Saccade - Wikipedia, the free encyclopedia
A saccade is a fast movement of an eye, head or other part of an animal's body or device. It can also be a fast shift in frequency of an emitted signal or other quick change. Saccades are quick, sim...

The technical problem is that saccades are very fast, and ENG manufacturers generally have optimized their equipment for slow things (like caloric nystagmus). Sampling rates of 15-30/second are fine for calorics, but just don't do much good for something that moves at 600 degrees/second.

A definition of the saccadic motions employed in vision. ... The major saccades are generally larger than 1.2 degrees and associated with the low frequency, less than 5 Hz, tonal response of the oculomotor muscles. They can be subdivided into the large, >6.2 degrees, and small saccades, between 1.2 and 6.2 degrees.

P4 can be found fairly reliably when the eye is still, but during saccades the smeared P4 is below the threshold of the camera and it disappears. Towards the end of the clip there are also some false locks on what I think is P3 (a diffuse bright blob that moves around with the eye movement).

Normal values for the velocity of 20 degree saccades are given in table 2. Note that velocity is very sensitive to the method by which saccades are recorded. Normal saccadic velocity values obtained via infra-red methods or scleral search coil recordings are usually higher than those obtained via EOG recordings.
