Canaliculitis
Recognizing the Signs of Canaliculitis
Your tear drainage system includes two small openings on the inner edge of your upper and lower eyelids. These openings lead to narrow tubes called canaliculi that carry tears away from your eye. When bacteria or fungi infect these tubes, often aided by trapped foreign material, the lining becomes swollen and fills with debris.
This condition is called canaliculitis. While it can affect people of any age, it is more common in middle-aged and older adults, with a slight female predominance reported. The infection usually develops slowly over weeks or months, which is why early symptoms are sometimes overlooked.
The most common sign of canaliculitis is constant tearing from one eye. You may also notice a sticky yellow or white discharge that keeps coming back even after you clean your eye. The skin around the inner corner of your eyelid often looks red and puffy. These yellow concretions are characteristic of canaliculitis.
- Persistent tearing that does not improve with time
- Thick discharge from the inner corner of your eye
- Swelling and tenderness near the tear duct opening
- Crusting on your eyelashes, especially in the morning
- A sensation of pressure or fullness in your eyelid
- A pouting punctum (the tear duct opening looks swollen and turned outward)
- Yellow, gritty granules that can be expressed from the punctum when the inner eyelid is pressed
Most cases of canaliculitis develop gradually, but certain warning signs require prompt medical care. If you experience sudden vision changes, severe eye pain, or rapidly spreading redness, seek urgent ophthalmic care. These symptoms can indicate spread to the lacrimal sac or orbit.
Go to urgent care or the emergency department if you develop fever with a painful swelling below the inner corner of the eye (possible dacryocystitis), worsening eyelid redness with severe pain, double vision, painful or limited eye movements, bulging of the eye, or decreased vision. You should also seek urgent care if you notice pus draining from your eyelid or see a hard lump forming near your tear duct. Early treatment can prevent complications and preserve your normal tear drainage function.
Why Canaliculitis Develops
Canaliculitis usually happens when bacteria build up inside the canaliculus. The most common organism is Actinomyces, and infections are often polymicrobial with anaerobic bacteria. Actinomyces forms tiny, hard clumps called concretions that adhere to the canalicular wall.
Fungal canaliculitis is uncommon and tends to occur in specific settings such as immunosuppression; Candida and Aspergillus are the usual fungi. The infection tends to persist because the narrow tubes trap debris and make it hard for your natural defenses to clear the germs.
Sometimes canaliculitis develops after insertion of punctal plugs. These tiny devices are placed in the tear duct openings to help keep tears on the eye surface. While they work well for many people with dry eyes, they can occasionally shift position or allow bacteria to collect around them.
- Punctal plugs that have been in place for a long time
- Eyelash fragments that migrate into the tear duct
- Makeup or debris lodged in the canaliculus
- Dust or small particles that enter the drainage system
If a punctal or intracanalicular plug is present, definitive treatment requires removal. Intracanalicular plugs often need surgical retrieval and, when their location is uncertain, may require imaging or lacrimal endoscopy.
Certain health problems can make you more likely to develop canaliculitis. Chronic eye infections, frequent conjunctivitis, or ongoing inflammation around your eyelids create an environment where germs thrive. Conditions that affect your immune system may also reduce your ability to fight off infections in the tear ducts.
We also see higher rates of canaliculitis with chronic lid margin disease and, in some cases, long-term topical medications that alter lid flora. Higher rates also occur in patients who have had previous eye surgery or experience blocked tear ducts. Age-related changes in tear duct anatomy can contribute to the problem as well. If you have diabetes or other chronic illnesses, you may face an elevated risk.
How Your Eye Doctor Diagnoses Canaliculitis
During your appointment, we will carefully examine the inner corners of your eyelids using magnification. We look for redness, swelling, and any visible discharge from the punctal openings. The affected area is often tender to gentle touch, and the surrounding skin may appear irritated. A characteristic finding is a pouting punctum with discharge expressed on gentle pressure.
We also check how your tears are draining by observing whether fluid pools on your eye surface. By pressing lightly on the eyelid near the tear duct, we can sometimes see thick material ooze from the punctal opening. This finding strongly suggests canaliculitis and helps us plan the best approach to treatment.
To confirm the diagnosis, we may gently squeeze the canaliculus to express any discharge or concretions. The material that comes out often has a distinctive appearance, ranging from white or yellow paste to small, gritty particles. This substance contains the germs causing your infection.
- Collecting a sample of the discharge for laboratory testing
- Identifying the specific bacteria or fungi present
- Determining which medications will be most effective
- Ruling out other conditions that mimic canaliculitis
- Requesting Gram stain and special processing for Actinomyces; histopathology of concretions can be more sensitive than standard culture
Standard cultures can be falsely negative without specific techniques.
In some cases, we recommend special tests to understand the full extent of the infection. A tear duct irrigation test helps us determine whether the drainage system is blocked and how well fluid can pass through. We may perform dilation, probing, and irrigation, and in select cases lacrimal endoscopy.
Imaging such as dacryocystography, ultrasound, or CT is reserved for atypical cases, complications, or when a retained intracanalicular plug is suspected. If your symptoms are severe or do not match the typical pattern, these additional tests ensure we have a complete picture before starting treatment. Blood tests are rarely needed but can be helpful if we suspect an underlying immune problem.
Your doctor may consider dacryocystitis, chronic conjunctivitis, blepharitis, punctal stenosis, and chalazion. Dacryocystitis typically causes a tender swelling below the inner corner of the eye over the lacrimal sac, often with fever, and needs urgent treatment.
Treatment Approaches for Canaliculitis
Conservative measures by themselves rarely resolve canaliculitis because concretions remain in the canaliculus; they are best used as short-term adjuncts while planning definitive care. For mild cases caught early, we often begin with warm compresses and massage of the affected area. Applying gentle heat several times a day can help soften any blockages and encourage drainage. We may also recommend cleaning your eyelid margins to reduce surface bacteria.
Antibiotic eye drops alone usually do not cure canaliculitis because the infection is deep within the tube. However, we may prescribe them if you also have conjunctivitis or surface inflammation. Conservative care works best when combined with close monitoring to ensure the infection does not worsen.
Once we identify the organisms, we prescribe targeted medications. Antibiotics are adjuncts to mechanical removal and are most effective after curettage or canaliculotomy. For Actinomyces, a penicillin-class antibiotic is often used; for penicillin allergy, alternatives such as doxycycline may be considered. Duration is tailored to response, commonly 1 to 2 weeks after the procedure, and longer for complicated cases.
- Oral antibiotics chosen based on culture results
- Antifungal medications for yeast or mold infections
- Topical antibiotic ointments to support healing
- Regular follow-up to monitor response to treatment
- Systemic therapy is adjunctive to mechanical debridement rather than a standalone cure
Many patients need a minor in-office procedure to physically remove the infected material and concretions. We use a tiny instrument to open the punctal opening slightly, then flush the canaliculus with antibiotic solution. Irrigation alone may not remove adherent concretions.
In addition to irrigation, we may perform curettage, which involves gently scraping the tube walls to remove stubborn concretions. The procedure is done with local anesthetic to keep you comfortable. A canaliculotomy, which opens the canaliculus along a short segment to allow thorough curettage, often provides the highest cure rates. A silicone stent may be placed to reduce scarring if there is significant narrowing. Combining this procedure with oral medication gives the best chance of clearing the infection. Possible risks include bleeding, scarring, canalicular stenosis, recurrence, and need for additional procedures.
When canaliculitis does not respond to medication and irrigation, surgery may be necessary. The most common approach is canaliculotomy, where we make a small opening in the tube to access and remove all infected tissue. This allows direct visualization and thorough cleaning of the affected area. In select cases with sac or nasolacrimal duct involvement, dacryocystorhinostomy may be considered.
In rare situations where the canaliculus is severely damaged, we may recommend reconstruction or placement of a temporary stent to keep the tube open while it heals. Silicone intubation is commonly used when there is significant inflammation or narrowing to reduce restenosis risk. These procedures are performed with great care to preserve your tear drainage function. We discuss all surgical options thoroughly with you and explain what to expect during recovery.
Caring for Your Eyes During and After Treatment
While you are being treated for canaliculitis, keeping the affected eye clean is essential. Use a warm, damp washcloth to gently wipe away any discharge several times each day. Wash your hands thoroughly before and after touching your eye to prevent spreading infection.
- Apply warm compresses for ten minutes three to four times daily
- Take all prescribed medications exactly as directed
- Avoid rubbing or pressing hard on the infected area
- Remove eye makeup until the infection has cleared
- Replace eye makeup and applicators that may be contaminated
- Do not try to probe the punctum or squeeze material from the duct yourself
- Avoid over-the-counter redness relievers unless advised by your doctor
Following canalicular irrigation or curettage, you may notice some mild discomfort and extra tearing for a day or two. This is a normal response as your tear duct adjusts to being cleaned out. Any swelling or redness should gradually improve over the next few days. If a silicone stent is placed, you may feel a soft tube; it is typically removed in 6 to 12 weeks.
We typically prescribe antibiotic drops or ointment to use after the procedure. You may also notice small amounts of blood-tinged discharge initially, which is not cause for alarm. If pain increases, discharge becomes thick and yellow again, or swelling worsens, contact our office right away. Most people return to normal activities within 24 hours of the procedure.
Regular follow-up visits are crucial to ensure your canaliculitis is fully resolved. We usually schedule your first check about one to two weeks after starting treatment. During these appointments, we examine the tear duct to confirm that the infection is clearing and drainage is improving. If a stent is placed, we will schedule removal and confirm that the canaliculus remains open.
Depending on your progress, you may need additional visits over the following weeks or months. We watch for any signs of recurrence and make sure your tear drainage system has returned to normal function. If symptoms return or do not fully resolve, we may need to adjust your medication or recommend further procedures.
Once your infection has cleared, maintaining good eyelid hygiene can help prevent future episodes. Gently clean your eyelid margins regularly, especially if you are prone to blepharitis or other lid conditions. If you have punctal plugs, we will monitor them closely and remove or replace them if needed.
- Practice daily eyelid hygiene with gentle cleansers
- Schedule regular eye exams to catch problems early
- Treat dry eye and other chronic conditions promptly
- Remove eye makeup thoroughly each night
- Report any new discharge or irritation right away
Frequently Asked Questions
Most patients begin to feel better within a few days of starting treatment, especially if we perform irrigation or curettage. However, complete resolution usually takes several weeks because oral antibiotics need time to fully eliminate the infection. Staying consistent with your medication and follow-up visits ensures the best outcome and reduces the chance of the infection coming back.
It is very unlikely for canaliculitis to resolve on its own. The concretions and infected debris remain trapped in the narrow canaliculus, creating a persistent source of inflammation. Without professional cleaning and appropriate medication, symptoms typically continue or worsen over time. Early treatment prevents damage to your tear drainage system.
Yes, we recommend stopping contact lens wear until your infection has completely cleared. Lenses can trap bacteria against your eye surface and interfere with healing. They may also become contaminated with discharge from the infected tear duct. Once we confirm that your canaliculitis is resolved, you can safely resume wearing contacts, but you should replace your old lenses and cases with fresh supplies.
Canaliculitis itself is not typically spread from person to person through casual contact. The infection lives deep within your tear duct rather than on the eye surface. However, good hygiene is still important because the bacteria or fungi involved could potentially spread to your other eye or contaminate shared items like towels and pillowcases. Wash your hands often and use your own personal linens during treatment.
Without treatment, the infection can permanently damage the delicate lining of your canaliculus, leading to scarring and chronic blockage. This may cause constant tearing, repeated infections, and difficulty draining tears properly. In rare cases, the infection can spread to surrounding tissues, creating a more serious abscess or cellulitis. Seeking care promptly protects your long-term eye health and comfort.
Recurrence can happen if concretions are not fully removed or a retained plug remains. Thorough curettage or canaliculotomy plus targeted antibiotics has a high success rate. Prompt evaluation of any new discharge or tearing helps prevent recurrence.
