Outline of Final Research Achievements

We devised a new type of chromatic pupil perimeter for objective visual field measurement. This system consists of an LED type of liquid crystal display for generating chromatic stimulus and an infrared CCD camera with a macro lens for recording pupil responses.
With changing of the kind of stimulus, such as color, it may be possible for pupil perimetry to detect visual field disturbances more sharply than conventional method. We supposed that a chromatic pupil perimeter can be used in clinical applications for evaluating an objective visual field easily.
