    • The ophthalmic photographing apparatus includes an optical scanner for two-dimensionally scanning light and an optical coherence tomography device for obtaining a three-dimensional tomographic image of an examiner's eye. The apparatus also includes an observation optical system for obtaining a front observation image of the eye as a moving image and an observation optical system that obtain a front observation image of the examinee's eye as a moving image. The driving control unit controls the optical coherence tomography device based on a signal from an operation unit. A position on the examinee's eye where the tomographic image is picked up is changeable by using the moving image of the front observation image and the analysis map.
