Its object is to provide a system and a method which can cause a monkey to effect accurate visual field determination like a human subject. To achieve the object, according to the invention, there is provided a system for determining visual field of a monkey, comprising: a head fixing unit (A) for fixing a chair (1) to be seated by the monkey and the monkey's head; an eye target display unit (B) for displaying a gazing point (2) at which the monkey is caused to fix its eye and displaying also an eye target (3) at a predetermined position within the monkey's visual field with a predetermined brightness; a gazing monitor unit (C) for monitoring the direction of the monkey's gazing; and a response lever (4) by which the monkey shows that it has recognized the eye target; wherein the head fixing unit (A) includes an attachment member (5) fixable to the top of the monkey's head, a support member (6) connectable to the attachment member (5), and a base member (7) for fixing the support member (6).
