Claim One:
1. A method for testing eye muscle function of all six muscles involved in ocular movements to determine a reduction in brain function for an operator, said method comprising: providing a display, a user input device, and an associated computer; continuously displaying a movable blob around said display, for viewing by an operator, the blob being spatially confined within an extent when viewed by the operator such that the operator's gaze may vary within the spatial confines of the extent of the blob without constituting fixation error, the extent of the blob termed a fixation zone; moving said blob on said display, under control of said computer, as said operator attempts to maintain gaze within said continuously displayed fixation zone, the moving performed in such a manner that all six eye muscles regulating eye movement are involved as said operator attempts to maintain gaze; detecting, with said user input device, said operator's attempted gaze within or outside said continuously displayed fixation zone; over a total time, determining a cumulative amount of time the gaze of the operator is within the fixation zone, and determining a cumulative amount of time the gaze of the operator is outside the fixation zone; analyzing, with said computer, said operator's performance at following said continuously displayed fixation zone, said operator's performance including an ability of the operator to maintain gaze within the fixation zone constituting no fixation error versus outside the fixation zone constituting fixation error; comparing said performance with a previously established baseline performance; and providing a result of said performance comparing.
