Tear Duct Evaluation: What Does the Specialist Examine?

Q: When is a tear duct evaluation recommended?

The most common reason for evaluation is persistent tearing. Although excessive tearing may occur because of dry eye, allergies, or irritation, in other patients the problem is related to inadequate drainage. A tear duct evaluation may be helpful when there is: - Constant tearing in one or both eyes - A persistent watery sensation - Recurrent discharge - Repeated infections near the inner corner of the eye - Swelling near the side of the nose - Blurred vision caused by excessive tearing - Symptoms following surgery or trauma Abnormal eyelid position can also prevent tears from entering the drainage system normally.

Q: What does the specialist examine?

A tear duct evaluation involves more than confirming that the eye is watery. The examination may include: - Eyelid position - Tear drainage openings - Ocular surface - Dry eye or inflammation - Presence of discharge - Lacrimal sac area - Function of the tear drainage system It is also important to know when the problem began, whether it affects one or both eyes, and whether there is a history of infection, trauma, nasal surgery, or eyelid surgery.

Q: What symptoms may suggest a tear duct obstruction?

In addition to constant tearing, patients may experience: - Frequent need to wipe the eye - Discharge or crusting - Irritation of the eyelid skin - Recurrent conjunctivitis - Intermittent blurred vision - Pain or swelling near the side of the nose Pain, redness, or swelling over the lacrimal sac, especially when associated with discharge or fever, may indicate an infection and should be evaluated promptly.

Q: What should you expect during the consultation?

The consultation is focused on determining why tearing or discharge is occurring and whether the tear drainage system is functioning properly. Depending on the case, the examination may include an eye evaluation, inspection of the tear drainage openings, and drainage testing. In many patients, this makes it possible to determine during the first visit whether the problem is caused by an obstruction, ocular surface disease, or an eyelid abnormality. If you have persistent tearing, recurrent discharge, or swelling near the inner corner of the eye, a tear duct evaluation can help identify the cause and determine the most appropriate treatment. In Dr. Andrés Lozano’s practice, the evaluation combines ophthalmology and oculoplastic surgery to assess the tear drainage system, eyelids, and ocular surface together.

Constant tearing, a persistently watery eye, or recurrent discharge is not always caused by simple irritation. In many cases, a tear duct evaluation can help determine why tears are not draining properly and which treatment may be appropriate.

The tear drainage system carries tears from the surface of the eye into the nose. When there is narrowing, blockage, or an abnormal eyelid position, patients may develop excessive tearing, discharge, blurred vision, or recurrent infections.

When is a tear duct evaluation recommended?

The most common reason for evaluation is persistent tearing.

Although excessive tearing may occur because of dry eye, allergies, or irritation, in other patients the problem is related to inadequate drainage.

A tear duct evaluation may be helpful when there is:

Constant tearing in one or both eyes
A persistent watery sensation
Recurrent discharge
Repeated infections near the inner corner of the eye
Swelling near the side of the nose
Blurred vision caused by excessive tearing
Symptoms following surgery or trauma

Abnormal eyelid position can also prevent tears from entering the drainage system normally.

What does the specialist examine?

A tear duct evaluation involves more than confirming that the eye is watery.

The examination may include:

Eyelid position
Tear drainage openings
Ocular surface
Dry eye or inflammation
Presence of discharge
Lacrimal sac area
Function of the tear drainage system

It is also important to know when the problem began, whether it affects one or both eyes, and whether there is a history of infection, trauma, nasal surgery, or eyelid surgery.

How is tear drainage tested?

Depending on the examination findings, specific tests may be performed to determine whether the tear drainage system is open and where a blockage may be located.

One of the most commonly used tests is tear duct irrigation. Sterile fluid is gently introduced through the tear drainage opening to determine whether it passes into the nose or meets resistance.

This can help identify:

Narrowing of the tear drainage opening
Partial obstruction
Complete obstruction
Functional drainage problems

In some cases, imaging studies may also be necessary, particularly when there is a history of trauma or surgery, a palpable mass, or concern for a deeper abnormality.

Not all tearing means a blocked tear duct

Although it may seem contradictory, dry eye can also cause excessive tearing.

When the ocular surface becomes irritated, the eye may respond by producing a large amount of reflex tears that do not lubricate effectively.

Other causes of tearing may include:

Allergies
Ocular inflammation
Abnormal eyelid position
Eyelid laxity
Ectropion
Narrow tear drainage openings

For this reason, evaluation should include the tear drainage system, eyelids, and ocular surface.

What symptoms may suggest a tear duct obstruction?

In addition to constant tearing, patients may experience:

Frequent need to wipe the eye
Discharge or crusting
Irritation of the eyelid skin
Recurrent conjunctivitis
Intermittent blurred vision
Pain or swelling near the side of the nose

Pain, redness, or swelling over the lacrimal sac, especially when associated with discharge or fever, may indicate an infection and should be evaluated promptly.

How is treatment determined?

Treatment depends on the underlying cause.

When tearing is related to dry eye, inflammation, or allergies, targeted medical treatment may be sufficient.

If the tear drainage opening is narrowed, a procedure to improve its opening may be considered.

When a deeper obstruction is present, treatment may involve probing, silicone tube placement, or surgery to create a new drainage pathway, depending on the location and type of blockage.

The decision should be based on the examination findings rather than tearing alone.

Why is a complete evaluation important?

The tear drainage system works together with the eyelids and ocular surface. For this reason, all of these structures should be considered during the evaluation.

In a practice that combines ophthalmology and oculoplastic surgery, both tear drainage and eyelid or ocular surface abnormalities can be assessed together.

This approach can help avoid repeated treatments that temporarily improve symptoms without correcting the underlying cause.
