Blocked tear duct

A blocked tear duct is when the eye'due south drainage organization for tears is either partially or completely obstructed. Tears cannot drain normally, causing a watery, irritated or chronically infected eye.

Most of your tears come from your lacrimal glands, which are located in a higher place each heart. The tears flow down the surface of your eye to lubricate and protect it, and and then drain into tiny holes (puncta) in the corners of your upper and lower eyelids. The tears then travel through the small canals in the lids (canaliculi) to a sac where the lids are attached to the side of the nose (lacrimal sac), then down a duct (the nasolacrimal duct) earlier emptying into your nose, where they evaporate or are reabsorbed.

In adults, the tear duct obstruction tin can result from an eye infection, swelling, injury or a tumor.

Blocked tear duct newborn

A baby can be born with a blocked tear duct (a congenital blocked tear duct) and information technology affects almost xv-20 pct of normal newborns. It is estimated nearly 15-20 percent of newborns have a blocked tear duct, but the condition ordinarily resolves on its ain within 4 to half-dozen months. If the blockage persists by 4 to half-dozen months, the chances that it volition open on its own are less than 20 percent and falling every day the child gets older. Most often, surgery is recommended before a twelvemonth of age.

The lacrimal (tear) appliance

The lacrimal (tear) apparatus (Figure 1) is a group of structures that produces and drains lacrimal fluid (tears) in a procedure called lacrimation. The lacrimal apparatus consists of the lacrimal (tear) gland and a series of ducts that drain the tears into the nasal cavity. The lacrimal gland, about the size and shape of an almond, is nestled in a shallow fossa of the frontal bone in the superolateral corner of the orbit. Near half-dozen-12 short ducts lead from the gland to the surface of the conjunctiva.

The lacrimal (tear) glands are supplied by parasympathetic fibers of the facial (7) nerves. The lacrimal fluid produced by these glands is a watery solution containing salts, some fungus, and lysozyme, a protective bactericidal enzyme to foreclose infection. Tear fluid protects, cleans, lubricates, moistens the eyeball and delivers oxygen and nutrients to the conjunctiva. After being secreted from the lacrimal gland, tear fluid is spread medially over the surface of the eyeball by the blinking of the eyelids. Each lacrimal gland produces about one mL of lacrimal fluid per day

Later on washing across the centre, tears collect near the medial commissure and period into a tiny pore, the lacrimal punctum, on the margin of each eyelid. The punctum opens into a short lacrimal canaliculus, which leads to the lacrimal sac in the medial wall of the orbit. From this sac, a nasolacrimal duct carries the tears to the junior meatus of the nasal crenel; thus an abundance of tears from crying or watery eyes can result in a runny nose. Once the tears enter the nasal cavity, they unremarkably flow back to the throat and are swallowed.

An obstacle of the tear ducts may occur due to numerous reasons (aging, trauma, inflammatory weather, medications and tumors) and cause numerous signs and symptoms ranging from wateriness or tearing to discharge, swelling, pain and infection. These signs and symptoms may consequence from the tear drainage organisation becoming obstructed at any point from the puncta to the nasal cavity.

Blocked tear duct complications

Because your tears aren't draining the way they should, the tears that remain in the drainage system go stagnant. This promotes growth of bacteria, viruses and fungi, which can lead to recurrent eye infections and inflammation.

Any role 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.

Blocked tear duct causes

A blockage can occur at any point in the tear drainage arrangement. When that happens, your tears don't drain properly, giving you watery eyes and increasing your take a chance of heart infections and inflammation.

Babies in utero accept a sparse membrane that seals the nasolacrimal duct. In newborns, a blocked tear duct may exist the result of that membrane not opening every bit it should at birth.

Another cause of blocked tear duct may exist chronic nose infections. Chronic sinusitis may irritate the tissues and form scars, which block the tear duct system.

Other causes of blocked tear duct:

• Abnormal development of the skull and face up (craniofacial abnormalities), like those in Down syndrome or other disorders, increases the likelihood of blockage of the tear ducts.
• Age-related changes in older adults tin can crusade blocked tear ducts, including narrowing of the punctal openings.
• Eyedrops. Rarely, long-term use of certain medications, such as eyedrops used to treat glaucoma, can cause a blocked tear duct.
• Nose trauma, such as a broken olfactory organ; scar tissue can block the tear duct.
• Injury or trauma. An injury to your face up tin cause bone damage or scarring about the drainage system, disrupting the normal flow of tears through the ducts. Even modest particles of dirt or loose skin cells lodged in the duct tin cause blockage.
• Nose polyps, a growth from the lining of the olfactory organ (affecting some people who have nasal allergies), can obstruct the tear duct system
• Conjunctivitis, infection and inflammation of the conjunctiva, the thin membrane covering the eye. In rare cases, the tear duct system may become infected and blocked, especially subsequently some viral infections. Chronic infection or inflammation of your eyes, tear drainage organisation or nose can cause your tear ducts to go blocked.
• Tumor, a tumor in the olfactory organ or anywhere along the tear drainage system tin cause blockage of the tear duct system and forbid drainage.
• Cancer treatments. A blocked tear duct is a possible side effect of chemotherapy medication and radiation handling for cancer.

If your eye has been watery and leaking or is continually irritated or infected, yous should encounter your ophthalmologist.

Risk factors for blocked tear duct

Certain factors increase your risk of developing a blocked tear duct:

• Age and sex. Older women are at highest chance of developing blocked tear ducts due to age-related changes.
• Chronic eye inflammation. If your eyes are continually irritated, blood-red and inflamed (conjunctivitis), you're at higher risk of developing a blocked tear duct.
• Previous surgery. Previous eye, eyelid, nasal or sinus surgery may have caused some scarring of the duct organization, perchance resulting in a blocked tear duct afterward.
• Glaucoma. Anti-glaucoma medications are often used topically on the eye. If you've used these or other topical heart medications, yous're at higher take chances of developing a blocked tear duct.
• Previous cancer treatment. If you lot've had radiation or chemotherapy to treat cancer, particularly if the radiation was focused on your face or head, you're at college risk of developing a blocked tear duct.

Prevention for blocked tear duct

To reduce your take a chance of developing a blocked tear duct later in life, become prompt handling of middle inflammation or infections. Follow these tips to avoid eye infections in the get-go place:

• Launder your hands thoroughly and often.
• Try not to rub your optics.
• Replace your eyeliner and mascara regularly. Never share these cosmetics with others.
• If you habiliment contact lenses, keep them make clean co-ordinate to recommendations provided by the manufacturer and your eye care specialist.

Blocked tear duct symptoms

If the tear passageways go blocked, tears cannot drain properly and may overflow from the eyelids onto the face as if you lot were crying. The symptoms of a blocked tear duct may become worse afterwards a cold or sinus infection. Also, symptoms may be more noticeable later on exposure to cold, wind or sunlight. In addition to excessive tearing you may also experience blurred vision, mucous discharge, eye irritation, and painful swelling in the inner corner of the eyelids. A thorough examination by an ophthalmic plastic surgeon can determine the crusade of tearing and recommended handling.

When tear ducts are blocked, trapped bacteria in the nasolacrimal sac can lead to infection (chosen dacryocystitis). Symptoms of infection include:

• Inflammation (swelling), tenderness and redness of the inside corner of the eye or around the centre and nose
• Recurrent eye infections or inflammation (pinkish centre)
• Heart fungus discharge
• Crusty eyelashes
• Blurred vision
• Blood-tinged tears
• Fever

Blocked tear duct diagnosis

To diagnosis your condition, your doctor talks with you lot about your symptoms, examines your eyes and does a few tests. He or she will also examine the inside of your olfactory organ to decide if any structural disorders of your nasal passages are causing an obstruction. If your doctor suspects a blocked tear duct, he or she may have y'all undergo other tests to find the location of the blockage.

Your heart doctor will also use certain tests to examine the tear drainage system for blockage. A special fluid is flushed into the affected tear duct opening and, if the fluid cannot exist tasted in the throat, a blocked tear duct is diagnosed.

Other tests may include an X-ray or CT scan of the tear duct area (chosen a dacryocystogram).

Tests used to diagnose a blocked tear duct include:

• Tear drainage test. This examination measures how quickly your tears are draining. 1 drib of a special dye is placed on the surface of each eye. Y'all may have a blocked tear duct if subsequently v minutes nigh of the dye is still on the surface of your eye.
• Irrigation and probing. Your doctor may affluent a saline solution through your tear drainage arrangement to check how well it's draining. Or he or she may insert a slender musical instrument (probe) through the tiny drainage holes at the corner of your lid (puncta) to check for blockages. In some cases this probing may even set up the problem.
• Center imaging tests. For these procedures, a contrast dye is passed from the puncta in the corner of your lid through your tear drainage arrangement. So 10-ray, computerized tomography (CT) or magnetic resonance imaging (MRI) images are taken to detect the location and cause of the blockage.

Blocked tear duct handling

Depending on your symptoms and their severity, your specialist will suggest an appropriate course. In mild cases, a treatment of warm compresses and antibiotics may be recommended. In more astringent cases, surgical intervention to bypass the tear duct obstacle (dacryocystorhinostomy surgery) may be recommended. A dacryocystorhinostomy is performed past creating a new tear passageway from the lacrimal sac to the olfactory organ, bypassing the obstruction. A modest silicone tube called a stent may temporarily be placed in the new passageway to keep information technology open up during the healing process. In a small percentage of cases, the obstacle is between the puncta and the lacrimal sac. In these cases, in addition to the dacryocystorhinostomy process, the surgeon will insert a tiny artificial tear bleed called a Jones Tube. A Jones Tube is made of Pyrex glass and allows tears to drain directly from the eye to the lacrimal sac.

Dacryocystorhinostomy surgery is commonly performed equally an outpatient process. Patients usually have some bruising and swelling on the side of the nose that subsides in one to 2 weeks. In general, surgery has a greater than 90% success rate and about patients feel a resolution of their tearing and discharge problems once surgery and recovery are completed.

Blocked tear duct in adults treatment

In most cases of blocked tear ducts after a facial injury, the drainage system starts working over again on its own a few months after the injury, and no additional treatment is necessary. Your ophthalmologist (center doctor) may recommend waiting a few months after the injury before considering surgery to open the blocked tear duct.

Blocked tear duct babe handling

Many babies with congenital blocked tear duct improve on their own in the first several months of life, subsequently the drainage arrangement matures or the actress membrane involving the nasolacrimal duct opens up. In some cases, your ophthalmologist (eye medico) may recommend that you use a special massage technique to help open upwardly the membrane covering the lower opening into your babe's nose. He or she will demonstrate how to correctly do this massage.

The purpose of massage is to put pressure on the lacrimal sac to pop open the membrane at the bottom of the tear duct. This is most easily accomplished by placing your hands on each side of the baby'southward face with your index finger(s) between the inner corner of the eye and the side of the olfactory organ, pressing in and down over the lacrimal sac for a few seconds. The massage should be done once in the morn and once in the evening, and each massage should be 10 strokes each. It is best to do the massage during a diaper change.

Dilation, probing and flushing

For infants and toddlers whose blocked tear ducts aren't opening on their own, or for adults who have a partially blocked duct or a partial narrowing of the puncta, a technique using dilation, probing and irrigation may be used. An musical instrument is used to enlarge (dilate) the punctal openings and a narrow probe is guided through the puncta, into the tear drainage system, and then through the nasal opening and removed. The tear drainage organisation is flushed with a saline solution to clear out whatever residual blockage.

Balloon catheter dilation

A balloon catheter dilation procedure opens tear drainage passages that are narrowed or blocked by scarring or inflammation. General anesthesia is used. A narrow catheter (tube) with a deflated balloon on the tip is guided through the lower nasolacrimal duct. The md and then uses a pump to inflate and deflate the balloon along the drainage system.

Stenting or intubation

With a procedure called stenting or intubation, tiny tubes are used to open up blockages and narrowing inside the tear drainage system. Again, general anesthesia is usually used. Your ophthalmologist (heart doctor) threads a very thin tube through 1 or both puncta in the corner of your heart, all the manner through the tear drainage system and out through your nose. A tiny loop of tubing remains at the corner of your eye, just while it is visible, information technology'southward ordinarily not bothersome. These tubes are generally left in for 3 to iv months, and then removed.

Blocked tear duct surgery

Surgery is commonly the preferred option for people who develop blocked tear ducts. It is also constructive in babies and toddlers with congenital blocked tear ducts, though usually an option only after other treatments have been tried.

Dacryocystorhinostomy is the surgical procedure usually used to treat most cases of blocked tear ducts in adults and rarely in children. This technique creates a new route for tears to drain out through your nose normally again by developing a new connectedness between your lacrimal sac and your olfactory organ. First you lot're given a full general coldhearted, or a local anesthetic if it's performed as an outpatient process. This new route bypasses the duct that empties into your nose (nasolacrimal duct), which is typically the blockage site. Stents or intubation typically are placed in the new route while it heals, and and then removed three or four months subsequently surgery. The steps in this procedure will vary depending on your particular tear duct blockage.

Depending on the type of blockage, your surgeon may recommend creating an entirely new route from the within corner of your eyes (puncta) to your nose, bypassing the tear drainage system altogether. This reconstruction of your unabridged tear drainage system is called conjunctivodacryocystorhinostomy.

To prevent postoperative infection and inflammation, you will need to use a nasal decongestant spray and eye drops. After about three to six months, your ophthalmologist (eye doctor) will remove any stents that were put in place to go along the new channel open while healing.

If a tumor is causing your blocked tear duct, surgery may be performed to remove the tumor, or other treatments may be used to compress it.

The steps in this process vary, depending on the exact location and extent of your blockage, as well as your surgeon'due south experience and preferences.

• External. With external dacryocystorhinostomy, your surgeon makes an incision on the side of your olfactory organ, well-nigh where the lacrimal sac is located. After connecting the lacrimal sac to your nasal crenel and placing a stent in the new passageway, the surgeon closes upwards the skin incision with a few stitches.
• Endoscopic or endonasal. With this method, your surgeon uses a microscopic camera and other tiny instruments inserted through the nasal opening to your duct system. This method requires no incision so leaves no scar. But the success rates aren't every bit high as with the external process.

Following surgery you'll use a nasal decongestant spray and eyedrops to preclude infection and reduce inflammation. Later three to six months, yous'll render to your doctor's part for removal of any stents used to keep the new channel open during the healing process.

Surgery side effects

The principal risks of tear duct surgery are recurrence of the blockage (in about ten percent of cases), infection (which is extremely rare), and blood from the middle or the nose. The bleeding ordinarily subsides in a few hours from surgery and is only a few drops of claret mixing with the tears.
