All the high myopes seen during the earlier part of the
year, and those in whom the myopia appeared as if it might
be increasing rapidly, were seen at intervals. One boy was
excluded from school on this account.
The numbers of boys and girls who are found to be
myopic are about equal at all ages. The average amount of
myopia found was about constant up to 12 years of age, when
it rose slightly. At 13 the average amount was less because
every child of that age in the schools had had the vision
tested in the routine medical examination, and so a larger
number with small errors were detected, and included in the
total numbers. The average amount of myopia under
scopolamine was 2723 and 2-462 diopters in the right and
left eyes respectively.
