Prevalence of Refractive Errors Among School Children in Northeastern Iran

  • The purpose of this study was to determine the prevalence of refractive errors among schoolchildren in Northeastern Iran by age and gender.

  • The prevalence rates of myopia, hyperopia and astigmatism were 4.3% (95%CI: 3.3–5.3), 5.4% (95%CI: 4.3–6.5) and 11.5% (95%CI: 9.9–13.1) respectively and were not related to gender.

  • The prevalence of myopia in schoolchildren in Northeastern Iran is considerably lower than that of East Asian populations, but similar to many other populations, including South Africa, Chile and other countries of the Middle East.
