Fixation or visual fixation is the maintaining of the gaze on a single location. An animal can exhibit visual fixation if it possess a fovea in the anatomy of their eye. The fovea is typically located at the center of the retina and is the point of clearest vision. The species in which fixational eye movement has been verified … See more In 1738, James Jurin made the first known reference to a "trembling of the eye" that was presumably caused by fixational eye movements. Robert Darwin noted in 1786 that the jiggling of color after-effects was presumably the … See more Ocular drift is the fixational eye movement characterized by a smoother, slower, roaming motion of the eye when fixed on an object. The … See more • Rapid eye movement • Microsaccade • Ocular tremor • Saccade See more A microsaccade, also known as a "flick", is a type of saccade. Microsaccades are the largest and fastest of the fixational eye movements. Like saccades in general, microsaccades are usually binocular, and conjugate movements with comparable amplitudes and … See more Ocular microtremors (OMTs) are small, quick, and synchronized oscillations of the eyes occurring at frequencies in a range of 40 to 100 Hz, although they typically occur at around 90 Hz in the average healthy individual.
