Abstract: A system is provided for measuring the color visual fields of a patient's eyes, and includes a viewing area for the patient to direct one of their eyes toward. The viewing area also has a viewing area perimeter, and the viewing area is divided into four substantially equal quadrants. The system further includes a fixation structure, which is located substantially at a central portion of the viewing area. Generally, the purpose of the fixation structure is to hold the attention of the patient. There are also a plurality of predetermined and substantially linear paths included in the system. The paths extend in directions radially outward from the fixation structure toward the viewing area perimeter. The plurality of predetermined paths are spaced apart by substantially equal angles of separation. Also, each quadrant of the viewing area includes at least two predetermined paths therein. A stimuli target is also provided to continuously and automatically move along the predetermined paths.
