  • Patent number: 8724870
    Abstract: An ophthalmic observation apparatus 1 performs an OCT measurement of a fundus Ef to form an OCT image, performs an analytical processing on this OCT image, and outputs examination-results information including the analysis results. The ophthalmic observation apparatus 1 is capable of selectively executing a plurality of operation modes. The ophthalmic observation apparatus 1 preliminarily stores operation mode information 214, in which various operational details are associated with each operation mode. When one operation mode is designated, the ophthalmic observation apparatus 1 refers to the operation mode information 214 to identify the operational details associated with this operation mode, and controls an optical system, an image forming part 220, a three-dimensional image forming part 231, an analytic processor 232, a display 240, and/or a printer 300, etc. based on the identified operational details.

  • Publication number: 20140078466
    Abstract: A control method of an ophthalmic observation apparatus that comprises an analysis means that analyze an image of an eye formed by using OCT, comprising: storing operation mode information in which an operation mode is associated with operational details of at least the analysis means; identifying the operational details associated with the operation mode by referring to the stored operation mode information; and controlling at least the analysis means based on the identified operational details. The analysis means can execute multiple analytic processings including layer-thickness analysis and/or lesion identification analysis. In the operation mode information, the operation mode is associated with at least one of the multiple analytic processings. In the identifying step, the analytic processing that is associated with the operation mode is identified by referring to the operation mode information. In the controlling step, the identified analytic processing is executed by controlling the analysis means.

  • Patent number: 5903334
    Abstract: An ophthalmologic apparatus comprises a measuring instrument (1) for measuring a subject's eye and an ophthalmologic-data forming instrument (2) for forming ophthalmologic data which is obtained by adding kind data showing the kind of the measuring instrument (1) to measurement data measured by the measuring instrument (1). The ophthalmologic-data forming instrument (2) comprises a memory (2c) for storing the measurement data, a memory (2b) for storing the kind data, and a control unit (2a) for forming and outputting the ophthalmologic data from the data stored in the memories (2b, 2c).

  • Patent number: 5717481
    Abstract: An apparatus for measuring a visual field of a patient, especially characteristics of X ganglion cells, displays a series of targets to a patient. A ramp stimulus is used to measure characteristics of X ganglion cells. A target size setting device sets targets of various sizes. A stimulus intensity changing device changes the intensity of the stimulus in accordance with the size set by the target size setting device. A response device measures the response from the patient, that is, whether the patient senses the target. A memory stores the intensity of stimulus and target size corresponding to the patient's responses.
