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. [24] Another study found that for children with infantile esotropia early surgery decreases the risk of dissociated vertical deviation developing after surgery. [25]
Most patients with "early-onset" concomitant esotropia are emmetropic, whereas most of the "later-onset" patients are hyperopic. It is the most frequent type of natural strabismus not only in humans, but also in monkeys. [3] Concomitant esotropia can itself be subdivided into esotropias that are either constant, or intermittent. Constant esotropia
Some consider botulinum injections to be a treatment option for children with small- to moderate-angle infantile esotropia. [7] [8] Studies have provided indications that performing injections into both medial rectus muscles may be more effective than an injection into one medial rectus muscle alone. [2]
Adult and child observers perceived a right heterotropia as more disturbing than a left heterotropia, and child observers perceived an esotropia as "worse" than an exotropia. [22] Successful surgical correction of strabismus, for adult as well as children, has been shown to have a significantly positive effect on psychological well-being. [23] [24]
There is tentative evidence that children with infantile esotropia achieve better binocular vision post-operatively if the surgical treatment is performed early (see: Infantile esotropia). A recent study reported the reoperation rate in a sample of over 6000 patients being 8.5%. [13]
Blurring of distance vision: Intermittent blurring of distant vision after prolonged near work is the main symptom of pseudomyopia. Asthenopia; Headache; Eyestrain; Photophobia [1] Esotropia: Acute onset esotropia may occur in accommodative spasm, which is the common cause of pseudomyopia. [2] Diplopia: Diplopia may occur due to esotropia or ...

Secondary MFS is a frequent outcome of surgical treatment of congenital esotropia. [2] A study of 1981 showed MFS to result in the vast majority of cases if surgical alignment is reached before the age of 24 months and only in a minority of cases if it is reached later. [5] MFS was first described by Marshall Parks. [3]
