Complications
Because your tears aren't draining the way they should, the tears that remain in the drainage system become stagnant. This promotes growth of bacteria, viruses and fungi, which can lead to recurrent eye infections and inflammation.
Any part of the tear drainage system, including the clear membrane over your eye surface (conjunctiva), can become infected or inflamed because of a blocked tear duct.
