KEY HIGHLIGHTS:

  • The purpose of this study was to assess the prevalence of refractive errors in school-age children in Morocco.

  • This was a cross-sectional study conducted with 545 children aged 6 to 16 years.

  • Only 6.1% of the children registered a myopic refractive error in at least one eye.

  • The prevalence of bilateral myopia was 3.1%.

  • The prevalence of hyperopia was 18.3%.

  • Bilateral hyperopia was present in the 11.7% of the total children.

  • The study found 23.5% of children presented astigmatism in at least one eye.

  • Bilateral astigmatism was present in 9.7% of the children.

  • Anisometropia was present in 2.9% of children.

  • There was a low prevalence of myopia in these African children, astigmatism being the most frequent refractive error.
