KEY HIGHLIGHTS:

  • The purpose of this study was to assess the prevalence of refractive errors and vision impairment in school-age children in a suburban area of Santiago, Chile.

  • A total of 6998 children from 3830 households were randomly selected, and 5,303 children (75.8%) were examined.

  • The prevalence of uncorrected, presenting, and best visual acuity 0.50 (20/40) or worse in at least one eye was 15.8%, 14.7%, and 7.4%, respectively.

  • 3% participants had best visual acuity 0.50 or worse in both eyes.

  • Refractive error was the cause in 56.3% of the 1,285 eyes with reduced vision, amblyopia in 6.5%.

  • Hyperopia 2.00 diopters or greater decreased from 22.7% to 7.1% in males and from 26.3% to 8.9% in females.

  • Females had a significantly higher risk of hyperopia than males.

  • Refractive error, associated primarily with myopia, is a major cause of reduced vision in school-age children in La Florida.
