Abstract: An ophthalmological imaging device includes illumination optics having an illumination light source that outputs an illumination light, a scanner that redirects the illumination light toward a portion of an object to be imaged, and an optical image capture device including a camera that receives backscattered light that is scattered from the illumination light by the object and captures first and second images of the backscattered light. The device also includes a control processor that controls the scanner and the optical image capture device to cause the optical image capture device to capture the first and second images of the object. The first and second images are captured by the camera at different times and extracted from different portions of the backscattered light. The device also includes an image processor that generates a stereoscopic image from the first and second images of the object.

Abstract: This ophthalmology device includes an illumination optical system, an imaging optical system, and a control unit. The illumination optical system: generates illumination light using light from a light source; and illuminates a changeable illumination region, at a prescribed site of an eye-under-test, with illumination light having an optical intensity corresponding to the size of the illumination region. The imaging optical system guides return light of the illumination light from the eye-under-test toward a light-receiving surface of an image sensor. The control unit: sets an aperture range so as to overlap an illumination range of the return light on the light-receiving surface corresponding to the illumination region; and controls the image sensor so as to capture the light reception results obtained from a light-receiving element in the set aperture range.

Abstract: According to the present invention, an ophthalmic information processing device includes a search unit, a correction unit, and a display control unit. The search unit searches filter information for correcting an aberration of complex OCT data of an inspected eye so that the quality of the complex OCT data is at a prescribed level. The correction unit corrects the aberration of the complex OCT data on the basis of the filter information searched by the search unit. The display control unit causes a display means to display aberration information for the eye plane of the inspected eye corresponding to the filter information searched by the search unit.

Abstract: This ophthalmic information processing device includes an acquisition unit and a normalization unit. The acquisition unit acquires eye shape data or an intraocular distance of an eye of a subject. The normalization unit normalizes the eye shape data or the intraocular distance on the basis of body data of the subject or the degree of refraction of the eye of the subject.

Abstract: An ophthalmological imaging device according to an embodiment of the present invention performs motion contrast imaging by applying OCT scanning to an eye being inspected, and comprises a data acquisition unit, an image formation unit, and a control unit. The data acquisition unit repeatedly applies A scanning, which is primary scanning in the depth direction, to each of a plurality of scanning points to acquire time-series data corresponding to each of the plurality of scanning points. The image formation unit forms a motion contrast image from a plurality of time-series data acquired by the data acquisition unit. The control unit controls the data acquisition unit such that the intervals of data acquisition of first time-series data corresponding to a first scanning point among the plurality of scanning points are substantially equal to the intervals of data acquisition of second time-series data corresponding to a second scanning point.
