Summary
Refractive errors are common in Jordanian adults, with myopia affecting over half the population. Axial length is the primary ocular correlate of refractive error in this demographic.
Area of Science:
- Ophthalmology
- Optometry
- Public Health
Background:
- Refractive errors represent a significant global health concern.
- Understanding the prevalence and ocular correlates of refractive errors is crucial for targeted interventions.
Purpose of the Study:
- To determine the prevalence of refractive errors in Jordanian adults of working age.
- To investigate the ocular biometric factors associated with refractive error in this population.
Main Methods:
- A cross-sectional study involving 1093 Jordanian adults (aged 17-40).
- Refractive error assessed using autorefraction.
- Ocular biometry measured via A-scan ultrasonography and autokeratometry.
Main Results:
- Prevalence of myopia was 53.71% and hyperopia was 5.67%.
- Emmetropia (40.62%) peaked between plano and 1 D of myopia.
- Axial length (AL) showed the strongest correlation with spherical equivalent refraction.
Conclusions:
- High prevalence of refractive errors, particularly myopia, in Jordanian working-age adults.
- Axial length is a key determinant of refractive error in this population.
- Establishes a foundational dataset for Middle Eastern refractive error research.
