Truckenbrod C, Meigen C, Brandt M, et al. - In this longitudinal and cross‐sectional LIFE Child Study, experts aspired to explore whether percentile curves of axial length (AL) can be used as a predictive measure of myopia. Children’s non‐cycloplegic refraction data were obtained using the Zeiss i.Profiler plus while AL was measured using the Haag‐Streit Lenstar. Data from 4,511 visits of 1,965 candidates (1021 boys and 944 girls) between 3 and 18 years of age have been analyzed. The LIFE Child Study data offers European AL data. When the baseline ALs are compared as percentiles, AL has comparable growth rates in both Germany and China. As a result, AL percentile curves can be used to predict the likelihood of developing as well as the progression of myopia.
