A perimeter has fixation state judging means for individually judging a fixation state of an examinee in connection with each presented stimulus, and the fixation state judging means individually judges the fixation state whenever the stimulus is presented. Even if defective fixation is judged, retest is conducted on only a point where the stimulus was presented, which was judged to be defective fixation. Then, examiner's burden and examinee's burden can be lightened, the test time can be made shorter and test efficiency can be improved in comparison with a case where the whole test is retried from the first as a conventional way.
