[Early age-specific changes in the accommodation volume].
The nearest and furthest points of clear vision were determined in 475 patients aged 6 to 16 years using an AKT-02 device after the optotype of Landolt's ring for 0.7 vision acuity. The mean values of accommodation volume for each age group were determined. They increase from 9.29 +/- 0.19 diopters at the age of 6 years to 12.25 +/- 0.23 diopters at 13, then gradually reduce to 10.0 +/- 0.19 diopters at 16. The descending slope of the curve coincides with the curve plotted by S.L. Shapovalov, who used the same method for measuring the accommodation volume. The volume of accommodation was 0.75 diopters reduced in myopic children in comparison with those with emmetropia.
