  • Patent number: 12059209
    Abstract: 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.

  • Patent number: 11024416
    Abstract: 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.

  • Publication number: 20180058978
    Abstract: A lensmeter includes a light emission portion, a light reception portion, a storage unit, a display unit and a display control unit. The light emission portion emits light so as to radiate the light onto a lens-to-be-inspected. The light reception portion receives the light transmitted through the lens-to-be-inspected to measure an optical characteristic of the lens-to-be-inspected. The storage unit stores a measured value of the optical characteristic of the lens-to-be-inspected. The display unit displays the measured value of the optical characteristic of the lens-to-be-inspected stored in the storage unit. The display control unit causes the display unit to display a target pattern including at least two different colors, and changes the target pattern in accordance with the measured value stored in the storage unit.

The light emission portion includes a measurement light source configured to emit green light or red light for measurement of refractive power of the lens-to-be-inspected, a first inspection light source configured to emit ultraviolet light, and a second inspection light source configured to emit blue light. The light reception portion is configured to selectively receive lights from the measurement light source, the first inspection light source and the second inspection light source respectively.

  • Patent number: 9818030
    Abstract: 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.
