PROBLEM TO BE SOLVED: To provide an instrument which measures visual field visual perception function based on a reaction time for visual stimulation having a threshold and constant strength and which has means such as in the present invention.SOLUTION: An instrument for measuring visual field visual perception function is characterized in that it includes: a measuring screen forming means; a fixation target display means; a visual target display position specifying means; a visual target display means; a response detection means; a reaction time measuring means for measuring a time from a point of time in which a visual target is displayed by the visual target display means until a point of time in which a response of a subject is detected by the response detection means, as information for suggesting the visual field visual perception function of the subject in the visual target display position; a pair storage means for visual target display position/response time; and a means for forming information suggesting visual field visual perception function at visual target display position. |
