A blocked tear duct is a common eye condition that can cause excessive watering, irritation, and discomfort. Although it is often associated with watery eyes rather than dry eyes, the two conditions can sometimes be linked. If your tears cannot drain properly, the surface of your eye may not receive the healthy tear film it needs, leading to irritation and symptoms similar to dry eye syndrome.

At Vision Care Clinic, our experienced eye specialists diagnose a wide range of eye conditions, including tear duct (lacrimal) issues and dry eye disease, to help patients find long-lasting relief and improve their eye comfort.

What Is a Blocked Tear Duct?

Your eyes constantly produce tears to keep the surface of the eye lubricated and protected. Normally, these tears drain away through tiny openings in the corners of your eyelids, known as tear ducts.

A blocked tear duct occurs when this drainage system becomes partially or completely blocked. Instead of draining away, tears build up on the surface of the eye, causing excessive watering and increasing the risk of irritation or infection.

Blocked tear ducts can affect both children and adults, although the causes may differ.

What Causes a Blocked Tear Duct?

There are several reasons why a tear duct may become blocked, including:

• Age-related narrowing of the tear drainage system
• Eye infections
• Chronic inflammation
• Injury to the eye or nose
• Previous eye or nasal surgery
• Swelling caused by allergies or sinus problems

In some cases, no obvious cause can be identified.

Symptoms of a Blocked Tear Duct

Symptoms can range from mild to more noticeable and may include:

• Constant watery eyes
• Tears running down the cheeks
• Redness around the inner corner of the eye
• Sticky discharge
• Swelling near the tear duct
• Recurrent eye infections
• Blurred vision caused by excessive tearing

Some patients also report soreness or irritation, particularly if the eye becomes inflamed.

Can a Blocked Tear Duct Cause Dry Eyes?

Although it may seem surprising, a blocked tear duct and dry eye syndrome can sometimes occur together.

Healthy tears contain a balance of water, oils, and mucus that help keep the eye comfortable. If tears are not draining properly, they may overflow without effectively coating the surface of the eye. In addition, some patients experience excessive watering as a response to irritation caused by dry eyes. These reflex tears do not provide the same lubrication as normal healthy tears, meaning your eyes can feel both watery and dry at the same time.

This is why a detailed eye examination is important to identify the underlying cause of your symptoms.

How Is It Diagnosed?

At Vision Care Clinic, your eye specialist will examine your eyes and tear drainage system to determine whether a blocked tear duct, dry eye syndrome, or another condition is responsible for your symptoms.

Your assessment may include:

• Examination of the eyelids and tear ducts
• Evaluation of your tear film
• Assessment of your overall eye health
• Discussion of your symptoms and medical history

An accurate diagnosis allows the most appropriate treatment to be recommended.

Treatment Options

Treatment depends on the cause of your symptoms. If your discomfort is related to dry eye disease, Vision Care Clinic offers personalised dry eye treatments to improve tear quality, reduce irritation, and restore comfort.

Depending on your diagnosis, treatment may include:

• Lubricating eye drops
• Eyelid hygiene advice
• Warm compresses
• Management of blepharitis or meibomian gland dysfunction

If a significant tear duct blockage is identified, you may be referred for further assessment and treatment if required.
