Accommodative lag and juvenile-onset myopia progression in children wearing refractive correction

AbstractThe relationship between accommodative lag and annual myopia progression was investigated using linear models in 592 myopic children wearing a full refractive correction in the Collaborative Longitudinal Evaluation of Ethnicity and Refractive Error (CLEERE) Study. The mean (±SD) age and spherical equivalent refractive error at baseline were 10.4±1.8years and −2.13±1.24 D, respectively. The mean annual progression of myopia was −0.45±0.32 D, and the mean accommodative lag (for a 4-D Badal stimulus) was 1.59±0.63 D. Neither lag at the beginning nor at the end of a yearly progression interval was associated with annual myopia progression (all p⩾0.12). These data suggest that foveal hyperopic retinal blur during near viewing may not drive juvenile-onset myopia progression
