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 measurement section that measures an eye axial length of an eye of the subject;
• an eye axial length acquisition section that acquires the eye axial length measured by the measurement section;
• a reference value acquisition section that acquires a numerical value related to a physical characteristic of the subject other than the eye axial length as a reference value;
• a relative eye axial length calculator that calculates a relative eye axial length through relativization of the eye axial length acquired by the eye axial length acquisition section using the reference value acquired by the reference value acquisition section;
• a population information acquisition section that acquires 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
• a relative position information calculator that compares the relative eye axial length of the subject calculated by the relative eye axial length calculator 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.

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

• acquiring, by an eye axial length acquisition section, an eye axial length of an eye of the subject;
• acquiring, by a reference value acquisition section, a numerical value related to a physical characteristic of the subject other than the eye axial length as a reference value;
• calculating, by a relative eye axial length calculator, a relative eye axial length through relativization of the eye axial length acquired by the eye axial length acquisition section using the reference value acquired by the reference value acquisition section;
• acquiring, by a population information acquisition section, 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, by a relative position information calculator, the relative eye axial length of the subject calculated by the relative eye axial length calculator 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.
