Eye and Ear Connection?

For the past year and some months my ears have been draining a clear fluid. This happens at random times, while driving home or working on the computer, or more specifically every time I put my contacts in or take them out. This also happens when I cry. I can feel it start to drain before it actually exits my ears. They both drain at the same time and it is enough fluid that I have to get a tissue to soak it up or it will run down my neck. I have seen two ENT's who do not know what it could be, had never heard of such a thing and have both examined my ears and said there are no holes in the eardrum. One blew boric acid into the ears to see if that would dry them up, it had no affect. Could you possibly have some insight for me on what it might be?
