Blocked Tear DuctsTopic OverviewWhat is a blocked tear duct?Tears normally drain from the eye through small tubes called tear ducts that stretch from the eye into the nose. A blocked tear duct occurs when the opening of the duct that normally allows tears to drain from the eyes is obstructed or fails to open properly. If a tear duct remains blocked, the tear duct sac fills with fluid and may become swollen and inflamed, and sometimes infected. Blocked tear ducts occur in about 6 out of 100 newborns.1 A blocked tear duct that is present at birth (congenital) is called nasolacrimal duct obstruction. Blocked tear ducts are uncommon in adulthood. They mostly occur in older adults and are usually the result of aging or an injury. What causes a blocked tear duct?In babies, the most common cause of a blocked tear duct is the failure of the thin tissue at the end of the tear duct to open normally. Other less common causes of blocked tear ducts in children include:
In adults, tear ducts may become blocked as a result of a thickening of the tear duct lining, nasal or sinus problems, injuries to the bone and tissues around the eyes (such as the cheekbones), infections, or abnormal growths such as tumors. What are the symptoms?Usually, the first symptom
of a blocked tear duct is excessive tearing, ranging from a wet appearance of
the eye to tears running down the cheek. Babies who have blocked tear ducts
usually have symptoms within the first few days to the first few weeks after
birth. If infection occurs in the
eye's drainage system The symptoms of a blocked tear duct may get worse after an upper respiratory infection, such as a cold or sinus infection. Also, symptoms may be more noticeable after exposure to wind, cold, and sunlight. How is a blocked tear duct diagnosed?A blocked tear duct is diagnosed based on a medical history and a physical exam. Also, tests may be used to measure the amount of tears or to see whether tears are draining normally from the eyes. Other tests can help your doctor find out where the blockage is or how it was caused. How is it treated?Babies born with blocked tear ducts usually do not need treatment. Most blocked ducts clear up on their own by 1 year of age. But home treatment measures that keep the eye clean and help drain the duct can help prevent infection. Antibiotics usually are needed if signs of infection appear, such as redness, swelling, or yellowish discharge. If the duct remains blocked after the baby is 6 months to about 1 year old, a probing procedure may be done. Probing successfully opens the duct for about 90 out of 100 babies who have blocked ducts.1 Probing is not usually done for adults because it rarely helps. Other treatments for a blocked tear duct may include antibiotics for infection or surgery for structural problems or abnormal growths. Frequently Asked Questions (FAQs)

CauseThe most common cause of a blocked tear duct is the failure of the thin tissue, or membrane, that covers the tear duct (lacrimal duct) to open normally into the nasal passage shortly after birth. This disrupts the usual drainage system for tears. Symptoms usually are not noticed if the blockage resolves on its own before a baby starts producing tears. Normally, tears start forming within the first few days to weeks following birth. Less common causes of blocked tear ducts in babies can include:
Blocked tear ducts in adultsThe cause of blocked tear ducts in adults is usually related to another disorder or an injury. For example, a blocked tear duct may result from a thickening of the tear duct lining, abnormal tissue or structures in the nose, or complications of surgery on or around the nose. These types of problems are more likely to occur after age 60. SymptomsBabies with blocked tear ducts usually have symptoms after they start producing tears, which can be any time from the first few days to the first few weeks after birth. Symptoms often affect only one eye and usually include:
The symptoms of a blocked tear duct may get worse after an upper respiratory infection, such as a cold or sinus infection. Also, symptoms may be more noticeable after exposure to wind, cold, and sunlight. What HappensTear ducts can be fully or partially blocked. The blockage causes tears to back up inside the tear duct system and may cause the tears to overflow onto the face (epiphora). The blockage may also allow infection to develop in the tear ducts as bacteria and other substances collect in the eye. If the tear duct opens by itself, the infection may clear up without treatment. Most blocked tear ducts are present at birth (congenital) and resolve on their own before a baby is 1 year old.1 A few babies may need probing to open the ducts. Probing done around age 1 usually works well, and most babies don't need it done again.2 A blocked tear duct by itself usually does not permanently affect a baby's vision or increase the likelihood of having other eye problems. Infections may develop many times in the affected eye. In rare cases, infection may spread to the eyelids and skin around the eye (periorbital cellulitis). Sometimes a pus-filled sac (dacryocystitis) also forms. In adults, most blocked tear ducts are caused by infection, structural problems related to injury or surgery, or abnormal growths within the drainage system. Treatment for a blocked tear duct depends on the cause.
What Increases Your RiskRisk factors for a blocked tear duct include:
When To Call a DoctorCall your doctor if you or your baby has:
The following signs may point to other problems with the tear duct. Call your doctor if you have or if your baby has:
Call your doctor if you notice excessive tearing in one or both eyes and have:
Watchful WaitingWatchful waiting for 1 to 2 weeks is appropriate in most cases of blocked tear ducts in babies. They usually clear up on their own or with treatment before the baby's first birthday. Watchful waiting for 1 to 2 weeks also is appropriate for adults with a blocked tear duct without signs of infection. The condition may clear up on its own. Watchful waiting is not appropriate if you develop excessive tearing in one or both eyes and you:
Who To SeeA child or an adult with a blocked tear duct may see:
To prepare for your appointment, see the topic Making the Most of Your Appointment. Exams and TestsA blocked tear duct is diagnosed based on a medical history, a physical exam, and other testing as needed. Tests for children and adults may include:
Additional tests are sometimes used, although usually only with adults. These tests may include:
Treatment OverviewMost of the time, a blocked tear duct clears up on its own by the time a baby is 1 year old. But you can help prevent infection by keeping the eye clean and massaging the area of the blockage so fluid does not build up in the duct. If signs of infection develop, your baby may need an antibiotic medicine. If the duct remains blocked after your baby is 6 months to 1 year old, probing may be done to open the duct. In rare cases, babies with blocked tear ducts have a more severe problem that requires more complicated surgery. In adults, treatment depends on the cause of the blockage. If the duct is blocked due to a long-term (chronic) infection, antibiotic medicines are used. Surgery for blocked tear ducts may be needed for structural problems of the drainage system (such as from injury or age-related changes) or abnormal growths. PreventionMost blocked tear ducts cannot be prevented. The majority of blocked tear ducts are present at birth (congenital) when the thin tissue covering the tear duct does not open normally. But you can help prevent some conditions that can cause blocked tear ducts, such as:
If your baby has blocked ducts, limit his or her time in the wind, cold, and sunlight. This can help prevent symptoms from getting worse. Home TreatmentBlocked tear ducts most often occur in babies. If your baby is born with a blocked tear duct, it will usually clear up on its own by 1 year of age. You can help prevent infection in your or your baby's blocked tear duct by keeping the eye clean and using gentle massage techniques. Wash your hands before and after touching the eye area. To keep the eye clean:
Massage should only be used under the advice and direction of a doctor. Usually, it is done 2 or 3 times a day for several months. MedicationsBlocked tear ducts prevent the eye's drainage system from working properly and make it prone to infection. Antibiotics are needed if signs of infection develop, such as redness, tenderness, swelling in or around the eye, and mucus that looks like it contains pus. Some antibiotic solutions and ointments are applied directly to the eye (ophthalmic antibiotics), while some are taken by mouth (systemic antibiotics). They may also be used to try to prevent infection, although they have not been proved effective for this purpose. Antibiotics for more serious or long-term (chronic) infections can help reduce scarring of the drainage system for tears. To learn the best way to use medicines that you put in your eye, see: SurgeryMost babies born with a blocked tear duct will not need surgery. But when surgery is needed, probing is usually done. Probing involves passing a thin wire through the blocked tear duct to open it. Probing may be done in the doctor's office under a local anesthetic (numbing eyedrops) for babies younger than 1 month of age. General anesthesia, which is usually done in an outpatient hospital setting, can be used for older babies. The doctor is able to evaluate your baby's tear duct more thoroughly if general anesthesia is used. Also, if needed, an additional procedure to resolve the blockage often can be performed at the same time and prevent the need for another surgery. For adults, treatment for a blocked tear duct depends on its cause. Probing is typically not effective with adults, and other surgical procedures are usually used. Other types of surgery for a blocked tear duct in babies or adults may include breaking a nasal bone, placing a tube in the tear duct, or surgically creating a new tear duct. Surgery ChoicesSurgical options for a blocked tear duct include:
Surgical options that are rarely used for children—and only after the above procedures have failed—include:
When you talk about surgery options with your child's
doctor, use this
surgery information form In adults, treatment for a blocked tear duct depends on the cause of the blockage and can include any of the above choices. What To Think AboutAbout 6 weeks after a surgical treatment, you or your child will most likely visit the doctor for an eye exam and may be tested again with the fluorescein dye disappearance test.
