Abstract: Disclosed is a myopia progression analysis device including: an eye axial length acquisition section 111 that acquires an eye axial length of an eye of a subject; a reference value acquisition section 112 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 113 that calculates a relative eye axial length through relativization of the eye axial length acquired by the eye axial length acquisition section 111 using the reference value acquired by the reference value acquisition section 112; a population information acquisition section 114 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 115 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.
