Summary

Refractive errors like hyperopia and myopia are common in older adults, with prevalence varying by age and gender. Higher education was linked to myopia in men, indicating complex associations in this population.

Area of Science:

  • Ophthalmology
  • Gerontology
  • Epidemiology

Background:

  • Refractive errors are a significant public health concern, particularly in aging populations.
  • Understanding the prevalence and associated factors of refractive errors is crucial for eye care management in older adults.

Purpose of the Study:

  • To determine the prevalence of myopia, hyperopia, and emmetropia in an older Australian population.
  • To investigate the associations between refractive errors and age, gender, and education level.

Main Methods:

  • A cross-sectional study involving 3654 residents aged 49-97 in the Blue Mountains, Australia.
  • Data collected through comprehensive questionnaires and detailed eye examinations, including refraction.
  • Analysis focused on refractive error, age, gender, and education in phakic (natural lens) eyes.

Main Results:

  • Prevalence: 15% myopia, 57% hyperopia, 28% emmetropia.
  • Hyperopia increased with age (36% in <60 years to 71% in ≥80 years), while myopia decreased (21% in <60 years to 10% in ≥80 years).
  • Women were slightly more hyperopic than men. Spherical error, cylinder power, and anisometropia increased with age. Higher education correlated with myopia in men.

Conclusions:

  • This study provides detailed refractive status data for an older population.
  • Findings confirm known trends in refractive error progression with age.
  • An apparent higher prevalence of myopia was observed among younger members of this community, warranting further investigation.
