 (să-käd′, sə-)
A rapid intermittent eye movement, as that which occurs when the eyes fix on one point after another in the visual field.

[French, jerk, jolt, from Middle French, from Old French dialectal saquer, to jerk, pull, variant of Old French sachier, to pull forcefully, turn over, shake up, from sac, sack (perhaps in reference to the shaking of bags of wheat to settle their contents); see sac1.]

Generally, the main purpose of a saccadic eye movement is to bring a particular part of the visual scene onto the fovea, allowing visual attention to be directed to this area.
Saccadic movements are the fast and intermittent jumps of the eye's position when fixing onto a foveal object.
The whole image projected on the retina (the whole retinal image) not only moves rapidly during saccadic eye movements but also jitters even during steady gaze due to the nature of fixational eye movements.
The purpose of this study was to investigate the effect of visual skills training on saccadic eye movements and performance level of vault for junior gymnasts.
Twenty-eight patients with persistent unilateral vestibular dysfunction were allocated into two groups; in one group patients tried to practice saccadic oculomotor exercises, and VES was administered to the second group through surface electrodes on the opposite impaired side and patients were told to walk during the electrical stimulation.
Its principle objective was to evaluate the ability of GR3027 to antagonize allopregnanolone-induced activation of GABAA as determined by its pharmacodynamic effects on two GABAA-modulated CNS functions, Saccadic Eye Velocity (SEV) and self-rated sedation using a Visual Analogue Scale (VAS).

Stimulus intensity modifies saccadic reaction time and visual response latency in the superior colliculus.
Results: (1) In the fixation task, compared to healthy controls, patients with depressive disorder showed more fixations, shorter fixation durations, more saccades and longer saccadic lengths; (2) In the saccade task, patients with depressive disorder showed longer anti-saccade latencies and smaller anti-saccade peak velocities; (3) In the free-view task, patients with depressive disorder showed fewer saccades and longer mean fixation durations; (4) Correlation analysis showed that there was a negative correlation between the pro-saccade amplitude and anxiety symptoms, and a positive correlation between the anti-saccade latency and anxiety symptoms.
Interestingly, hyperreflexia was found in 7/16 patients (44%), and slowing of saccadic eye movements was seen in 2.
Rehabilitation of homonymous scotomata in patients with postgeniculate damage of the visual system: Saccadic compensation training.
Thus, linear saccadic eye model and eye blink were analyzed using wavelet transformation and fuzzy logic to classify different eye movements in real-time [11].
