Abstract/OtherAbstract:
Purpose To determine the relationships of puberty and growth spurts with peak spherical equivalent (SE) or axial length (AL) velocity in Singapore school children. Methods In the Singapore Cohort study Of the Risk factors for Myopia of 1779 school children, the longitudinal refractive and pubertal status of 892 boys and 887 girls from ages 6 to 14 years were assessed. Refractive error was determined by cycloplegic autorefraction using the Canon RK-F5, and AL was measured using the A-scan biometry. Results The children were examined annually, and the mean number of visits is 5.7 ± 1.3 visits. Age of PHV occurred earlier in girls than boys (11.0 ± 1.2 years versus 12.0 ± 1.7 years, P < 0.001). Girls with earlier PHV experienced peak AL velocity and peak SE velocity about half a year earlier than those with later puberty (mean age of 10.3 ± 1.6 versus 10.8 ± 1.7 years, P < 0.001; and 10.0 ± 1.5 versus 10.6 ± 1.25 years, P < 0.001, respectively). Similarly, boys who had earlier PHV also achieved peak AL and peak SE velocity earlier than those who experienced later PHV (mean age of 10.4 ± 1.6 versus 11.1 ± 1.8 years, P < 0.001; and 10.1 versus 10.6 years, P= 0.01). Conclusions Boys and girls with earlier PHV, experienced earlier peak SE, AL velocity, and age of myopia onset. Thus, variations in the onset and peak progression of myopia may be associated with height spurts.
