Test for (1) AC/A ratio: comparison between patient and control groups; (2) myopic shift in the patient group: comparison between adults and children; (3) myopic shift: comparison between patient and control groups; (4) changes in pupillary diameter in binocular viewing condition: comparison between patient and control groups; (5) pupillary diameter changes during switch from monocular to binocular view condition: comparison between patient and control groups; (6) changes in pupillary diameter in monocular viewing condition: comparison between patient and control groups.
