INFECTIONS AND EYE IRRITATIONSINFLAMMATION OF THE LACRIMAL DUCTS INFLAMMATION OF THE LACRIMAL DUCTS Inflammation of the tear ducts, or dacryocystitis, is inflammation of the tear drainage system in one or both eyes that causes excessive tearing, and sometimes redness and discharge despite the absence of allergies, colds, or other ailments. . WHAT ARE THE CAUSES OF INFLAMMATION OF THE TEAR DUCTS? In adults, infection develops when the tear ducts are blocked, sometimes as a result of the natural growth of surrounding bones. Bone growth can narrow the tear ducts, creating a blockage, which causes pyogenic germs to accumulate and proliferate (producing pus). Many newborns are born with the membrane in the tear duct not opening or too narrow enough to prevent the normal flow of tears. This is a very common situation and, in most cases, it is overcome within the first year. However, if the disorder continues after the first year of life, a small, painless surgery is done to open the duct (typically takes 5 minutes, and is done in the doctor's office).
