<P>PROBLEM TO BE SOLVED: To enable a sure opthalmologic examination to be conducted by preventing a subject from losing sight of a fixation target. <P>SOLUTION: A fixation target display means for guiding a line of fixation of an eye to be examined detects a moving state of an external fixation light 61 and a change in a line-of-sight guiding direction via the selecting state of a plurality of fixation targets 31 in a constitution having the external fixation light 61 and an internal fixation light having a plurality of the fixation targets 31. When the change in the direction of guiding the line of the sight is detected, display states of the external fixation light and the internal fixation light are switched from normal display states to enhanced states. The enhanced states of the external fixation light and the internal fixation light are automatically reset to the normal display state after a predetermined time is elapsed so as not to impart an influence to constricted pupil state of the eye to be examined. The scope of the enhanced state, that is, conditions of amounts of light, flashing or the like of the external and internal fixation lights can be set as desired. <P>COPYRIGHT: (C)2004,JPO |
