Watery Eyes (Epiphora) – A Complete Patient Guide

Overview

Epiphora (pronounced ee‑PHI‑fro‑ah) is the medical term for excessive tearing or “watery eyes.” It occurs when tears overflow onto the face rather than draining through the normal tear‑drainage system (the puncta, canaliculi, lacrimal sac, and nasolacrimal duct). While occasional tearing is normal—especially after crying, laughing, or exposure to wind—persistent epiphora can be a sign of an underlying ocular or systemic problem.

Anyone can develop watery eyes, but certain groups are more prone:

• Adults ≥ 50 years (age‑related lid‑margin changes and nasolacrimal obstruction are common)
• Children with congenital nasolacrimal duct obstruction (about 6–20 % of newborns)
• People with chronic eye‑surface disease (dry eye, allergic conjunctivitis, blepharitis)
• Contact‑lens wearers, especially those who use lenses for long periods

In the United States, epiphora accounts for roughly 5–10 % of all ophthalmology visits. Worldwide prevalence is harder to pin down, but large community‑based studies suggest a point prevalence of 1–2 % for clinically significant tearing.[^1]

Symptoms

The hallmark of epiphora is excessive tearing, but patients often notice a constellation of related signs:

• Constant or intermittent overflow of clear fluid onto the cheeks, especially after activities such as reading, driving, or exposure to wind.
• Blurred vision that improves after wiping away tears.
• Redness of the conjunctiva (the white part of the eye) due to irritation from constant moisture.
• Itching or burning sensation when the tear film is unstable.
• Crusting or discharge after sleeping, often mistaken for “sleepy eyes.”
• Foreign‑body feeling (grittiness) – especially if blockage forces tears onto the ocular surface.
• Swelling of the inner eyelid or visible blockage of the tiny puncta (the openings at the inner corner of the eyelids).
• Upper or lower eyelid drooping (ptosis) if the swelling or scar tissue involves the levator muscle.

Symptoms may be unilateral (one eye) or bilateral. When only one eye is affected, an obstructive cause (e.g., a nasal polyp pressing on the nasolacrimal duct) is more likely.

Causes and Risk Factors

Epiphora can be divided into two broad categories: excessive tear production and obstructed tear drainage.

Excessive Tear Production

• Allergic conjunctivitis: Histamine‑mediated inflammation stimulates lacrimal glands. (Mayo Clinic)
• Dry‑eye disease: Paradoxically, a deficient tear film triggers reflex tearing.
• Irritants: Smoke, wind, chlorine, cosmetics, or foreign bodies.
• Infections: Viral or bacterial conjunctivitis.
• Inflammatory eye conditions: Blepharitis, meibomian gland dysfunction, or rosacea of the eyelids.

Obstructed Tear Drainage

• Nasolacrimal duct obstruction (NLDO): Most common cause in adults; may be idiopathic or secondary to age‑related tissue laxity.
• Congenital nasolacrimal duct obstruction: Failure of the duct to open at birth; resolves spontaneously in ~90 % of infants by 12 months, but persists in a minority.
• Punctal stenosis or atresia: Scarring from chronic inflammation or surgery.
• Orbital tumors or cysts: Rare, but can compress the drainage pathway.
• Sinus disease: Chronic sinusitis or polyps that encroach on the nasolacrimal duct.
• Facial trauma or eyelid surgery: May scar the canaliculi.

Risk Factors

• Advancing age (tissue laxity, chronic eye conditions)
• History of allergic eye disease or chronic conjunctivitis
• Contact‑lens wear >8 hours/day
• Upper respiratory infections (temporary blockage due to inflammation)
• Systemic autoimmune diseases (e.g., Sjögren’s syndrome, which can cause both dry eye and reflex tearing)
• Smoking and exposure to air pollutants

Diagnosis

Diagnosing epiphora begins with a thorough history and eye examination. The goal is to determine whether the problem stems from overproduction or outflow obstruction.

History Taking

• Onset, duration, and pattern (continuous vs. episodic)
• Associated symptoms – itching, pain, visual changes, discharge
• Triggers (allergens, wind, reading, screen use)
• Past ocular surgeries or trauma
• Systemic illnesses (allergies, sinus disease, autoimmune disorders)

Physical Examination

• External eye inspection: Look for redness, crusting, swelling of the puncta, eyelid malposition.
• Fluorescein dye test: Detects corneal abrasions that may irritate the eye.
• Lacrimal drainage assessment:
  • Fluorescein dye disappearance test (FDDT): A drop of fluorescein is placed in the conjunctival sac; normal drainage clears the dye within 5 minutes.
  • Silicone tubing (Jones test): A fine tube is passed through the canaliculi to the nasolacrimal sac; patency is confirmed by saline flow.
  • Nasolacrimal duct probing: Gentle probing assesses for blockage, especially in children.
• Anterior segment photography or slit‑lamp biomicroscopy: Documents eyelid margin disease, punctal stenosis, or foreign bodies.

Imaging (when indicated)

• Dacryocystography: Contrast X‑ray of the lacrimal system; useful for locating the level of obstruction.
• CT or MRI of the orbit and sinuses: Evaluates tumors, sinus disease, or bony abnormalities.
• Ultrasound biomicroscopy: Provides high‑resolution images of the puncta and canaliculi.

Laboratory Tests

Generally not required unless an infectious or systemic inflammatory cause is suspected. In such cases, a complete blood count, allergy testing, or autoimmune panels (ANA, SSA/SSB) may be ordered.

Treatment Options

Treatment is tailored to the underlying mechanism—whether it is excess tear production or a drainage problem. Below is a step‑by‑step approach.

Non‑Pharmacologic & Lifestyle Measures

• Identify and avoid known irritants (smoke, windy environments, harsh cosmetics).
• Use protective eyewear (wrap‑around sunglasses) in windy or dusty conditions.
• Apply warm compresses (5–10 minutes, 2–3 times daily) for blepharitis or meibomian gland dysfunction to improve tear quality.
• Maintain eyelid hygiene with diluted baby shampoo or commercial lid scrubs.
• Limit contact‑lens wear time; consider switching to daily disposables.

Medications

• Antihistamine or mast‑cell stabilizer eye drops (e.g., ketotifen, olopatadine) for allergic conjunctivitis.
• Artificial tears (preservative‑free) to address dry‑eye‑related reflex tearing.
• Topical antibiotics or corticosteroids for infectious or severe inflammatory conjunctivitis (short‑term use only).
• Lacrimal gland suppressants (rarely used; e.g., topical cyclosporine A) when reflex tearing is dominant.

Surgical & Procedural Interventions

1. Punctal plugs (silicone or collagen) – Inserted into the puncta to reduce drainage in cases where tear production is excessive (commonly used for dry‑eye‑related epiphora).
2. Dacryocystorhinostomy (DCR) – Creation of a new drainage pathway between the lacrimal sac and the nasal cavity; performed endoscopically or via external incision. Success rates >90 % for chronic NLDO.
3. Canalicular intubation – Placement of silicone tubes through the canaliculi to maintain patency during healing after probing.
4. Nasolacrimal duct probing & irrigation – First‑line for congenital obstruction; success in infants is >80 % when performed before 12 months of age.
5. Botox (onabotulinumtoxinA) injection into the lacrimal gland – Reduces tear production; useful for refractory reflex tearing.

Adjunctive Therapies

• **Oral antihistamines** for systemic allergic disease (e.g., cetirizine, fexofenadine).
• **Systemic antibiotics** for chronic bacterial blepharitis resistant to topical therapy.
• **Allergy immunotherapy** for patients with confirmed seasonal or perennial allergen sensitivity.

Living with Watery Eyes (Epiphora)

Even after treatment, many people experience intermittent tearing. The following practical tips can improve daily comfort and confidence.

• Carry soft tissues or a reusable microfiber cloth to gently dab excess tears—avoid wiping harshly, which can irritate the skin.
• Apply a thin layer of water‑proof mascara or eyelash glue to keep lashes in place and reduce tear pooling on the lids.
• Use anti‑glare glasses** or a screen filter when working on computers—reduces eye strain that can trigger reflex tearing.
• Maintain a **humidifier** in dry indoor environments (especially in winter) to stabilize the tear film.
• Schedule regular eye‑exam follow‑ups (usually every 6–12 months) to monitor for recurrence or new ocular conditions.
• For children, teach gentle hand‑washing and discourage rubbing the eyes, which can exacerbate irritation.

Prevention

While some causes (aging, congenital blockage) cannot be avoided, many risk factors are modifiable.

• **Allergy control:** Use air purifiers, keep windows closed during high pollen seasons, and follow an allergist’s management plan.
• **Proper eyelid hygiene:** Clean lids daily, especially for contact‑lens wearers and individuals with blepharitis.
• **Protect eyes from irritants:** Wear goggles when gardening, using chemicals, or participating in sports.
• **Limit screen time** or apply the 20‑20‑20 rule (every 20 minutes, look at something 20 feet away for 20 seconds) to reduce ocular surface dryness.
• **Regular dental and sinus health checks:** Chronic sinus infections can precipitate nasolacrimal obstruction.
• **Prompt treatment of eye infections** to avoid scarring of the puncta or canaliculi.

Complications

If left untreated, chronic epiphora can lead to several secondary problems:

• Dermatitis around the eyes from constant moisture (“rheumatic facial dermatitis”).
• Secondary bacterial infection of the conjunctiva or skin (impetigo).
• Blepharitis worsening due to stagnant tears that trap debris.
• Vision disturbances from persistent tear film instability, especially in low‑light conditions.
• Psychosocial impact – embarrassment, reduced quality of life, and avoidance of social situations.
• Rarely, nasolacrimal duct mucocele or **dacryocystitis** (infection of the lacrimal sac) can develop if the blockage is complete and bacteria colonize the stagnant fluid.

When to Seek Emergency Care

Immediate medical attention is required if you experience any of the following:

• Sudden onset of severe eye pain with vision loss.
• Marked swelling of the eyelid or face accompanied by fever (possible dacryocystitis or cellulitis).
• Eye trauma that results in profuse tearing and bruising.
• Discharge that is thick, purulent, or foul‑smelling.
• Blurred vision that does not improve after wiping away tears.

If any of these signs appear, go to the nearest emergency department or call emergency services (e.g., 911 in the United States).
