We went to the eye doctor for Sam today. He's had drainage coming from one eye for several months and the other eye started last month. The cause is a blockage in the tear duct so the tears don't drain like they should. The doctor probed these ducts, but first they had to strap him down and numb his eyes - the poor guy. It looked like an awful experience. I sure don't ever want to go through it. It seemed to look harder then it should have been and we heard a "pop" when the blockage gave way. She said it was the most plugged she's seen in a long time. OOOOWWW! He seems to be doing fine now. Let's just hope it worked and was worth all that pain and anguish
