The prevalence of astigmatism in Spanish children decreases significantly with age. Astigmatism types also shift, with

Area of Science:

  • Ophthalmology
  • Pediatric Optometry
  • Public Health

Background:

  • Astigmatism is a common refractive error affecting visual acuity.
  • Understanding its prevalence in pediatric populations is crucial for early intervention.
  • Previous studies show varying prevalence rates across different ethnicities and environments.

Purpose of the Study:

  • To determine the prevalence of astigmatism in infants and children within a Spanish population.
  • To analyze age-related changes in astigmatism prevalence and axis orientation.

Main Methods:

  • Examined 478 children aged 2-12 years with astigmatism in Valencia Province, Spain.
  • Classified participants into age-specific groups.
  • Measured astigmatism error and axis orientation using noncycloplegic retinoscopy.

Main Results:

  • Overall astigmatism prevalence (> or = 1.00 diopter) declined from 44.3% to 5.2% with increasing age.
  • Prevalence of against-the-rule astigmatism decreased from 61.5% to 33.4% between ages 2 and 12.
  • With-the-rule astigmatism increased from 23.1% to 66.6%, while oblique astigmatism decreased with age.

Conclusions:

  • The observed prevalence and age-related trends of astigmatism in this Spanish cohort align with international findings.
  • Factors like race, nutrition, and environment do not appear to significantly alter these trends compared to existing literature.
  • This study reinforces the understanding of astigmatism's natural progression during childhood.
