Accommodative esotropia manifests as eye inturning secondary to the increased work of focusing through significant hypermetropia. Untreated, children with infantile esotropia can develop good vision in each eye, but bifoveal fixation with full binocular function will not be achieved. Re-operation may be required months or years after the initial surgery. Surgery was successful in 10 (38%) of 26 patients after 1 surgery and in an additional 13 (50%) of 26 patients after a second surgery. [9] Amblyopia, residual esotropia or consecutive persistent exotropia may develop and should be addressed early to get the best possible visual and fusion potential. Comparison of clinical features between two different types of exotropia before 12 months of age based on stereopsis outcome. In: Wright KW. Developmental assessments were obtained at each visit. A Dutch study (ELISSS)[21] compared early with late surgery in a prospective, controlled, non-randomized, multicenter trial and reported that: Children operated early had better gross stereopsis at age six as compared to children operated late. Some ophthalmologists, notably Ing [16] and Helveston,[17] favour a prescribed approach often involving 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. It occurs because the brain ignores input from an eye. [8], 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. The angle of deviation is constant and large (>30 PD). In our study cohort, age of onset ≤6 months was associated with worse sensory prognosis for children with infantile exotropia but not with a difference in motor outcomes. Infantile esotropia. Biglan et al.1 also reported an initial success rate of 60% in 10 patients with a minimum follow-up of 4 years. Binocular status after surgery for constant and intermittent exotropia. Journal of American Association for Pediatric Ophthalmology and Strabismus, https://doi.org/10.1016/j.jaapos.2019.08.275. Govindan M, Mohney BG, Diehl NN, Burke JP. The timing of amblyopia treatment in relation to eye muscle realignment surgery is debatable. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. The clinical records of patients who presented with constant infantile exotropia of >25Δ and subsequently underwent strabismus surgery at a single center from 2004 to 2014 were reviewed retrospectively. Early surgery for congenital esotropia. J AAPOS. Patients who developed consecutive esotropia were younger at the time of initial operation (P = 0.039). Occasionally a vertical acting eye muscle (inferior oblique) may overact which may cause the eye to move up when looking to the side. Ocular rotationSome infants may show some limitation of abduction upon initial examination of eye movements as a result of cross fixation. However, some surgeons may opt to surgically realign the eyes prior to amblyopia therapy if strabismic amblyopia is suspected. Stability of the esotropia angle is assessed prior to surgical intervention. Many theories have been postulated regarding the pathogenesis of the disease. [J Pediatr Ophthalmol Strabismus. Corneal light reflex tests (Hirshberg and Krismky) can be helpful estimating angle of deviation, but cover testing should be employed when possible. Esotropia between 10 and 90 dioptres in size, Either alternation or fixation preference may be present (if the latter then. As mentioned previously, the angle of deviation is usually larger than 30 PD, and it is constant. 655 Beach StreetSan Francisco, CA 94109-1336Phone: (415) 561-8505Fax: (415) 561-8531. The patient cross-fixates, that is, to fixate objects on the left, the patient looks across the nose with the right eye, and vice versa. However, doll’s head maneuver, in which gentle spinning of the child stimulates a vestibular movement to the opposite direction of the spin and a refixation saccade in the same direction, full abduction can be elicited.
