There is provided a perimeter that allows a reliability evaluation to be performed in a kinetic visual field examination. A stimulus for examination is displayed onto an inner surface of a visual field dome and moved at a constant speed on a meridian toward the center of the dome. A subject responds to the stimulus for examination when he visually recognized the moving stimulus. There is displayed a false-negative stimulus, which is more visible than the stimulus for examination, or a false-positive stimulus, which corresponds to the operating sound of the perimeter without any stimulus display. The visual field examination results are evaluated on the basis of a response made by the subject to the false-negative and the false-positive stimuli. This arrangement allows the reliability of the examination results in a kinetic visual field examination to be satisfactorily evaluated.
