PROBLEM TO BE SOLVED: To provide a method free from the extension of test time caused by the interruption of a test by eliminating defects in a prior art. SOLUTION: The visual field functions of a human eye is examined fixing the eye to a determined observation part 10 in the direction of an observation axis 9. A means containing a light source 13 acts to generate a stimulus gradually by time in a selectable position in a range of fixed marks 32, F positioned on the observation axis 9. The perimeter 1 provided with a computer 5 and a camera 34 for observing the eye 6 catches the position of the eye by the camera 34 and automatically examines the discrepancy of the position of the eye from the demarcated fixed marks. A correction is automatically made on the basis of the discrepancy examined in the perimeter 1, and the arrangement of a testing position is corrected on the basis of the examined discrepancy.
METHOD FOR EXAMINING VISUAL FUNCTION CAPACITY OF HUMAN EYE, AND PERIMETER FOR CARRYING OUT THE METHOD
