"Saccadic eye movements and their neurological control signals change significantly as the human fatigues. Electronic instrumentation with a band-width extending from DC to 1 kHz enabled the recording of anomalous looking saccadic eye movements that occurred as the subject's physiological state changed. Fatigue can produce: overlapping saccades in which the high-frequency saccadic bursts should show large pauses; glissades in which the high-frequency bursts should be much shorter than appropriate for the size of the intended saccades; and low-velocity, long-duration, non-Main Sequence saccades in which the motoneuronal bursts should be of lower frequency and longer duration than normal. As few as 30 saccades of 50 deg magnitude or a longer sequence of saccades as small as 10 deg can produce these aberrant eye movements and their concomitant neuronal firing pattern variations. The effects of fatigue could explain some of the variations between and spread within published data for velocity vs amplitude of human saccadic eye movements. Measuring the resistance to eye movement fatigue could become either a common clinical tool for diagnosing specific or general disease states, or a research tool for studying dyslexia or fatigue."

So I'm fatigued when it happens? Well duh. It happened when Vyvanse wore off.. But there's also a lot of psychological issues too like lack of focus - And people with ADHD tend to have these movements, analysis suppression, etc..

Ah nvm I'll come back to this later. I'm gonna talk to my doctor and an optometrist because it's not normal to be re-focusing 50 times a second during a panic attack no?

More on this;

"The discriminant analysis resulted in three eye movement measures; the scanpath length during the free viewing test, the horizontal position gain during the fast Lissajous paradigm of the smooth pursuit test, and the duration of fixations during the far distractor paradigm of the fixation stability test. An integrated score using these variables can distinguish patients with schizophrenia from healthy controls with 82% accuracy."
