A perimeter for inspecting a visual field of an examinee in such a state the examinee fixates a fixation point on a presenting portion of a stimulus presenter, comprising: when a region on which a perimetry is expected is referred to as "the inspection region", an upper limit time for conducting the perimetry is referred to as "the upper limit time", a region in which one or more visual stimuli are presented to the examinee is referred to as "the stimulus presentation region", and a spot to which the stimuli are presented in the stimulus presentation region is referred to as "the stimulus presentation spot"; a region designator that is configured to display an image that shows a past perimetry result ("the perimetry result image" hereinafter) or a fundus image (both images are collectively referred to as "the designation images" hereinafter) on a monitor, and to designate a part of the designation image as the inspection region (B,B1∼B3) on the designation image displayed on the monitor through an input portion; a region determinator that is configured to determine the stimulus presentation region (E1∼E3) including the designated inspection region(B,B1∼B3) in the designation image based upon the designated inspection region (B,B1∼B3); an upper limit time setter that is configured to set the upper limit time (Tmax) in the perimeter; a position determinator that is configured to determine a position of each stimulus presentation spot (P 1,... P 1 '....) in the determined stimulus presentation region (E1∼E3) that enables completing the perimetry of the perimeter under a condition lower than the upper limit time (Tmax); the stimulus presenter having the presenting portion for presenting the stimuli thereon, that presents the one or more visual stimuli in order with a predetermined brightness to each corresponding position on the presenting portion determined by the position determiner; an operation portion to be operated by the examinee when the examinee perceives the presented one or more visual stimuli; and a result judger that is configured to judge the inspection result based upon signals from the stimulus presenter and the operation portion. when a region on which a perimetry is expected is referred to as "the inspection region", an upper limit time for conducting the perimetry is referred to as "the upper limit time", a region in which one or more visual stimuli are presented to the examinee is referred to as "the stimulus presentation region", and a spot to which the stimuli are presented in the stimulus presentation region is referred to as "the stimulus presentation spot"; a region designator that is configured to display an image that shows a past perimetry result ("the perimetry result image" hereinafter) or a fundus image (both images are collectively referred to as "the designation images" hereinafter) on a monitor, and to designate a part of the designation image as the inspection region (B,B1∼B3) on the designation image displayed on the monitor through an input portion; a region determinator that is configured to determine the stimulus presentation region (E1∼E3) including the designated inspection region(B,B1∼B3) in the designation image based upon the designated inspection region (B,B1∼B3); an upper limit time setter that is configured to set the upper limit time (Tmax) in the perimeter; a position determinator that is configured to determine a position of each stimulus presentation spot (P 1,...
