• #1 Blocked Tear Duct: Causes, Symptoms, Treatment & Prevention

  https://my.clevelandclinic.org/health/diseases/17260-blocked-tear-duct-nasolacrimal-duct-obstruction

  A blocked tear duct is a condition that happens when something keeps tear fluid from draining out of your eyes properly. These blockages slow or stop the flow of tear fluid, causing it to back up in the tear duct system and into your affected eye. The medical term for this condition is nasolacrimal duct obstruction. […] Tear duct blockages can happen for a few different reasons. Some are congenital, meaning you have them when you’re born. Others develop later in life. […] Congenital tear duct obstruction usually happens because a child still has an unbroken membrane where the valve of Hasner should be. That means fluid can build up inside the lacrimal duct. Over time, the accumulated tear fluid can cause the duct to expand. It can also lead to an infection of the tear duct or other parts of the tear system.

  A blocked tear duct is a partial or complete blockage in the pathway that carries tears from the surface of the eye into the nose. […] In children, the duct may not be completely developed at birth. It may be closed or covered by a thin film, which causes a partial blockage. […] In adults, the duct can be damaged by an infection, injury, or a tumor.

  Instances of a blocked tear duct in babies are fairly common, and they are usually due to birth abnormalities. Experts estimate that 20% of babies have a blocked tear duct at birth. […] Adults most frequently develop a blocked tear duct as a result of: an infection in or near the eye, an injury in or near the eye, swelling around the eye, a tumor. […] For older adults, the abnormal narrowing of the tear drainage system is a common cause of a blocked tear duct. […] However, there are many other possible causes of a blocked tear duct. They include: chronic sinus infections, which can damage and block nasal tissue over time, scar tissue from an injury, such as a broken nose, age-related narrowing of the puncta, which are holes in the eyelids through which tears drain, nasal polyps, conjunctivitis and viral infections, craniofacial abnormalities, such as a deviated septum.

  Babies are more vulnerable to blocked tear ducts because their ducts are tiny. “The tear system isn’t fully developed at birth. As a result, infants often have narrower tear ducts,” says Kristen Cook, MD, a board-certified pediatrician in southeastern Wisconsin. “This narrowing leads to a partial blockage within the tear duct. Sometimes, an infant will be born with extra tissue in the nasolacrimal duct, which can also cause a blocked tear duct.” […] The American Academy of Ophthalmology estimates that up to 20 percent of babies are born with a blocked tear duct. Fortunately, the condition usually resolves on its own within four to six months.

  Tear duct obstruction keeps tears from draining through this system normally. […] The most common cause is a membrane at the end of the tear duct (valve of Hasner). […] Other causes of blocked tear ducts in children include: Absent puncta (upper and/or lower eyelids), Narrow tear duct system, Infection, Incomplete development of the tear duct that does not connect with the nose. […] Blockage of the drainage system causes tears to well up on the surface of the eye and overflow onto the eyelashes, eyelids, and down the cheek. […] Severe cases lead to a serious infection of the tear duct system (dacryocystitis). […] If the tear duct remains blocked after 8 to 10 months of age, there is much less of a chance for the obstruction to resolve on its own and a procedure such as nasolacrimal duct probing may be recommended. […] Dacryocystitis is a rare complication that can occur in a blocked tear duct. […] If the tear duct is blocked both in the upper and lower part, amniotic fluid can get trapped in it.

  Tear duct blockages can also happen because of other conditions or be more likely to happen under certain circumstances. These are more likely to happen higher up in your tear duct system (or in parts that aren’t technically tear ducts, but they connect to the ducts). […] Examples include: Infections. Chronic infections of your eyes or surrounding areas can contribute to scar tissue buildup. Sometimes, that scar tissue can cause narrowing and form a blockage. […] Injuries. Trauma to your face, eye or nose can cause swelling and tissue changes around your tear system. Swelling or tissue changes affecting any part of the system can cause or contribute to a blockage. […] Narrow tear ducts (dacryostenosis). Sometimes, your tear ducts are narrow when you’re born, or they get narrower during your lifetime. Either can cause or contribute to a blockage.

In children and adults, a blocked tear duct is an acquired condition, associated with more serious underlying issues. […] Sometimes, a duct can become blocked by a tiny particle of dirt or grit that lodges in the eye and migrates into the ducts. Other times, tear ducts can be blocked by tumors or other growths, by an injury to the eye or nose, or even from some medical treatments, like chemotherapy. […] Most often, however, an infection causes tear ducts to become blocked. […] Blocked ducts also are more common with age. As you get older, the tiny openings and canals that allow tears to drain from your eyes get narrower, making it easier for blockages to occur.

It will usually open on its own within a few months. […] Less often, tear ducts get blocked because the tear drainage system didn’t form correctly in the womb. […] In adults, tear ducts can get blocked for lots of reasons: The holes in the corners of the eyes, the puncta, narrow due to age. Trauma cuts the drainage duct. Harmless debris or small particles get stuck in the duct. A broken nose or other injury leaves scar tissue that presses on the tear duct. Small, rounded growths called polyps form in the nose and block the duct. An infection in the eye or nose causes swelling around the tear duct. Conjunctivitis (pinkeye), an infection of the conjunctiva, the clear membrane that covers the eye, is one common infection that can cause blocked tear ducts. A tumor presses on the drainage system. Sinus surgery damages the tear ducts or the holes that drain to them. Eye drops to treat glaucoma make the conjunctiva and the tear ducts swell.

However, in some patients there are some possible correlations with these conditions: […] Chronic sinusitis with a history of nasal or sinus surgery, tumor in the nasal passageway or sinus. […] Accident victims who required surgery around the eye and the bridge of the nose, which may have put pressure on the tear duct.

[…] Older age leads to narrowing of the punctual openings, slowing tear drainage. […] Dacryoliths, a collection of shed epithelial cells, lipids, and amorphous debris within the nasolacrimal system. […] Nasal septum deviation, rhinitis, and turbinate hypertrophy. […] Damage to the nasolacrimal system due to trauma of the nasoethmoid region (the central part of the face) or endoscopic/endonasal procedures. […] Neoplasm within the nasolacrimal system.

In children and adults, a blocked tear duct is an acquired condition, associated with more serious underlying issues. […] Sometimes, a duct can become blocked by a tiny particle of dirt or grit that lodges in the eye and migrates into the ducts. Other times, tear ducts can be blocked by tumors or other growths, by an injury to the eye or nose, or even from some medical treatments, like chemotherapy. […] Most often, however, an infection causes tear ducts to become blocked. […] Blocked ducts also are more common with age. As you get older, the tiny openings and canals that allow tears to drain from your eyes get narrower, making it easier for blockages to occur.
