Abstract Objective: To study the changes of accommodative parameters in myopic children during their myopia progression and analyze their roles in myopia progression. Methods: Totally 21 myopic children with mean age of (11.1±1.5) years old were enrolled in this study. Distance accommodative facility and dynamic accommodative stimulus-response curve (ASRC) of right eyes were measured upon enrollment and at 2-year follow-up. Results: Myopia of 21 children significantly progressed (-1.55±0.58) D in 2 years (t=12.24, P<0.01). There were no statistical differences in distance accommodative facility and ASRC related parameters between baseline and 2-year visit (all P>0.05). Accommodative lag was statistically significant only when accommodative stimulus was 4 D (t=-2.018, P=0.048) and there were no statistical differences under other accommodation stimuli (all P>0.05). Multilinear regression analysis found myopia progression was only positively correlated with age (R2=0.186, P=0.029), but not related to accommodative parameters at baseline. Conclusion: During myopia progression in children, accommodative function remains relatively stable. Myopia progression is not related to accommodative parameters, but affected by age. The younger the child, the faster myopia progresses.
