Anterior segment three-dimensional image processing apparatus, and anterior segment three-dimensional image processing method

A computer-readable recording medium that stores a program for causing a computer to function as:

• a first SS position specifying unit that accepts identification of at least three SS positions indicating a spatial coordinate position of a scleral spur of a subject's eye, using at least two representative images from among a plurality of two-dimensional tomographic images constituting an anterior segment three-dimensional image of the subject's eye;
• a true circle calculating unit that calculates a reference true circle passing through the at least three SS positions of the SS positions identified by the first SS position specifying unit in the anterior segment three-dimensional image;
• and
• a second SS position specifying unit that identifies the SS positions in non-representative images other than the representative images from among the plurality of two-dimensional tomographic images, based on the reference true circle calculated by the true circle calculating unit.

An anterior segment three-dimensional image processing method for processing an anterior segment three-dimensional image of a subject's eye by means of an optical coherence tomography device, the method comprising:

• a determination step in which whether or not there is a displacement of a spatial coordinate position is determined based on two-dimensional tomographic images that constitute the anterior segment three-dimensional image;
• a first SS position specifying step in which identification of at least three SS positions indicating a spatial coordinate position of a scleral spur of the subject's eye is accepted using at least two representative images from among the two-dimensional tomographic images;
• a true circle calculating step in which a reference true circle is calculated that passes through the at least three SS positions identified in the first SS position specifying step in the anterior segment three-dimensional image;
• and
• a second SS position specifying step in which the SS positions in non-representative images other than the representative images from among the two-dimensional tomographic images of respective slice planes constituting the anterior segment three-dimensional image, are identified based on the reference true circle calculated in the true circle calculating step.
