<P>PROBLEM TO BE SOLVED: To provide a perimeter with which time required for measurement in performing dynamic visual field measurement can be shortened and a highly accurate result can be obtained. <P>SOLUTION: The perimeter for projecting an examination visual target to the eye ground of an eye to be examined and measuring a visual field by the visual recognition response of a subject comprises: an observation optical system for observing the eye ground of the eye to be examined; a display means for displaying the eye ground image of the eye to be examined observed in the observation optical system; a position decision means for deciding the positions of the macula or central fovea and an optic disk in the eye ground image displayed by the display means; a fiber bundle travel decision means for deciding the travel of a nerve fiber bundle in the eye ground image from the positional relation of the macula or central fovea and the optic disk decided by the position decision means; a moving means for moving the examination visual target projected on the eye ground of the eye to be examined along the travel of the nerve fiber bundle obtained by the fiber bundle travel decision means; and a response means for performing visual recognition responses for the examination visual target moved by the moving means. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
