摘要:
An ophthalmologic imaging device can shoot a diagnostically important area from the macula to the optic papilla in a wide angle of view without flares without trouble by a single imaging operation. An optical illumination system (25) includes a cornea aperture (34), an iris aperture (35), and a lens aperture (36) conjugate to the cornea (C) of the subject eye (E), the iris of the subject eye (E), and the posterior surface of the lens, respectively, and an split mark projection system (41) for focusing on the fundus (Ef) of the subject eye (E). A light source (37) is controlled by a controller to emit light for being able to obtain at least two consecutive fundus images. An inner aperture image (q3) corresponding to the lens aperture (36) is projected on the posterior surface of the lens. The controller (23) controls the lens aperture (36) so that for obtaining a second fundus image, the inner aperture image (q3) is projected at a position shifted relative to the optical axis of an optical observatory or imaging system (27, 26) from a position at which the aperture image is projected for obtaining a first fundus image.
