I frequently have this problem with tracking moving objects in my vision. The best explanation I've found is Pulfrich's effect, which is a neurological problem caused when one eye is transmitting information at a slower rate than the other eye. Since I've had optic neuritis, I know that there's some damage to the white matter of the optic nerve - and one eye certainly sees a little darker than the other.
Basically what's happening is that your brain is receiving two separate sets of information, and you're trying to resolve both of them so that what you're seeing makes sense. This leads to a feeling of disquiet, and a sensation that you're out of control of the situation.
On my bad days, I find it really difficult to drive! I also avoid tracking things in my vision unless I need to be looking at them.
1. The maxillary sinus issue probably has nothing to do with this and probably is not significant, but you would want to ask your doctor about this.
2. The out of sync feeling needs to be evaluated to make sure it is not a seizure.
3. The feeling of things moving may be a form of oscillopsia, with the feeling of the world moving back and forth.
I would do the following:
1. Talk to your neurologist.
2. Perhapse see a neuro-ophthalmologist to make sure you have no eye movement problems.
3. Consider the use of a medication called memantine (Namenda) which you should ask your neurologist about for oscillopsia (if that is what is diagnosed).
Can this be an MS symptom or something else. I have seen two neurologists and they advise nothing. Meanwhile I cannot drive to work and feel safe.
