Wink, wink... 
Unequal pupils CAN indicate brain involvement. (trauma, infection, etc)
I had this "unequal pupil" thing first happen many years ago. When it happened I would feel a bit of a "duh" feeling (more so than normal... kind of a duh and light buzz too)... and it got happening so often that I could tell when the pupils were unequal just by the "duh" feeling I would get.
My eyes also became slow to react to light. One side was slow.. and the other even slower. Sometimes the left pupil would get "stuck" open and stay that way for days.
Although MANY doctors noted this situation by seeing it on their own... NEVER did they do anything about it.. and they refused me treatment for Lyme... and refused to listen when I said I was having trouble with my brain/head/neck. They labeled it Addie Robertson's pupil at one point.. and a few other fancy names.. but they all noted it in the charts and did nothing about it. And they called it several fancy names.. all meaning the one pupil was bigger than the other.
The bad news is.. it was happening when I got what I call... "irreversible brain damage".
That is when all the really bad things happened to my brain and the brain sort of "fried".
I lost many skills at that time... and I have never gotten back what I lost.
I have been able to re-train my brain for a number of basic functions... but never was able to retrieve my old memory and do simple things again with out re-learning them from the beginning.. like figure out how to get dressed, how to drive... how to cook an egg... etc.
I also still have no memory of highschool (going to classes, events, etc.)... friends and events from various time periods in my life, and whole years or segments of my life are still "missing".
I am unable to recognise someone's "face" anymore.. even my own family members. Sounds weird... but true. I go by other things to identify them now... their walk.. their voice, etc.
Much of the cognitive stuff (damage/problems) happened then also.
I am now at a 2nd or 3rd grade level for certain skills.. and my IQ dropped over 20 points at that time.
Luckily I could afford the drop in points! HA!

The way they knew the brain was affected.. besides the fact I was a bumbling idiot.. was the difference in scores on my cognative testing, over time.
In one area I did well... and had learned to compensate for many things I had lost.. in other areas I was REALLY bad.
The big difference in points from one set of tests to the other (on the same day) indicated my problem was due to an "organic brain syndrome." Over time... the total scores also became worse when I was untreated for the infections.
I was classified as moderately mentally retarded from the damage done and the scores.
Prior to Lyme, I was in the "normal" range.
Well, as normal as a Tincup can be! hehehe
The good news is...
With proper treatment I think the down hill progress has basically stopped or slowed down... IF I stay on the antibiotics.
I still have problems with the eyes acting up here and there.. and I am usually quite physically "bad" when the eyes start looking unequal again.
BUT..
The neuro chiro works specifically with this situation.. and is able to "adjust the brain" and kick it in gear (stimulate it) so the eyes no longer do this... and the brain and eyes work together so I function better and feel better.
It also kicks in brain functioning so my temperature regulates, my mental status improves, my hormones start working again.. or it kick-starts the organs that are suppose to produce the hormones so they work... etc.
He insists though that I take my antibiotics because he can NOT undo the infection in the brain or anywhere else.. which is the CAUSE of the problem.
Most neuro chiro's don't like "drugs".. but he has made an exception for Lyme because he has seen first hand what it does to my brain.. and my body... and documents how much better I am when ON meds.. and how bad I slide backwards when off them.
He actually can tell when I am on my antibiotics and when I have stopped them... because my eyes tell on me!!! I don't say a word.. and he KNOWS!!!
And he jumps on me for stopping them!! He also can tell when I am herxing... but that could be because of my "lovely" personality at the time... HA! EVIL Tincup!
My eyes have been acting up again recently... and I had stopped going there for the summer... and had stopped my meds on/off too.
He said after I returned recently that he had not seen my pupils this bad since I first started going to him... and maybe they are even worse now than then.
And yes.. while I was going there regularly.. my pupils never did that unequal thing... or if they did.. it was so mild I couldn't tell.
The point to all this rambling...
Consider the fact the brain may be "infected" or "affected" at this time.
I want you to know what happened to me.. so it won't happen to you if at all possible.
I can't and WON'T say this is happening to you.... it could be other things just as easily. And remember.. I am NOT a doctor.
I just want to throw this in here so you are aware it can happen.
Otay?
