Functional Classes of Eye Movements Class of Eye Movement Main Function Gaze-Holding Visual Fixation Holds the image of a stationary object on the fovea Vestibulo-ocular reflex Holds images of the seen world steady on the retina during brief head rotations Optokinetic Holds images of the seen world steady on the retina during sustained and low frequency head rotations Gaze-Shifting Smooth Pursuit Holds the image of a moving target close to the fovea Nystagmus quick phases Resets the eyes during prolonged rotation and directs gaze towards the oncoming visual scene Saccades Directs images of eccentrically located objects of interest onto the fovea Vergence Moves the eyes in opposite directions so that images of a single object are place simultaneously on both foveas
