PROBLEM TO BE SOLVED: To provide an ophthalmic photographing apparatus to perform favorable fundus measurement using a fundus tomographic image in photographing the fundus of an examinee's eye.SOLUTION: The ophthalmic photographing apparatus including: an interference optical system for dividing a light flux from a light source into measurement light and reference light, directing measurement light to the fundus of a subject and reference light to a reference optical system, and photo-receiving interference light obtained by synthesis of the measurement light flux reflected by the fundus and the reference light flux by a first photodetector; an optical scanner changing advancement direction of the measurement light flux to scan the measurement light flux on the fundus; a driving unit moving an optical member in the optical axis direction to change an optical path length; a calculation control unit controlling the driving unit and controlling the motion of the optical scanner to make the measurement light flux scan in an photographing angle on the fundus to obtain a tomographic image of the fundus based on receiving light signals outputted from the photodetector. The calculation control unit converts a photographing range of the tomographic image into an actual distance based on optical member positional information and photographing angle information and photographing angle information of the tomographic image. |
