However, prevalence dipped to 14% in children 1 to &lt;2 years of age.

However, the prevalence of high astigmatism in Tohono O'odham children increases by age 2 to &lt;3 years to a level near that seen in infancy and remains at that level until at least age 8 years. Longitudinal data are needed to determine whether the increase in high astigmatism after infancy occurs in infants who had astigmatism as infants or is due to the development of high astigmatism in children who did not show astigmatism during infancy.<\/jats:p>\n
