摘要： PROBLEM TO BE SOLVED: To provide an ophthalmologic imaging device capable of unhindered wide angle imaging from the diagnostically important macula region to the optic papilla region with a single imaging maneuver while avoiding the inclusion of flare.SOLUTION: Provided in an optical illumination system (25) are a corneal aperture (34) conjugate to the cornea (C) of the subject eye (E), an iris aperture (35) conjugate to the iris of the subject eye (E), a lens aperture (36) conjugate to the posterior surface of the lens, and an optical split mark projection system (41) for focusing on the fundus (Ef) of the subject eye (E). Light emission of the illuminating light source (37) is controlled by a control unit (23) so that at least two photographic images of the fundus can be acquired consecutively. On the posterior surface of the lens, an internal aperture image (q3') that corresponds to the lens aperture (36) is projected. The control unit (23) controls the lens aperture (36) so that the projection position of the internal aperture image (q3') when acquiring the second photographic image of the fundus is shifted on the optical axis of the optical observation and imaging systems (27, 26) from the projection position of the aperture image when acquiring the first photographic image of the fundus.

摘要： PROBLEM TO BE SOLVED: To provide a fundus observation device which captures surface images and tomographic images of a fundus oculi and prevents a reduction in interference efficiency of the signal light and reference light in optical image measurement. SOLUTION: An arithmetic control device 200 forms the surface image of the fundus oculi Ef from signals of a fundus camera unit 1A. An OCT (optical coherence tomography) unit 150 divides low coherence light L0 into signal light LS and reference light LR and detects interference light LC produced from the signal light LS passing through the fundus oculi Ef and the reference light LR passing through a reference mirror 174. The arithmetic control device 200 forms the tomographic image of the fundus oculi Ef from the detected result. A Dichroic mirror 134 combines the optical path of the signal light LS toward the fundus oculi Ef into the optical path for imaging of the fundus camera unit 1A and separates the optical path of the signal light LS passing through the fundus oculi Ef from the optical path for imaging. An optical fiber 163 has a fiber length to provide the dispersion amount, which is approximately equal to the dispersion amount provided to the signal light LS, to the reference light LR.

The concave lens imaging position changing member 40 is arranged at the second optical path 39 to make it possible to change the imaging point M1 of the fundus oculi by the imaging lens to the imaging point M2 which is the backward position. As a result, the field is made movable laterally, insertible into the optical path and is attachable and detachable to and from the optical path.
