What Is Lacrimal Scarring?

Lacrimal scarring refers to fibrotic changes in parts of the lacrimal system, including the puncta, canaliculi, lacrimal sac, or surrounding conjunctiva and lids. Scar tissue can narrow or block the tear drainage pathway, leading to chronic tearing and recurrent infections. It often follows trauma, surgery, radiation, or severe inflammation of the ocular surface or adnexa. The degree of scarring ranges from subtle narrowing to complete obliteration of channels. Management focuses on restoring or bypassing normal tear flow.

Causes and Sites of Lacrimal Scarring

Common causes include prior dacryocystitis, canaliculitis, or trauma that heals with fibrosis. Eyelid lacerations near the punctum, tumor excision, and cosmetic procedures can disrupt the drainage anatomy. Cicatrizing conjunctival diseases such as Stevens Johnson syndrome, ocular cicatricial pemphigoid, and trachoma often scar the puncta and canaliculi. Radiation therapy to the orbit or nasal region may also damage lacrimal tissues. The location of scarring determines whether punctal, canalicular, or nasolacrimal segments are most affected.

Clinical Features and Functional Impact

Patients usually complain of chronic epiphora, sometimes accompanied by recurrent redness or discharge from the inner canthus. On examination, the puncta may appear narrowed, closed, or everted away from the tear lake. Probing and irrigation can reveal strictures, complete blockages, or false passages. In severe cicatricial disease, symblepharon, lid margin distortion, and keratinization of the conjunctiva accompany lacrimal changes. Chronic tearing affects comfort, visual clarity, and quality of life.

How Is Lacrimal Scarring Diagnosed?

Diagnosis combines history of prior disease or surgery with detailed examination of the eyelids and lacrimal drainage pathway. The eye doctor inspects punctal shape and position and performs probing and irrigation to map where flow is obstructed. Dacryocystography or dacryoscintigraphy can image the anatomy and function of the lacrimal system when planning surgery. Evaluation for underlying cicatricial disorders may involve conjunctival biopsy and systemic workup. Distinguishing structural scarring from simple functional pump failure guides treatment.

How Is Lacrimal Scarring Managed?

Treatment options range from punctal dilation and stenting to more extensive reconstructive surgery. Mild punctal stenosis may respond to dilation or punctoplasty to enlarge the opening. Canalicular and nasolacrimal duct scarring often require intubation with silicone stents, dacryocystorhinostomy, or conjunctivodacryocystorhinostomy with a bypass tube. Active cicatricial disease is treated with systemic immunosuppression to limit further scarring. Long term follow up monitors tear drainage, ocular surface health, and recurrence of fibrosis.

FAQs About Lacrimal Scarring

Can lacrimal scarring go away on its own?

Established scar tissue does not typically regress, though mild stenosis can soften slightly over time. Most meaningful improvement comes from surgical or procedural intervention.

Why did I still have tearing after infection was treated?

Acute infection may clear, but the healing process can leave behind scarring that continues to block drainage. That is why some patients need procedures even after the infection is gone.

Will surgery for lacrimal scarring cure my tearing permanently?

Many patients get long lasting relief, but outcomes depend on the extent of scarring and underlying disease. Re scarring or partial blockage can occur, especially in ongoing cicatricial conditions.

Can lacrimal scarring harm the eye surface?

Constant overflow tears can irritate the skin and blur vision, while associated cicatricial disease can damage the ocular surface itself. Treating both the scarring and the surface disease protects comfort and sight.
