A blocked tear duct prevents tears from exiting the eye properly. Tear ducts are the draining system for tears and can sometimes fail to open due to inflammation or infection. A blockage can cause watery, irritated eyes that become red and uncomfortable. It is typically easily treated and will often clear up on its own with no treatment, especially in children. Recurrent or severe blockages can sometimes lead to more invasive procedures and even surgery.
The most common symptoms of a blocked tear duct are excessive watery eyes, redness to the corner of the eye, and crust developing on the eyelids. Swelling can also develop that is painful. Some patients also suffer from blurred vision and discharge coming from the affected eye. The condition can also cause other eye infections like conjunctivitis to occur.
