Summary
This summary is machine-generated.In children aged 3-12, older age correlates with longer axial length (AL) and thinner lenses (LT), with lens thickness significantly impacting refractive power more in younger children. Axial length and anterior chamber depth also increase with age.
Area Of Science
- Ophthalmology
- Pediatric Optometry
- Refractive Error Research
Background
- Understanding ocular parameter changes is crucial for monitoring refractive status in children.
- Age-related variations in axial length, lens thickness, and anterior chamber depth influence refractive development.
Purpose Of The Study
- To analyze ocular parameters and refractive status in children aged 3-12 years.
- To investigate age-related differences in ocular parameters within specific refractive error groups.
- To determine the impact of age on refractive progression.
Main Methods
- Collected demographic data, cycloplegic refraction, and ocular parameters from 1504 children's right eyes.
- Analyzed changes in ocular parameters across different age groups.
- Employed multiple linear regression to assess the relationship between age, ocular parameters, and refractive power.
Main Results
- Lens thickness (LT) decreased with age, while axial length (AL) and anterior chamber depth (ACD) increased.
- Age was associated with AL and LT in high hyperopia; AL, LT, and corneal astigmatism in low myopia.
- Lens thickness showed the highest regression coefficient (β=0.41) for refractive power, with a greater effect in younger children.
Conclusions
- In children with similar refractive status, increasing age is linked to longer AL and thinner LT.
- Lens thickness is the ocular parameter most significantly influenced by age.
- The lens plays a more substantial role in refractive power for younger children compared to older ones.
