Abstract
Analysis of Improvement Time and Influencing Factors of Diplopia after Intermittent Exotropia in Children.
Highlights
Intermittent exotropia is a type of strabismus between recessive and concomitant exotropia, which is one of the common clinical types of ophthalmopathy
After strabismus, the same object is projected on the noncorresponding point of the retina of both eyes; that is, it is projected on the central fovea and the peripheral retina of the strabismus eye, the object image of the fovea is in front, and the object image of the peripheral retina is in another visual direction, so one object image is perceived as two objects [9]
Monocular diplopia is caused by an object falling on two different parts of the retina of one eye at the same time, while binocular diplopia is triggered by a deviation in one eye, which induces one object to fall on the noncorresponding point of the retina of both eyes at the same time. at is, one image falls on the macular fovea of the fixed eye, while the other falls on the retina around the fovea of the strabismus eye [10]
Summary
Intermittent exotropia is a type of strabismus between recessive and concomitant exotropia, which is one of the common clinical types of ophthalmopathy. E frequency and angle of intermittent strabismus in children can rarely be improved by themselves and can often be transformed into constant or alternating exotropia after delaying the opportunity of treatment, resulting in the loss of binocular visual function [8]. Monocular diplopia is caused by an object falling on two different parts of the retina of one eye at the same time, while binocular diplopia is triggered by a deviation in one eye, which induces one object to fall on the noncorresponding point of the retina of both eyes at the same time. In order to observe the incidence, improvement time, and influencing factors of postoperative diplopia in children with intermittent exotropia, 135 children with intermittent exotropia who underwent intermittent exotropia surgery in our hospital from February 2019 to April 2021 were analyzed retrospectively
