Myopia progression analysis device, myopia progression analysis system, myopia progression analysis method, and myopia progression analysis program

A myopia progression analysis system for analyzing progression of myopia of a subject, the myopia progression analysis system comprising:

• a memory storing computer program instructions;
• at least one processor configured to execute the computer program instructions, the computer program instructions configured to cause the at least one processor to perform operations of:
• measuring an eye axial length of an eye of the subject;
• acquiring the eye axial length;
• acquiring a numerical value related to a physical characteristic of the subject other than the eye axial length as a reference value;
• calculating a relative eye axial length through relativization of the eye axial length using the reference value;
• acquiring population information which is a set of information about relative eye axial lengths of a plurality of comparison targets to be compared with the subject;
• and
• comparing the relative eye axial length of the subject with the relative eye axial lengths of the plurality of comparison targets included in the population information to calculate relative position information indicating a relative position of the relative eye axial length of the subject in the set of comparison targets,
• wherein the physical characteristic of the subject used as the reference value is a physical characteristic related to a body part of the subject, and is any one of an eye socket size, height of the subject, or head size of the subject.
