KEY HIGHLIGHTS:

  • The purpose of this study is to determine the prevalence of refractive errors in Colombia and its relations with demographic and socioeconomic variables.

  • A cross-sectional study performed in 10 Colombian administrative districts (MIOPUR study), including children and adolescents from 8 to 17 years old and adults from 35 to 55 years old.

  • 3608 individuals (100% of whom agreed to participate) were included. Prevalence estimates of refractive errors were: hyperopia 32.3% , myopia 12.9% , mixed astigmatism 2.8%  and anisometropia 1.9% .

  • Prevalence of myopia in 15-year-old adolescents was 14.7%.

  • In children and adolescents, the hyperopia prevalence decreased while myopia prevalence increased with age.

  • In the adults group, the tendency was the contrary.

  • Myopia prevalence reached 15.7% in urban and 9.2% in rural areas, and for hyperopia, the rates were 29.4% in urban and 36.1% in rural areas.

  • In the multivariate analysis, living in an urban area significantly increased the risk of having myopia.

  • There were significant regional differences among diverse zones of the country.

  • Prevalence estimates of myopia and hyperopia in Colombia were found to be at an intermediate point compared with global data.

  • In adults, myopia frequency was lower than in European and Asian studies.

  • The prevalence of myopia increased during childhood and adolescence and was higher in middle-aged adults (35-39 years) than in older adults. On the other hand, hyperopia rates increased with age, findings that suggest a cohort effect.

  • In the multivariate analysis, residence in urban areas and living in a medium-high socioeconomic status were linked to myopia.
