, accommodative esotropia can usually be treated with spectacles.
Duane Syndrome Patients with esotropic Duane syndrome have limited abduction with small-angle esotropia in primary gaze, abnormal face turn, and incomitance. Nystagmus is also frequently observed and is usually latent type. Occasionally a vertical acting eye muscle inferior oblique may overact which may cause the eye to move up when looking to the side. What is infantile esotropia?
Patients with infantile esotropia are typically neurologically normal, have hyperopia less than 3. Accomodative esotropia manifests as eye inturning secondary to the increased work of focusing through significant hypermetropia.
However, if farsighted, spectacles may be prescribed. Views Read Edit View history.
As alternative to surgery, also botulinum toxin therapy has been used in children with infantile esotropia. Also, latent nystagmus occurs in up to one third of patients with a history of early-onset esotropia Endortopia, Equally round and briskly reactive. A recent study on 38 children concluded that surgery for infantile esotropia is most likely to result in measureable stereopsis if patient age at alignment is not more than 16 months. This debate relates to the technical anatomical difficulties of operating on the very young versus the possibility of an increased potential for binocularity associated with early surgery.
Multiple studies have shown that surgery done before two years of age results in better binocular vision and stereopsis. Congenital fibrosis of the extraocular muscles Patients with congenital fibrosis of the nifantil muscles will frequently have poor ductions. It is a specific sub-type of esotropia and has been a subject endotropiw much debate amongst ophthalmologists with regard to its naming, diagnostic features, and treatment.
Many theories have been postulated regarding the pathogenesis of the disease. What information can we give to the patient about the risks of strabismus surgery. DVD dissociated vertical deviationinferior oblique overaction, and latent nystagmus. This page was last edited on 20 Octoberat However, some surgeons may opt to surgically realign the eyes prior to amblyopia therapy if strabismic amblyopia is suspected.
Intraocular infection is rare following strabismus surgery Patients should be followed closely for amblyopia, even if they achieve good motor alignment. Infantile esotropic patients will frequently have normal vision in each eye, so any patient with suspected infantile esotropia and poor vision should undergo a complete and thorough eye exam to rule out cause for poor vision.
However, most cases of infantile esotropia will require surgical intervention. These more recent findings formed the basis for the enodtropia practice of early surgery for patients with congenital esotropia. 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.

Some prefer to use the term infantile esotropia to more accurately reflect the typical postnatal onset of misalignment Nelson, The treatment of infantile esotropia is extraocular muscle surgery.
Similar to restrictive esotropia, patients endotrkpia frequently have an anomalous head posture and incomitance. J Pediatr Ophthalmol Strabismus. Normal-appearing optic nerves with cup-to-disc ratios of 0. Summary Constant esodeviation manifest by 6 months of age Typically, large angle deviations ranging from prism diopters Low amount of hyperopia endotrolia. Study outcomes have indicated that after surgery the child catches up in development of fine-motor skills such as grasping a toy and handling a bottle and of large-muscle skills such as infanti, standing, and walking in case a developmental delay was present before.
Early re-alignment has been shown to lead to improved sensory outcomes. Parks has noted that primary monofixation intantil occurs 11 times more frequently among first-degree relatives of patients with infantile esotropia than the general population.
Close attention needs to be paid to the point at which the alternation occurs. Unilateral vision may be decreased by the nystagmus but bilateral vision vision with both eyes open is typically not affected.
The reoperation rate is variable. Claude Worth believed that infantile esotropia was a congenital defect in fusion invantil, suggesting that despite correction, patients with infantile esotropia could never achieve good binocular vision. Strube 19 November They also have palpebral fissure narrowing of the affected eye on adduction. This remains undetermined at the present time.
Forced duction testing can be helpful in infqntil the diagnosis in this situation. Post-operative gaze photos showing preservation of good motility. C refers to centrality and can be assessed by the location of the corneal light reflex as the patient looks at the examiner’s light with the opposite eye occluded.

Some ophthalmologists, notably Ing  and Helveston,  favour a prescribed approach often infanhil multiple surgical episodes whereas others prefer to aim for full alignment of the eyes in one procedure and let the number of muscles operated upon during this procedure be determined by the size of the squint.
