<P>PROBLEM TO BE SOLVED: To provide an ophthalmological photographic apparatus which permits tomograms (light cutting faces) of an eye to be examined to be freely set from the front image of the eye and the conditions of tissue and a disease to be confirmed more detailedly. <P>SOLUTION: The ophthalmological photographic apparatus includes an interference optical system including: a light source emitting light of a low coherence length; a scanning means for scanning the measurement light emitted from the light source on a prescribed region of the eye; and a light-receiving element receiving interference light obtained by synthesizing the reference light generated by light emitted from the light source and the reflected light of the measurement light cast on the prescribed region of the eye, and obtains tomograms in the prescribed region of the eye on the basis of a light reception signal of the light-receiving element. The apparatus includes: a stream specification means for specifying light cutting lines as streams of the nerve fibers of the fundus of the eye; and a tomogram acquisition means for acquiring tomograms corresponding to the light cutting lines specified by the stream specification means. <P>COPYRIGHT: (C)2010,JPO&INPIT |
