    Abstract: A slit lamp microscope of some embodiment examples includes an illumination system, first photographing system, first movement mechanism, and controller. The illumination system includes a slit forming unit that forms a slit for generating slit light and projects the slit light onto an anterior segment of a subject's eye from a first direction. The first photographing system photographs the anterior segment onto which the slit light is being projected, from a second direction different from the first direction. The first movement mechanism moves a movable portion that includes at least the slit forming unit. The controller performs a first control for the first movement mechanism to move the movable portion and a second control for the first photographing system to photograph the anterior segment a plurality of times in parallel with each other.

    Abstract: The object of the present invention is to develop an ophthalmologic microscope of a new method that increases the degree of freedom in the optical design in the Galilean ophthalmologic microscope provided with an OCT optical system. The present invention provides an ophthalmologic microscope, wherein an observation optical system, an objective lens, and an OCT optical system are placed in such a way that the optical axis of the OCT optical system does not penetrate through objective lens, and the optical axis of the observation optical system and the optical axis of the OCT optical system are non-coaxial, and wherein the ophthalmologic microscope further comprises a SLO optical system that scans a light ray which is a visible ray, a near infrared ray, or an infrared ray and guides the light to the subject's eye so as to become substantially coaxial with the optical axis of the OCT optical system.

    Abstract: A full-range imaging method doubles imaging range of conventional techniques by removing mirror images of an imaged object that limit conventional images to a “half-range” and that are caused in part by the loss of phase information in a detected signal. Phase information of the detected signal is reconstructed with an averaging technique based on a modulated phase induced in the detected signal during scanning.

    Abstract: An ophthalmic observation apparatus according to an embodiment example includes a moving image generating unit, an analyzing processor, a target position determining processor, and a display controller. The moving image generating unit is configured to generate a moving image by photographing the subject's eye. The analyzing processor is configured to analyze a still image included in the moving image to detect an image of a predetermined site of the subject's eye. The target position determining processor is configured to determine a target position for a predetermined treatment based at least on the image of the predetermined site detected by the analyzing processor. The display controller is configured to display, on a display device, the moving image and target position information that represents the target position.
