What Causes Watery Eyes?
Watery eyes, also known as epiphora, can be a frustrating and persistent condition, affecting both comfort and appearance. The tears produced by our eyes serve an essential role in keeping the surface of the eye moist, clean, and protected. However, when the normal balance of tear production and drainage is disrupted, excessive tearing can occur, leading to various bothersome symptoms. Watery eyes may arise from two primary causes: an overproduction of tears or an obstruction in the tear drainage system.
Overproduction of Tears
One of the main causes of watery eyes is an overproduction of tears. The eyes may produce excess tears in response to irritation, infection, or inflammation. Common causes of overproduction include:
- Eye Irritation: Environmental factors, such as wind, smoke, or dry air, can irritate the eyes, prompting them to produce more tears in an attempt to protect and lubricate the surface.
- Blepharitis: This condition, characterised by inflammation of the eyelid margins, can lead to increased tear production due to irritation of the eye’s surface.
- Allergic Reactions: Allergies, whether seasonal or perennial, can cause inflammation in the eyes and lead to excess tearing. Common allergens include pollen, dust, pet dander, or certain chemicals found in cosmetics or skincare products.
When tear production becomes excessive, the tears may overwhelm the natural drainage system, leading to the sensation of watery eyes, which can be accompanied by discomfort, blurred vision, and a feeling of grittiness in the eyes.
Blockage of the Tear Drainage System
Alternatively, blockage or dysfunction of the tear drainage system can also result in watery eyes. The tear drainage system is responsible for collecting and draining excess tears away from the eye, through tiny openings called puncta, into the tear ducts, and ultimately into the nose. If any part of this drainage system becomes blocked, tears cannot drain properly, causing them to accumulate and spill over onto the face.
The blockage may occur in different parts of the tear drainage system, and the severity of the condition depends on the location of the obstruction:
- Punctal Blockage: The puncta are the tiny openings located on the inner corner of the eyelids, through which tears drain. If these openings become blocked or narrowed, it can lead to a buildup of tears. This is typically treated with a minor procedure known as punctoplasty, which can be performed under local anaesthesia to open or widen the punctal opening, restoring proper tear drainage.
- Nasolacrimal Duct Obstruction: If the blockage occurs deeper in the system, in the nasolacrimal duct (which runs from the eye into the nose), more complex intervention may be required. A common procedure to address this is Dacryo-Cysto-Rhinostomy (DCR), a surgery performed under general anaesthesia to bypass the blocked duct and restore normal tear drainage. During a DCR procedure, a new passage is created between the tear sac and the nasal cavity, allowing tears to drain properly once again.
Symptoms and Impact of Watery Eyes
Excessive tearing can lead to several symptoms and challenges, including:
- Blurred Vision: Constant tearing may blur the vision, making everyday tasks like reading or driving difficult.
- Skin Irritation: Tears that overflow onto the skin can cause irritation, redness, and soreness around the eyes, particularly in the delicate skin beneath the eyes.
- Frequent Infections: Blocked tear ducts can create an environment suitable for bacterial growth, leading to recurrent infections or inflammation in the tear drainage system, such as dacryocystitis.
- Difficulty with Makeup: For those who wear makeup, excessive tearing can lead to smudging and make it difficult to maintain a neat, polished appearance.
- Social Embarrassment: Constant watery eyes may also result in feelings of self-consciousness or social embarrassment, as the condition may be perceived as unsightly or uncomfortable by others.
Treatment Options for Watery Eyes
At Maldon Eye Clinic, we offer a comprehensive range of treatment options for watery eyes, tailored to the underlying cause of the condition. Whether the cause is excessive tear production or a blockage in the tear drainage system, we work with patients to identify the most appropriate treatment approach.
Medical Treatments
If the watery eyes are due to excessive tear production from irritation or inflammation, our ophthalmologists may recommend:
- Antihistamines or Allergy Drops: If allergies are the primary cause, antihistamines or specific eye drops can help reduce inflammation and control tearing.
- Lubricating Eye Drops or Ointments: For conditions like blepharitis, lubricating eye drops or ointments may be prescribed to soothe irritation and reduce the need for excessive tear production.
- Lifestyle Adjustments: Our team may advise simple lifestyle changes, such as using a humidifier to alleviate dry air or taking breaks from digital screens to reduce eye strain.
Surgical Interventions
If the watery eyes are caused by blockage in the tear drainage system, surgical intervention may be necessary to restore normal tear flow:
- Punctoplasty: This minimally invasive procedure is performed under local anaesthesia and involves widening or unblocking the puncta to improve drainage of tears. It is often effective for patients with blockage in the initial part of the tear drainage system.
- Dacryo-Cysto-Rhinostomy (DCR): For more extensive blockages, particularly those involving the nasolacrimal duct, DCR surgery is the standard treatment. This procedure is performed under general anaesthesia and involves creating a bypass route for the tears to drain from the tear sac into the nose.
Both procedures are performed by our highly skilled ophthalmologist, who are committed to providing safe, effective solutions for restoring comfort and improving the quality of life for our patients.
