11 Claims

1. An ophthalmologic information analysis apparatus for analyzing OCT data captured by scanning a subject eye with measurement light by an optical coherence tomography, the apparatus comprising:

a display; and

a central processing unit configured to:

acquire first analysis data obtained by analyzing an analysis region of the subject eye in first OCT data including the analysis region, the analysis region being obtained by scanning the measurement light in a transverse direction in a first scanning range on the subject eye;

acquire second OCT data captured on a day different from that of the first OCT data, the second OCT data including at least the analysis region obtained by scanning the measurement light in the transverse direction in a second scanning range different from the first scanning range on the subject eye;

perform an analysis comprising:

specifying the analysis region corresponding to the first analysis data from the second OCT data; and

acquiring second analysis data obtained by analyzing the analysis region in the second OCT data, regardless of a difference between the first scanning range and the second scanning range; and

control the display to display the first analysis data and the second analysis data in a comparable manner,

wherein the first OCT data is a plurality of pieces of data including data including a first analysis region as the analysis region and data including a second analysis region different from the first analysis region as the analysis region, in which the first scanning ranges are different from each other,

wherein the central processing unit is configured to:

acquire the first analysis data obtained by analyzing the first analysis region and the second analysis region in the acquiring of the first analysis data;

acquire the second OCT data including both the first analysis region and the second analysis region as the analysis region in the acquiring of the second OCT data; and

specify at least one of the first analysis region and the second analysis region corresponding to the first analysis data from the second OCT data, and acquire the second analysis data obtained by analyzing at least one of the first analysis region and the second analysis region in the second OCT data in the performing of the analysis.
