摘要:
PROBLEM TO BE SOLVED: To provide an ophthalmic perimeter which achieves reliable evaluation in dynamic examination of a visual field.SOLUTION: An test stimulus 40 is projected and presented on the inner face of a visual field dome and moved on the longitude θ toward the center of the dome at a constant speed. A subject responds to the test stimulus when the stimulus moves from P1 to P2. A false-negative stimulus 41 with visibility higher than that of the test stimulus or the test stimulus is not presented but a false-positive stimulus 42 including moving sound of the stimulus is presented, and a result of the visual field examination is evaluated based on the response of the subject for the presented false-negative stimulus and the false-positive stimulus. Since, in such a configuration, the false-negative stimulus and the false-positive stimulus can be presented by a simple configuration, the reliability of the examination result in the dynamic visual field examination can be excellently evaluated.
