Tears are a liquid that is used to hydrate and protect the eye permanently if it is attacked or affected by any disease. They are produced by the tear glands and then drained from the nasal conjunctival fundus through the tear ducts. These tear ducts can be affected by infections or diseases that can have serious consequences.
Among these consequences and repercussions is the permanent lacrimation called epiphora. This excessive tear flow usually occurs because of blocked tear ducts. This problem affects adults and babies alike and may require tear duct surgery to allow the eye to regain its function.
