Key Takeaways

  • A blocked tear duct happens when the drainage system that carries tears from the eye to the nose becomes narrowed or obstructed, causing tears to overflow.
  • In adults, common causes include age-related narrowing, chronic infections or inflammation, injury, certain medications, and, less commonly, tumors.
  • Watery eyes are the most recognizable symptom, but a blocked tear duct can also cause crusting, mucus discharge, recurring infections, and swelling near the inner corner of the eye.
  • Most adult blockages do not resolve on their own and benefit from professional evaluation, especially if symptoms persist or come with pain or pus.
  • Conestoga Eye offers specialized tearing and oculoplastic care in Lancaster and Hershey, PA, including procedures for blocked tear ducts, and patients can schedule a consultation for an accurate diagnosis and treatment plan.

What Is a Blocked Tear Duct?

A blocked tear duct, medically known as nasolacrimal duct obstruction, occurs when the small drainage passages between the eye and the nose become partially or fully blocked. Normally, tears drain through tiny openings at the inner corner of each eyelid, down through the tear sac, and into the nose. When this drainage system is obstructed, tears have nowhere to go and overflow onto the cheek, causing what feels like constant watery eyes.

While blocked tear ducts are common in newborns and usually resolve without treatment, the same is not true in adults. In adults, the blockage often points to an underlying issue that needs to be evaluated and managed.

How the Tear Drainage System Normally Works

Understanding the tear drainage system makes blocked tear duct symptoms much easier to recognize. The system works like this:

  • Tears are produced by the lacrimal glands above each eye.
  • With every blink, tears spread across the eye to keep it lubricated and protected.
  • Tears drain into two small openings (called puncta) at the inner corner of the upper and lower eyelids.
  • From there, tears flow through small channels (canaliculi) into the lacrimal sac, located near the side of the nose.
  • The lacrimal sac empties into the nasolacrimal duct, which drains tears into the nasal cavity.

According to the Cleveland Clinic, a blockage can develop anywhere along this pathway, from the small openings on the eyelids all the way down to the nose. When any part of this system narrows or becomes obstructed, tears back up and the eye starts to water excessively.

Common Causes of Tear Duct Blockage in Adults

Unlike in infants, blocked tear ducts in adults typically have a specific underlying cause. The most common include:

Age-Related Narrowing

The most frequent cause of blocked tear ducts in adults is gradual narrowing of the drainage passages with age. The tissue lining the tear ducts can thicken or scar over time, slowly restricting tear flow. This type of blockage tends to develop in middle age or later.

Chronic Infections and Inflammation

Repeated infections of the eye, eyelids, or nasal sinuses can lead to inflammation that narrows the tear ducts. Conditions such as chronic sinusitis, conjunctivitis, and inflammation of the tear sac (dacryocystitis) can all contribute. The Mayo Clinic notes that recurring infections are both a possible cause and a possible consequence of a blocked tear duct, which is why early evaluation matters.

Injury or Trauma

Trauma to the face, especially around the nose or eye, can damage the tear drainage system. Fractures of the nasal bones, scarring after facial surgery, or even smaller injuries can disrupt the passages and lead to chronic tearing.

Tumors and Other Less Common Causes

Although less common, growths in or near the tear drainage system can press on the ducts and block tear flow. This is one reason persistent watery eyes in an adult should always be evaluated by a specialist rather than assumed to be a minor issue.

Eye Drops, Medications, and Other Risk Factors

Long-term use of certain eye drops, especially some glaucoma medications, can contribute to scarring of the tear ducts over time. Other potential risk factors include:

  • Previous radiation treatment to the face
  • Chemotherapy drugs that can cause inflammation
  • Nasal polyps or other structural nasal issues
  • A history of facial or nasal surgery
  • Inflammatory conditions affecting the eyes or sinuses

Symptoms That May Accompany Excessive Tearing

While watery eyes are the hallmark symptom of a blocked tear duct, adults may also notice:

  • Crusting along the eyelid, especially in the morning
  • Yellowish or sticky mucus discharge
  • Recurring eye infections that keep coming back
  • Blurred vision caused by excessive tears on the eye surface
  • Swelling or tenderness near the inner corner of the eye
  • Redness or irritation of the eye or eyelid
  • A noticeable lump or bulge at the side of the nose (a sign of a tear sac infection)

Symptoms may be constant, or they may flare up during certain activities, like going outside in cold or windy weather, that naturally increase tear production.

When Infections or Inflammation Become a Concern

A blocked tear duct that is not addressed can become a setup for repeated infections. When tears cannot drain properly, the stagnant fluid becomes a breeding ground for bacteria. This can lead to a condition called dacryocystitis, an infection of the tear sac.

Signs of an active tear duct infection include:

  • Pain and tenderness over the inner corner of the eye, near the side of the nose
  • Swelling or a visible bump in that area
  • Pus or thick discharge coming from the eye, especially when pressure is applied near the tear sac
  • Fever in more serious cases

Tear duct infections require prompt medical attention. Antibiotic treatment is usually the first step, but recurring infections often signal that the underlying blockage needs to be addressed surgically to provide lasting relief.

Signs It's Time to Seek Professional Treatment

Many adults try to manage watery eyes on their own, assuming the problem will resolve. While occasional tearing from allergies, irritation, or wind is normal, persistent symptoms call for professional evaluation. Consider scheduling an appointment if you experience:

  • Watery eyes that last for more than a few weeks
  • Recurring eye infections
  • Crusting, discharge, or swelling near the inner corner of the eye
  • Tearing that interferes with daily activities like reading, driving, or working
  • Pain or tenderness around the eye
  • Vision changes related to constant tearing

A specialist can perform a thorough evaluation, identify the location and cause of the blockage, and recommend the right treatment.

Treatment Options for Blocked Tear Ducts

Treatment depends on the cause and severity of the blockage. Options may include:

ApproachWhat It InvolvesBest For
Warm compresses and massageAt-home care to encourage drainageMild or partial blockages
Antibiotic eye drops or ointmentsTreats active infection or inflammationBacterial infection with blockage
Probing and irrigationA thin probe gently opens the drainage passagesSelected partial blockages
Balloon dilationA tiny balloon expands the narrowed ductCertain partial blockages
Stent placementA small tube keeps the duct open during healingSome recurring or chronic cases
Dacryocystorhinostomy (DCR)Surgical procedure that creates a new drainage pathwayPersistent or complete blockages

For many adults with persistent blockages, the most effective long-term solution is a dacryocystorhinostomy. Dr. David Silbert performs this surgery endoscopically through the nose so there are no visible facial incisions. He is one of very few surgeons in the nation who apply this unique and non-invasive technique.

Frequently Asked Questions

What causes blocked tear duct problems in adults?

The most common causes of blocked tear ducts in adults are age-related narrowing of the drainage passages, chronic infections or inflammation, facial injuries, long-term use of certain eye drops, and, less commonly, tumors near the tear drainage system. Because adults rarely outgrow these blockages the way infants do, professional evaluation is usually recommended.

What are the most common blocked tear duct symptoms?

The most recognizable symptom is constant watery eyes that overflow onto the cheek. Other symptoms include crusting along the eyelid, mucus discharge, recurring eye infections, swelling or tenderness near the inner corner of the eye, and blurred vision caused by excess tears on the eye surface.

Are there watery eye causes I can manage at home?

Mild tearing from allergies, dry eye, eyelash irritation, or temporary inflammation can often be managed at home with warm compresses, artificial tears, and good eyelid hygiene. However, persistent tearing that lasts more than a few weeks, or that comes with discharge, swelling, or recurring infections, should be evaluated by an eye care professional.

How is tear duct blockage diagnosed?

An eye specialist can diagnose a tear duct blockage through an exam that includes evaluating tear production, examining the eyelids and drainage openings, and sometimes performing a simple in-office test where saline is gently flushed through the tear duct to check flow. Imaging may be used in select cases.
