Zusammenfassung:PROBLEM TO BE SOLVED: To reduce a load on a subject, in an ophthalmic photographing apparatus photographing an eye to be examined.SOLUTION: An ophthalmic photographing apparatus includes: an illumination optical system emitting illumination light to an eye to be examined; an imaging optical system having an imaging element that receives a reflected light flux from the eye, and having an imaging optical axis inclined to the optical axis of the illumination optical system; and a first optical element for reducing an incidence angle of principal rays of the reflected light flux to an imaging face of the imaging element. Preferably, the ophthalmic photographing apparatus includes an aberration correction member for correcting an aberration generated by the first optical element. Preferably, the illumination optical system and the imaging optical system are provided so as to photograph an anterior ocular segment cross sectional image, and include a drive means for photographing the anterior ocular segment cross sectional image in a plurality of positions.
