Simulated Hyperopic Anisometropia and Reading, Visual Information Processing, and Reading-Related Eye Movement Performance in Children

  • The purpose of this study was to assess the prevalence and associated factors of refractive error among primary school children.

  • This study included 16 children (mean age: 11.1 ± 6 0.8 years) with minimal refractive error.

  • Simulated hyperopic anisometropia and sustained near work both independently reduced performance on all of the outcome measures (P < 0.001).

  • There was a significant interaction between simulated anisometropia and near work (P < 0.05).

  • There was a greatest reduction in performance during simulated anisometropia in combination with sustained near work.

  • Laterality of the refractive error simulation (ocular dominance) did not significantly influence the outcome measures (P > 0.05).

  • There was a decrease of up to 12% in performance across the range of academic related measures following sustained near work undertaken during the anisometropic simulation.

  • Simulated hyperopic anisometropia significantly reduced academic-related performance, mainly in combination with sustained near work.

This article was identified as a reference for a VII-commissioned systematic review on the Impact of URE on Children.
