Hi T.,
The book that I live by when I have questions like this, The Baby Book by William and Martha Sears. It is my baby Bible. Run out and get a copy!
Here's what they say about clogged tear ducts:
Gently massage the tear duct that is located beneath the tiny "bump" in the nasal corner of the eye. Massage in an upward direction (toward the nose) about six times. Do this tear-duct massage as often as you think of it - for example, before each diaper change (he's probably potty trained?). Your doctor may prescribe antibiotic ointment or drops to treat this infection. Occasionally this doesn't work and it becomes necessary for an eye doctor to open these tear ducts by inserting a tiny wire probe into them. This is usually a short, minor office procedure but may require outpatient surgery under general anesthesia. Sometimes in an older child this discharge may be caused by an eye infection called conjunctivitis.
Hope this helps!!
