What causes a blocked tear duct in adults?

The most common cause in adults is primary acquired nasolacrimal duct obstruction (PANDO), a chronic inflammatory narrowing of the nasolacrimal duct that occurs with aging. Other causes include chronic sinus disease, previous nasal or facial surgery, trauma, tumors, and granulomatous conditions such as sarcoidosis.

Can a blocked tear duct be treated without surgery?

In adults, a complete nasolacrimal duct obstruction does not resolve with conservative measures alone. While antibiotic drops treat associated infections, the structural blockage requires surgical bypass (dacryocystorhinostomy). Partial obstructions may sometimes be managed with probing and stenting, though results are less predictable.

Is a blocked tear duct in a baby the same condition?

Congenital nasolacrimal duct obstruction is a separate condition caused by an imperforate membrane at the valve of Hasner. It affects up to 20 percent of newborns. Most cases resolve spontaneously within the first year of life. If not, a simple probing procedure is highly effective. Adult-onset obstruction has different causes and usually requires dacryocystorhinostomy.

How do I know if my tearing is from a blocked duct or dry eye?

Both conditions cause tearing, which can be confusing. Blocked-duct tearing is typically continuous, worse outdoors, and may be accompanied by mucous discharge or recurrent infections at the inner corner. Dry-eye tearing is usually intermittent, provoked by wind or screen use, and associated with burning and grittiness. A clinical examination with dye disappearance and irrigation tests can distinguish the two.

Tear Duct Obstruction — Diagnosis & Treatment

Kısa Yanıt

Nasolacrimal duct obstruction (blocked tear duct) prevents tears from draining normally from the eye into the nose. This leads to persistent tearing, mucous discharge, and recurrent infections of the lacrimal sac (dacryocystitis). In adults the obstruction is usually acquired and requires surgical treatment -- dacryocystorhinostomy (DCR) -- to create a new drainage pathway.

How Tear Drainage Works

Tears are produced by the lacrimal gland and spread across the eye surface with each blink. They then drain through the upper and lower puncta (tiny openings at the inner lid margin), into the canaliculi, the lacrimal sac, and finally through the nasolacrimal duct into the nose. A blockage at any point along this pathway disrupts tear flow and causes symptoms.

Causes

Primary acquired nasolacrimal duct obstruction (PANDO)

The most common cause in adults. Chronic low-grade inflammation leads to progressive fibrosis and narrowing of the nasolacrimal duct. It is more prevalent in middle-aged and older women.

Secondary causes

Chronic sinusitis or nasal polyps
Previous nasal, sinus, or facial surgery
Mid-face trauma or nasolacrimal fractures
Lacrimal sac or nasal tumors (rare but important to exclude)
Granulomatous diseases (sarcoidosis, granulomatosis with polyangiitis)
Systemic chemotherapy with certain agents (e.g., docetaxel, 5-fluorouracil)
Chronic dacryolith (stone within the lacrimal sac)

Congenital nasolacrimal duct obstruction

Found in newborns when the lower end of the nasolacrimal duct fails to canalize. Tearing and discharge begin soon after birth. Most cases resolve by age one; persistent cases are treated with probing, and rarely with more advanced procedures.

Symptoms

Persistent watery eyes (epiphora), often worse in cold or windy weather
Mucous or mucopurulent discharge at the inner corner of the eye
Crusting of the eyelashes on waking
Reflux of mucous when pressing on the lacrimal sac area
Recurrent episodes of acute lacrimal sac infection (dacryocystitis) with swelling, redness, and pain below the inner corner
Blurred vision due to the tear film meniscus

Diagnosis

Fluorescein dye disappearance test: A drop of fluorescein is placed in the eye; delayed clearance indicates impaired drainage.
Lacrimal irrigation: Saline is flushed through the punctum. In complete obstruction, fluid regurgitates rather than reaching the nose.
Dacryocystography (DCG) or CT-DCG: Contrast imaging to identify the exact site and extent of the blockage.
Nasal endoscopy: Assesses the nasal anatomy and rules out intranasal pathology before planning surgery.

Treatment Options

Conservative measures

In partial obstructions, warm compresses, lacrimal sac massage, and topical antibiotics may offer symptom relief. These do not resolve a complete blockage but can manage symptoms while awaiting surgery.

Dacryocystorhinostomy (DCR)

The gold-standard surgical treatment for nasolacrimal duct obstruction. A new drainage pathway is created between the lacrimal sac and the nasal cavity, bypassing the blocked duct. DCR can be performed through an external (skin) incision or endonasally (through the nose). Success rates exceed 95 percent in experienced hands. See our dedicated DCR surgery page for full details.

Silicone stent intubation

Thin silicone tubes may be placed through the lacrimal system during DCR or as a standalone procedure for partial obstructions. The stents are typically removed after two to three months.

Recovery After DCR

First 24-48 hours

Mild swelling and bruising around the inner corner of the eye. Nasal packing (if used) is removed within 24 hours. Avoid nose-blowing.

Week 1

Bruising begins to fade. Antibiotic and steroid nasal sprays are used as directed. Saline irrigation keeps the nasal passage clean.

Weeks 2-4

Tearing improves significantly. Most patients return to work within one to two weeks. External sutures (if applicable) are removed around day 7.

Months 2-3

Silicone stents are removed in the office if placed. Final assessment of tear drainage function is performed.

Ne Zaman Acil Doktora Başvurmalı?

•Sudden painful swelling, redness, and warmth below the inner corner of the eye (acute dacryocystitis -- may require urgent antibiotics or drainage)
•Fever accompanying lacrimal sac swelling (possible preseptal or orbital cellulitis)
•Persistent bloody tears, especially in patients over 50 (must exclude a lacrimal sac tumor)
•Progressive tearing associated with nasal obstruction (may indicate a nasal mass)
•A hard, non-tender mass at the medial canthus that does not deflate with pressure

Acute dacryocystitis can progress to orbital cellulitis if untreated. Seek medical attention promptly.

Clinical Note
Not all tearing is caused by a blocked tear duct. A thorough assessment of the lacrimal system -- from the puncta to the nasolacrimal duct, combined with nasal endoscopy -- is essential before recommending surgery. When obstruction is confirmed, DCR remains the most reliable solution. I also emphasize the importance of excluding a lacrimal sac mass in any patient with a firm lump at the inner corner of the eye or blood-tinged tears, as lacrimal sac tumors, though rare, can mimic simple obstruction.
