Does caffeine affect nystagmus?

Results: Caffeine was associated with higher peak saccade velocities (472 ± 60° s-1) compared to placebo (455 ± 62° s-1). Quick phases of optokinetic nystagmus were also significantly faster with caffeine, whereas pursuit eye movements were unchanged.

What drugs cause nystagmus?

It is not something I could test, since I already have Nystagmus, but this theory sound plausible to me.

What is alcohol nystagmus?

Positional Alcohol Nystagmus: caused when alcohol alters the specific gravity of the blood versus the vestibular fluid Neurological nystagmus: consisting of optokinetic, physiological and gaze nystagmus Optokinetic nystagmus: occurs when eyes fixate on objects that suddenly move or when eyes view sharply contrasting images

How does caffeine affect your eyes?
