Abstract: An ophthalmologic apparatus includes an fixation projection system, an interference optical system, and a controller. The fixation projection system is configured to project fixation light flux onto a fundus of a subject's eye. The interference optical system includes an optical scanner and is configured to split light from light source into measurement light and reference light, to irradiate the subject' eye with the measurement light deflected by the optical scanner, and to detect interference light between returning light of the measurement light from the subject's eye and the reference light. The controller is configured to perform OCT measurement on a first scan region and a second scan region, which are different from each other in the subject's eye, by controlling the interference optical system in a state where a projected position of the fixation light flux on the fundus is fixed.

Abstract: A variable magnification optical component and an ophthalmic apparatus having a simpler mechanism and requiring a small space are provided. The variable magnification optical component includes an optical path, and a power changer, disposed rotatably with respect to an optical axis of the optical path. The power changer is configured to be removably inserted into the optical path, in which the power changer includes: multiple lenses for varying power and a light beam passage hole configured not to interfere with the lenses. In a first configuration of the variable magnification optical component, the power changer is inclined at a predetermined angle, such that the lenses are retracted outside the optical path, and the optical path passes through the light beam passage hole. In a second configuration of the variable magnification optical component, the power changer is restored and the lenses are positioned on the optical path.

Abstract: An ophthalmic apparatus of an embodiment example applies an OCT scan to an anterior segment and constructs an image from acquired data. Further, the ophthalmic apparatus analyzes the image to detect an artifact along an A-scan direction and moves an OCT optical system based on the artifact. Also, the ophthalmic apparatus analyzes the image to detect a corneal image and judges whether an intersection between the artifact and the corneal image is located within a predetermined area. In addition, the ophthalmic apparatus calculates an image quality evaluation value of the image, and controls the OCT optical system to perform an OCT scan of a predetermined pattern if the intersection is located within the area and the image quality evaluation value is equal to or greater than a predetermined threshold.
