<P>PROBLEM TO BE SOLVED: To provide an ophthalmic measurement apparatus capable of accurately obtaining an actual distance on an eye fundus. <P>SOLUTION: The eye fundus is photographed by a photographing optical system in which a mask determining the photographing range of the eye fundus is arranged at an eye fundus conjugate position, and it is displayed on a display part 50. Two points P1 and P2 are specified on a displayed fundus image, the size of the mask on the eye fundus calculated in accordance with the diopter of an eye to be examined and an ocular axial length is read, and from a coordinate distance d1 on the display image of the mask and a coordinate distance d2 on the display image between the two specified points, the actual distance of d2 on the eye fundus is computed. In such constitution, since the actual distance on the eye fundus is obtained on the basis of the information of the eye to be examined affecting a photographing magnification and the information of the photographing optical system, the actual distance on the eye fundus can be accurately obtained. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
