There is something wrong with my left eye, or vision in general, or possibly something neurological/brain related, but opthamologists, neuro optics, CT Scan, etc... couldnt find anything wrong several years ago.

I see visual trails after looking at something for a few seconds, and looking away, or crossing the path of something brighter than the surroundings. I see a copy of that object in my vision for 2-3 seconds, predominantly in my left eye. This eye seems very oversensitive to light. For example, if indoor light reflects off a clear piece of plastic or a CD, even if I'm not looking it, it's almost as bad sun reflected off a car mirror. I find it hard to maintain eye contact(not because of shyness), and if i look from a sunlit window to a closer object, my left eye will constict and feel like it's momentarily blinded, when the light isnt even that bright. Even in dim light this eye seems to take twice as long to refocus as my right. I also see my vision pulsate/dim with heartbeat in my left eye after doing anything strenuous. In public areas, or a big open store, my eyes react like they dont know what to look at, like everything is overwhelming as well, and I can't browse around casually. This has even happened when I've been on anti-depressants, so I'm not sure if it's anxiety. It seems to be slowly getting worse. To me it seems like something behind the eye or otherwise is causing pressure so it doesen't track with the right properly.

Also, my left ear nearly always feels full, pops, stings, pulsates, and seems to act worse when my eyes are acting up. This is not recent either and has been going on since my original eye complaints several years ago. Do I have an inner ear problem? Could this cause visual problems in one eye?

Has anyone out there had something similar and ever came to a diagnosis? I fear this is beyond the scope of anxiety, and have been wondering if it's everything from Menieres, Chiari Malformation, blood clot, you name it. I had been ok with it for several years, but either it has gotten worse recently, or recent anxiety has made it seem worse. Either way I'd like to figure out what it is.

I've recently had a full blood workup done and that came back negative for diabetes, or any other disorders a standard blood test would pick up that would cause an eye related problem. The only specialists that I did not see several years ago was a neurologist, and an ENT.

Any ideas?
