I have a condition called nystagmus[1] which makes my eyes saccade constantly. It mostly happens when I look to the left or right, with what's called a "null point" in the middle. Having a null point in the middle is a lucky break.
It doesn't affect my day-to-day, which I think is surprising. In fact I have very good hand-eye coordination and visual perception, which may be a side-effect of constantly having to track moving objects.
It's also a symptom of being drunk, or a brain injury. Medical students are always very concerned and ask whether I've hit my head, and I often get breathalysed when I'm pulled over.
I get nystagmus from time to time (maybe once a year) because of positional vertigo, but I have since learned to "fix" it by applying the Epley manoeuvre myself. I guess yours is not treatable though.
