What can harm the tear duct?

Tear ducts can be harmed by various factors, including infections, inflammation, or blockages caused by debris or tissue growth. Trauma to the eye area, such as injuries or surgical complications, can also damage the tear duct system. Additionally, conditions like dry eye syndrome and certain autoimmune diseases can lead to dysfunction or scarring of the tear ducts. Regular eye care and prompt treatment of eye infections can help protect tear duct health.
