Lacrimal gland dryness - Causes, Treatment & When to See a Doctor

What is Lacrimal Gland Dryness?

The lacrimal gland is a small, almond‑shaped structure located in the upper outer corner of each eye. Its primary job is to produce the watery component of tears, which lubricates the ocular surface, provides nutrients, washes away debris, and contains antimicrobial proteins that protect against infection. Lacrimal gland dryness (also called lacrimal hypofunction or aqueous‑deficient dry eye) occurs when the gland cannot produce enough fluid to keep the eye adequately moist.

When tear production falls short, the eye’s surface becomes exposed, leading to irritation, visual disturbances, and an increased risk of corneal damage. This condition is a common subtype of dry eye disease (DED) and can affect one or both eyes.

Common Causes

Dryness of the lacrimal gland can be triggered by a variety of systemic, ocular, and environmental factors. Below are the most frequently encountered causes:

• Age‑related changes – Tear production naturally declines after age 40.
• Autoimmune diseases – Sjögren’s syndrome, rheumatoid arthritis, and systemic lupus erythematosus attack the gland’s secretory cells.
• Medication side effects – Antihistamines, antidepressants, beta‑blockers, and isotretinoin reduce tear output.
• Environmental exposure – Low humidity, wind, air‑conditioned or heated rooms accelerate tear evaporation and can suppress gland function.
• Laser eye surgery – LASIK or PRK may temporarily damage corneal nerves that stimulate lacrimal secretion.
• Radiation therapy – Head‑and‑neck radiation can injure the lacrimal gland.
• Infectious or inflammatory conditions – Viral conjunctivitis, chronic blepharitis, or meibomian gland dysfunction can interfere with gland output.
• Neurological disorders – Parkinson’s disease or facial nerve palsy may diminish lacrimal nerve signaling.
• Hormonal changes – Menopause, thyroid disorders, and pregnancy affect tear film quality.
• Systemic dehydration – Inadequate fluid intake or excessive sweating reduces overall body and ocular fluid balance.

Associated Symptoms

Patients with lacrimal gland dryness often notice a cluster of signs that affect comfort and vision:

• Persistent gritty or sand‑like sensation
• Burning, stinging, or itching
• Redness (hyperemia) of the conjunctiva
• Excessive tearing (reflex tearing) that paradoxically follows dryness
• Blurred vision that improves after blinking
• Sensitivity to light (photophobia)
• Feeling of “something in the eye” that does not resolve
• Sticky crusts or discharge upon waking
• Fatigue or difficulty wearing contact lenses

When to See a Doctor

Because untreated lacrimal gland dryness can lead to corneal ulceration, infection, or permanent vision loss, it’s important to seek professional care when any of the following occur:

• Symptoms persist for more than 2–3 weeks despite over‑the‑counter lubricants.
• Recurring episodes of eye redness, pain, or discharge.
• Blurred vision that does not clear after blinking.
• Difficulty wearing contact lenses or need to remove them frequently.
• History of autoimmune disease, recent radiation, or eye surgery.
• Any sudden change in vision, eye pain, or the sensation of a foreign body that does not improve.

Diagnosis

Evaluation typically involves a combination of patient history, physical examination, and specialized tests.

Clinical History

The clinician will ask about:

• Duration and pattern of symptoms
• Medication list, including over‑the‑counter drugs
• Systemic illnesses (e.g., Sjögren’s, rheumatoid arthritis)
• Environmental exposures (smoke, air‑conditioning)
• Previous eye surgeries or trauma

Ophthalmic Examination

• Slit‑lamp biomicroscopy – visualizes the tear meniscus, cornea, and conjunctiva.
• Fluorescein staining – highlights areas of corneal epithelial damage.
• Lissamine green or rose bengal staining – assesses ocular surface cell loss.

Objective Tests for Lacrimal Function

• Schirmer I test – a filter paper strip placed under the lower eyelid measures basal tear production (≤5 mm in 5 minutes suggests aqueous deficiency).
• Tear break‑up time (TBUT) – evaluates tear film stability; a TBUT <10 seconds is abnormal.
• Ocular surface disease index (OSDI) questionnaire – quantifies symptom severity.
• Imaging – Ultrasound or MRI can be used when a mass or structural abnormality of the lacrimal gland is suspected.

Laboratory Work‑up (when systemic disease is suspected)

• Anti‑SSA/Ro and anti‑SSB/La antibodies (Sjögren’s)
• Rheumatoid factor and anti‑CCP antibodies
• Thyroid function tests

Treatment Options

Therapy is individualized according to severity, underlying cause, and patient preference. A step‑wise approach is recommended by the TFOS DEWS II (Tear Film & Ocular Surface Society) guidelines.

1. Lifestyle & Environmental Modifications

• Use a humidifier (30–40% relative humidity) at home or work.
• Take regular breaks during screen use (20‑20‑20 rule).
• Avoid direct airflow from fans, air‑conditioners, or heaters.
• Stay hydrated – aim for at least 8 glasses of water daily.

2. Over‑the‑Counter (OTC) Lubricants

• Artificial tears – preservative‑free drops for frequent use; gel or ointment formulations for nighttime.
• Lubricating eye masks – warm compresses can improve meibomian gland function, indirectly supporting tear stability.

3. Prescription Medications

• Ciclosporin A 0.05% ophthalmic emulsion (Restasis) – reduces ocular surface inflammation and boosts natural tear production.
• Lifitegrast 5% ophthalmic solution (Xiidra) – inhibits T‑cell mediated inflammation.
• Topical steroids (short courses) for acute inflammation under close supervision.
• Autologous serum eye drops – for severe cases; contain growth factors that promote epithelial healing.

4. Punctal Occlusion

Small silicone plugs are inserted into the puncta (tear drainage openings) to retain tears on the ocular surface. This is especially useful when tear production is mildly reduced.

5. Systemic Therapies (when an autoimmune cause is identified)

• Hydroxychloroquine for Sjögren’s syndrome.
• Low‑dose oral corticosteroids or immunomodulators (e.g., methotrexate) for severe inflammatory disease.

6. Advanced and Emerging Treatments

• Thermal pulsation (LipiFlow) – improves meibomian gland function, indirectly aiding aqueous tear stability.
• Intensity‑controlled radio‑frequency (iRF) devices – stimulate lacrimal gland tissue to increase secretion (under investigational study).
• Regenerative approaches – stem‑cell or platelet‑rich plasma eye drops are being evaluated in clinical trials.

Prevention Tips

While some risk factors (age, genetics) are unavoidable, many steps can reduce the likelihood of developing lacrimal gland dryness or lessen its impact:

• Maintain adequate systemic hydration.
• Limit exposure to smoke, pollutants, and windy environments.
• Use protective eyewear (wrap‑around sunglasses) in dusty or windy conditions.
• Schedule regular eye exams, especially if you have an autoimmune condition or take drying medications.
• Adopt the 20‑20‑20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds.
• Consider omega‑3 fatty acid supplementation (e.g., fish oil) which may improve meibomian gland quality; discuss dosage with your physician.
• Keep a balanced diet rich in vitamin A, C, and E – essential for mucin and lipid production on the ocular surface.
