Study on the Impact of Refractive Anisometropia on Intermittent Exotropia, Stereopsis, and Amblyopia in Children

Abstract

Objective To preliminarily explore the correlation between different types and degrees of refractive errors and strabismus, amblyopia, and stereopsis. Methods Data from 145 children with refractive errors and 30 children with normal vision were collected. Both groups of subjects underwent routine slit lamp and fundus examinations to exclude other organic eye diseases. Results ① The incidence of strabismus in the refractive error group was higher than that in the normal control group (P < 0.05). ② Far-sightedness and mixed astigmatism were more prone to amblyopia than myopia and regular astigmatism. ③ When the refractive error was ≥ 1.00D, far stereopsis and random dot static 0-order stereopsis decreased, while near stereopsis Titmus showed no statistical difference. Conclusion Different types and degrees of refractive errors have different clinical features of strabismus and amblyopia. Among the three stereopsis examination methods, far stereopsis and random dot static 0-order stereopsis are more sensitive than near stereopsis and can better reflect damages to fine stereopsis.
