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: A medical diagnostic apparatus includes a receiver circuit that receives three-dimensional volumetric data of a subject's eye, and a processor configured to separate portions of the three-dimensional volumetric data into separate segments, perform processing differently on each of the separate segments, and combine the separately processed segments to produce an enhanced three-dimensional volumetric data set. The processor is further configured to generate at least one diagnostic metric from the enhanced three-dimensional volumetric data set, and the processor is further configured to evaluate a pathological condition based on the at least one diagnostic metric. Related methods and computer readable media are also disclosed.

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: An illumination system of the ophthalmological device of an exemplary embodiment projects illumination light that has been outputted from a light source onto an anterior eye part of an examined eye. An interference photography system photographs an interference pattern that is formed on the cornea by the illumination light. An anterior eye part photography system photographs the anterior eye part onto which the illumination light is being projected. A first optical path coupling element couples the optical path of the interference photography system and the optical path of the anterior eye part photography system. A control part aligns an observation interference image that is at least a portion of an interference image that has been acquired by the interference photography system and an anterior eye part image that has been acquired by the anterior eye part photography system and makes a display device display the aligned images. The control part also makes the display device display observation location information that indicates the location of the observation interference image on the anterior eye part image.
