Ophthalmic image processing device, OCT device, and non-transitory computer-readable storage medium

An OCT device that captures an ophthalmic image of a tissue of a subject eye by processing an OCT signal derived from reference light and reflected light of measurement light with which the tissue is irradiated, comprising:

• a controller configured to:
• acquire a probability distribution for identifying a tissue in the ophthalmic image by inputting the captured ophthalmic image into a mathematical model trained with using a machine learning algorithm;
• and
• acquire a degree of divergence of the acquired probability distribution with respect to the probability distribution acquired in a case where the tissue is accurately identified, as structural information indicating a degree of abnormality in a structure of the tissue.

A non-transitory computer-readable storage medium storing an ophthalmic image processing program executed by an ophthalmic image processing device that processes an ophthalmic image which is an image of a tissue of a subject eye, the program being executed by a controller of the ophthalmic image processing device to cause the ophthalmic image processing device to execute:

• an image acquisition step of acquiring an ophthalmic image captured by an ophthalmic image capturing device;
• a probability distribution acquisition step of acquiring a probability distribution for identifying a tissue in the ophthalmic image by inputting the ophthalmic image into a mathematical model trained with using a machine learning algorithm;
• and
• a structural information acquisition step of acquiring a degree of divergence of the acquired probability distribution with respect to the probability distribution acquired in a case where the tissue is accurately identified, as structural information indicating a degree of abnormality in a structure of the tissue.
