Clinical Report: Myopia Patterns in Intermittent Exotropia

Overview

A nationwide study of 2,744 children with intermittent exotropia (IXT) reveals that while they do not exhibit a significantly higher incidence of myopia compared to peers, they have a notably increased prevalence of anisometropia as they age.

Background

Intermittent exotropia is a common form of childhood strabismus, particularly prevalent in East Asia, where myopia rates are also high. Understanding the refractive profiles of children with IXT is crucial.

Data Highlights

Key Findings

• Children with IXT show a higher prevalence of anisometropia compared to the general population.
• No significant difference in the incidence of myopia was found between children with IXT and their peers.
• Age-specific refractive error distributions in the IXT cohort mirrored those of the general population.
• Non-dominant eyes in children with IXT became progressively more myopic than dominant eyes after age nine.

Clinical Implications

The study indicates that clinicians should be aware of the increased risk of anisometropia in children with IXT.

Conclusion

The findings provide new insights into the refractive characteristics of children with intermittent exotropia.
