1. An ophthalmologic information processing apparatus, comprising:
an image forming circuit configured to form a tomographic image of a subject's eye based on data acquired using optical coherence tomography, the optical coherence tomography using an optical scanner disposed at a position with a first site of the subject's eye;
an intraocular distance calculator circuit configured to obtain an intraocular distance between predetermined sites of the subject's eye based on the data; and
an image correcting circuit configured to correct the tomographic image formed by the image forming circuit, based on the intraocular distance obtained by the intraocular distance calculator, wherein
the image forming unit is configured to form a plurality of tomographic images corresponding to a plurality of traveling directions of measurement light deflected by the optical scanner, and
the image correcting unit is configured to correct each of the plurality of tomographic images formed by the image forming unit so that a distance between the predetermined sites in each of the tomographic images becomes a constant value based on the intraocular distance, and to generate a corrected image in which the corrected plurality of tomographic images is arranged along directions corresponding to traveling directions of the measurement light.
