Nystagmus as a Predictor

So it seems that I'm finally experiencing the effects of picking a topic that is very specific: there does not seem to be much directly related to the optokinetic and vestibulo-ocular reflexes. There is, however, a news article I found today about nystagmus, which confirms something I was speculative about earlier: the ability of nystagmus to predict diseases.

The news story described the vision problems that can be related to multiple sclerosis, and cited that in about 75 percent of multiple sclerosis patients, nystagmus is a symptom as objects in the field of vision seem to "jiggle", causing loss of balance and perceptive abilities.

In terms of my research, this seems to be an effect of both the optokinetic and vestibulo-ocular reflexes, in that it is already known that nystagmus relates to problems with the eye, but the fact that it causes a moving field of vision sensation likely means that the optokinetic reflex is not working well enough to warrant correct vision perception.
