Any body know remedy for blocked tear duct?

Depends on situation. This is common in newborns & given some time and growth the blockage can clear on its own as the duct becomes larger.If still blocked at 6m & unresponsive to simple measures, an ophthalmologist may need to probe the duct & clear the blockage. One simple measure involves rolling the tip of the finger over the inner corner of the eye over the tear sac which may push any blockage down the duct.
