Background

Progressive axial elongation is a key structural indicator of myopia progression.

Purpose

This study examined the association between stable habitual spectacle-corrected distance visual-acuity profiles and annualized axial length growth.

Methods

This retrospective real-world cohort study used the Chengdu school-based myopia screening database.

n = 4152 children

Results

eyes stayed corrected grew about this much slower per year than under-corrected eyes

MD -0.14 (95% CI -0.17 to -0.11)

CI excludes the null - significant

More results

The final cohort included 4152 children: 391 ACG, 551 UCG, and 3210 UMG.

No statistically significant ΔAL difference was detected between the UCG and UMG ( p = 0.412).

Sensitivity analyses yielded consistent findings.

Conclusion · 1 of 2

Stable habitual spectacle-corrected distance visual-acuity profiles were associated with annualized axial length growth.

Conclusion · 2 of 2

Achieved visual acuity under habitual spectacle-wearing conditions may provide information beyond spectacle-wearing status alone; however, these observational findings do not establish equivalence, predictive utility, or causality.
