Dynamic ocular visual monitoring system

A medical device for capturing eye movement in response to a moving target (20) includes a camera (40) for capturing images of the eye while the eye is focused on the moving target (20). A movement system (86) controls the motion of the target (20). One or more communication interfaces (110) communicate with external devices. The external devices may include a computing device (115) or a recording device (90) for recording the image and target position data. Computing device (115) may include computer executable software components for controlling the movement system (86) and analyzing the images captured by the camera (40), including determining the position of the center of the pupil within each image and plotting that position against the corresponding position of the target (20) when the image was captured.
