Treatment of Persistent Chronic Eye Watering Without Itchiness
For persistent chronic eye watering (epiphora) without itchiness, first determine whether the cause is reflex tearing from ocular surface irritation or anatomical obstruction of tear drainage, then treat the underlying cause—most commonly dry eye syndrome with artificial tears and anti-inflammatory agents, or nasolacrimal duct obstruction requiring surgical dacryocystorhinostomy. 1, 2
Initial Diagnostic Approach
The absence of itching effectively rules out allergic conjunctivitis, narrowing your differential significantly. 1 You must distinguish between two primary mechanisms:
- Reflex tearing from ocular surface irritation (paradoxically often due to dry eye syndrome, conjunctival chalasis, or eyelid malposition) 1, 3
- Obstructive epiphora from nasolacrimal duct obstruction or punctal stenosis 4, 2
Key clinical features to identify:
- Tear meniscus height and break-up time to assess tear film stability 1
- Punctate epithelial keratopathy with fluorescein or lissamine green staining indicating dry eye 1
- Redundant conjunctiva at the inferior fornix suggesting conjunctival chalasis 1
- Eyelid laxity or malposition (ectropion, entropion) causing drainage dysfunction 1
- Dye disappearance test to assess lacrimal drainage patency 2
Treatment Algorithm by Etiology
For Dry Eye-Related Reflex Tearing
Start with preservative-free artificial tears used frequently (4-6 times daily initially), as this addresses the most common cause of non-itchy watering. 1, 5
- Lipid-based artificial tears are preferred if meibomian gland dysfunction is present 1
- Refrigerated artificial tears provide additional symptomatic relief through cooling 1
If inadequate response after 2-4 weeks:
- Add topical cyclosporine 0.05% twice daily for anti-inflammatory effect, which requires 6-12 weeks for full benefit 1, 5
- Consider punctal occlusion (temporary collagen plugs first, then permanent silicone plugs) to retain existing tears 1, 5
- Prescribe omega-3 fatty acid supplements systemically for meibomian gland dysfunction 1
For Conjunctival Chalasis
This redundant conjunctiva can obstruct tear drainage and cause chronic irritation. 1
- Mild cases: Treat with lubricants and mast-cell stabilizers 1
- Persistent symptoms: Surgical intervention with thermal or chemical cautery to tighten redundant conjunctiva, or conjunctival resection 1
For Nasolacrimal Duct Obstruction
The traditional surgical approach remains most effective. 4, 2
- External dacryocystorhinostomy (DCR) has 85-95% success rate and is the gold standard 4, 2
- Powered endoscopic DCR has comparable outcomes to external DCR with no facial scarring 2
- Nasolacrimal stent implantation has lower long-term success rates and is not recommended as primary treatment 4
Medical management with nasal steroid spray may be attempted first in partial obstructions, but most cases require surgical intervention. 2
For Eyelid Malposition-Related Epiphora
- Eyelid laxity with nocturnal ectropion (floppy eyelid syndrome) requires eyelid tightening procedures 1
- Associated conditions include obesity, sleep apnea, and thyroid disease—address these systemically 1
Common Pitfalls to Avoid
Do not assume watering eyes mean excess tear production—paradoxically, dry eye syndrome is a leading cause of reflex tearing. 1, 3 The ocular surface irritation from tear film instability triggers compensatory hypersecretion.
Avoid topical vasoconstrictors for chronic use, as prolonged use causes rebound hyperemia and conjunctivitis medicamentosa. 1
Do not use preserved artificial tears more than 4 times daily, as preservatives cause ocular surface toxicity. 1 Switch to preservative-free formulations for frequent use.
Screen for medication-induced causes: topical glaucoma medications, NSAIDs, and antivirals commonly cause chronic irritation and reflex tearing. 1 Consider preservative-free alternatives or medication adjustment.
When to Refer to Ophthalmology
Immediate referral is warranted for: 1, 6
- Visual loss or significant vision impairment
- Moderate to severe pain suggesting corneal involvement
- Corneal scarring, neovascularization, or ulceration 1
- Lack of response to initial conservative therapy after 4-6 weeks 6, 7
- Suspected nasolacrimal duct obstruction requiring surgical evaluation 2
Follow-Up Strategy
Re-evaluate at 3-4 weeks after initiating treatment to assess response. 1, 7 For dry eye management, full therapeutic effect of anti-inflammatory agents takes 6-12 weeks. 1, 5
If using topical corticosteroids (rarely needed for non-allergic watering), monitor intraocular pressure and evaluate for cataract formation with periodic examinations. 1
