<P>PROBLEM TO BE SOLVED: To provide a perimeter capable of shortening an examination time and improving accuracy of a measurement result. <P>SOLUTION: This perimeter is provided with a visual target presenting means changing the position and brightness of a stimulus visual target presented in the visual field of a subject's eye, and measures a sensitivity threshold of the retina by obtaining a response by the visual recognition of the subject. This perimeter is provided with an objective information input means inputting functional information of the retina corresponding to respective examination points of the stimulus visual target presented by the visual target presenting means and objectively measured by processing ocular fundus images captured before/after the illumination of a visible stimulus light, and a brightness determining means determining an initial reference brightness of the stimulus visual target presented by the visual target presenting means based on the input information for every examination point. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
