摘要： An ophthalmic apparatus includes a tester having a target projecting optical system and a target photographing optical system. with a configuration on an examinee's eye side being non-telecentric, an alignment adjuster that adjusts at least a positional relationship between an examinee's eye and the tester in the direction of a working distance between the examinee's eye and the tester, and a corrector that acquires an actual error from a proper working distance based on association information indicating the association of position information on the positions of first and second target images on an observation image with an error in the working distance with respect to the proper working distance due to the corneal curvature radius of the examinee's eye and the non-telecentricity of the target photographing optical system and the position information on the tester at the current position thereof in the working distance direction, correcting the actual error.

摘要： An OCT device includes an OCT optical system and a controller that also serves as an image processor. The controller acquires the OCT data of the fundus by processing the spectral interference signal output from the OCT optical system. In addition, the controller adjusts the position of the high accuracy region, which is the depth region where relatively high accuracy OCT data is obtained, by controlling the OCT optical system in accordance with the curvature level of the fundus image in the photographing range of the OCT data. This makes it possible to acquire good OCT data regardless of the curvature level of the fundus.

摘要： A processor of a fundus image processing device acquires a fundus image 50 photographed by a fundus image photographing device. The processor acquires blood vessel images 60A and 60B that indicate at least one of an arteriole and a venule in the fundus image 50 by inputting the fundus image 50 into a mathematical model trained by a machine learning algorithm. The processor acquires a blood vessel area that is an area of at least one of the arteriole and the venule in the whole of the blood vessel images 60A and 60B.

摘要： An ultrasonic tonometer, which measures an intraocular pressure of a subject eye using an ultrasonic wave, has an ultrasonic actuator including an ultrasonic element that generates an ultrasonic wave and a sonotrode that propagates the ultrasonic wave generated from the ultrasonic element, and irradiating the subject eye with the ultrasonic wave. The sonotrode includes an uneven portion in which a thickness of the sonotrode varies in a sound axis direction of the ultrasonic wave.
