H04.572

Clinical Causes: Chronic inflammation or infection of the lacrimal sac, such as dacryocystitis Previous trauma or injury to the area around the eye or tear drainage system Congenital abnormalities present at birth that cause narrowing Scarring from injuries or surgeries affecting the tear drainage pathways Tumors or growths that obstruct the lacrimal sac or its ducts Degenerative changes related to aging can also lead to narrowing Systemic inflammatory conditions, such as sarcoidosis or Wegener's granulomatosis

Key Symptoms: Persistent tearing (epiphora) from the affected eye, especially when emotional or in windy conditions Recurrent or chronic infections around the eye or tear sac area Discomfort or a sensation of fullness near the inner corner of the eye Redness and swelling of the eyelid or surrounding tissues Mucous or purulent discharge from the eye Possible blurred vision due to tear over-accumulation Discoloration or darkening around the inner eye in some cases

Diagnosis Path: Dye disappearance test to observe tear flow Jones dye test to assess tear drainage efficiency Slit-lamp examination to inspect the tear sac and surrounding areas Imaging studies such as dacryocystography or dacryoscintigraphy to visualize the tear drainage pathways Palpation of the lacrimal sac area to identify tenderness or swelling Culture or biopsy if infection or tumors are suspected

Treatment Protocols: Conservative management with warm compresses and massage to promote drainage Antibiotic or anti-inflammatory medications to treat infections or inflammation Dacryocystorhinostomy (DCR), a surgical procedure to create a new tear drainage pathway bypassing the blockage Endoscopic procedures to remove obstructions or scarring within the tear ducts Monitoring and managing underlying systemic conditions that may contribute to the stenosis Post-operative care with antibiotics and follow-up appointments to ensure proper healing
