This happened to my dog when he was younger, but just in one eye. The vet said the duct was blocked, and he underwent a procedure to flush it to clear the blockage. It was back again about a week later. Shortly before this happened, I had just switched over his food to another brand. The problem stuck around for a month or so, then disappeared a few days after I switched him back to his old food. I'm sure there was an allergy/intolerance that was food related. You may want to look into this.
