An optical coherence tomographic device of polarization-sensitive type may include: an image capturing unit configured to capture a tomographic image of a subject eye, and a display unit configured to display the tomographic image captured by the image capturing unit. The tomographic image may include at least two images selected from a group consisting of: an image showing a tissue in the subject eye by scattering intensity, an image showing a melanin distribution in the subject eye, an image showing a fiber density in the subject eye, an image showing a fiber direction in the subject eye, and an image showing a blood flow in the subject eye. The display unit may be configured to display the at least two images at a same position and on a same cross section such that the at least two images are superimposed on each other.

Optical coherence tomographic device and non-transitory computer-readable recording medium storing computer-readable instructions for optical coherence tomographic device

A tomographic image processing device that includes an input unit configured to input a tomographic image of a subject eye; a processor; and a memory storing computer-readable instructions therein. The computer-readable instructions, when executed by the processor, may cause the processor to execute: acquiring a tomographic image of a normal eye; acquiring a tomographic image of an eye having an abnormal portion; extracting a feature amount of the abnormal portion by using machine learning from the tomographic image of the normal eye and the tomographic image of the eye having the abnormal portion; acquiring a tomographic image of the subject eye inputted to the input unit; and determining whether the tomographic image of the subject eye includes an abnormal portion based on the feature amount.

Tomographic image processing device, ophthalmic device comprising the same and non-transitory computer-readable recording medium storing computer-readable instructions for tomographic image processing device

An ophthalmic device capable of obtaining B-scan graphical images at high speed while eliminating positional displacement due to movement of a subject eye. The device includes: anterior eye image obtaining means configured to obtain an image of an anterior eye of a subject eye; eye fundus image obtaining means configured to obtain an image of an eye fundus of the subject eye; and control means configured to detect a moving distance of the subject eye in the anterior eye image using means configured to calculate correlation between a moving distance of the subject eye in the anterior eye image and a moving distance in the eye fundus image, and to control a position for imaging of the eye fundus image based on the detected moving distance of the subject eye and the calculated correlation.
