Abstract: An OCT apparatus includes an OCT optical system guiding measurement light to a region including a central portion and a peripheral portion of a fundus, and an image processor processing a spectral interference signal output from the OCT optical system to acquire OCT data of an examinee's eye. The OCT optical system includes a first reference optical path having a path length for obtaining OCT data including the central portion and a second reference optical path having a path length for obtaining OCT data including the peripheral portion. The image processor obtains OCT data including the central portion based on an interference signal between measurement light guided to the central portion and reference light from the first reference optical path, and obtains OCT data including the peripheral portion based on an interference signal between measurement light guided to the peripheral portion and reference light from the second reference optical path.

Abstract: A dyeing device dyes a resin body by vaporizing and depositing a sublimation dye adhered to a dyeing base to a resin body and fixing the dye to the resin body. The dyeing device lowers the pressure inside a closed chamber that closes the periphery of the resin body by a pump. In the state where the adhesion surface of the dyeing base to which the dye is adhered faces the resin body without contact, by heating the dye adhered to the dyeing base inside the closed chamber of which the pressure is lowered, the dye is sublimated, vaporized, and deposited on the resin body. The pressure inside the closed chamber is raised higher than the pressure at the vaporizing and depositing time. By irradiating the resin body on which the dye is vaporized and deposited with electromagnetic wave, the resin body is heated and the dye is and fixed.

Abstract: A dyeing method in which a transparent resin body having a surface applied with a dye is heated to fix the dye to the transparent resin body comprises a heating step of irradiating a laser beam having a wavelength less likely to be absorbed by the dye toward the transparent resin body applied with the dye on the surface while relatively scanning the laser beam with respect to the transparent resin body to heat a to-be-dyed region of the transparent resin body to fix the dye, wherein the laser beam is irradiation to heat by changing a laser beam irradiating condition with respect to a portion of the transparent resin body to be heated so that a heating temperature on the transparent resin body by irradiation of the laser beam is substantially equal throughout an entire area of the to-be-dyed region.

Abstract: An ophthalmic surgical microscope includes an observation optical system configured to guide observation luminous fluxes for a right eye and a left eye from an observation object to an imaging device, an actuator configured to move a position of the observation optical system in at least a direction intersecting with the observation luminous fluxes, a processor, and a memory storing computer-readable instructions. The computer readable instructions, when executed by the processor, cause the ophthalmic surgical microscope to cause a stereoscopic image display to display an observation image to be observed with a right eye of a user and an observation image to be observed with a left eye of the user, detect a position of the observation object with respect to the observation optical system, and correct a deviation in a relative position of the observation optical system with respect to the observation object.
