Wait. Contemporary nystagmus == saccades? I haven't tracked the cause down yet - I know it's a nerve issue of some kind - but sometimes my jaw, arms or eyes (yup) can occasionally jump. My jaw and arms jump when I'm nervous (or have a buildup of too much nervous energy/excitement), while my eyes jump when I'm trying to focus on something too hard, they drift, and I try to course-correct too hard. (I think half my brain is aware of the drifting, but the other half, the part that would make the fine motor movements to keep my eyes locked, is happily whistling away blithely in a corner somewhere.) When my eyes jump and I overcorrect when I fail to re-point them where they need to be, I usually have a second or two where I'm not technically blind but I need to let my eyes refocus and remember their purpose in life (if you will) :P I always thought this was nystagmus (read the term online one day and went "!!! that's what it's called!")... but now I wonder, is what I'm dealing with something else? (An aside: I'm really, really bad at tracking moving objects in space. If someone else is holding onto something and I'm expected to look at it, I have to hold it instead. No other alternative.)
