H04.543

Clinical Causes: Chronic inflammation or infections affecting the tear drainage system Previous eyelid or eye surgeries that may cause scarring and narrowing Trauma or injury to the eye or eyelids leading to structural damage Congenital anomalies present at birth affecting the tear drainage pathways Scar formation from conditions like chronic conjunctivitis or dacryocystitis Age-related changes causing weakening or narrowing of the tear ducts Foreign bodies or debris causing persistent irritation and inflammation

Key Symptoms: Excessive tearing (epiphora), especially during activities or in bright light Recurrent eye infections or conjunctivitis due to poor tear drainage Discharge from the eyes which may be clear or pus-like Swelling or tenderness around the inner corner of the eyelids Blurred vision caused by excessive tearing or irritation Crusty buildup on eyelids or lashes, especially in the morning Discomfort or a feeling of obstruction in the tear ducts

Diagnosis Path: Dye disappearance test to evaluate tear drainage efficiency Jones' testing, involving dye instillation and checking for its passage through the tear ducts Lacrimal irrigation or probing procedures to observe the flow of fluid and detect blockages Imaging techniques like dacryocystography or dacryoscintigraphy to visualize the anatomy of the tear ducts Slit-lamp examination to look for signs of inflammation, infection, or scarring

Treatment Protocols: Conservative approaches such as warm compresses and topical antibiotics for associated infections Dilation or probing of the tear ducts to open narrowed passages Surgical procedures like dacryocystorhinostomy (DCR) to create a new tear drainage pathway Lacrimal stenting or intubation to keep the canaliculi open during healing Treatment of any underlying inflammation or infections to prevent recurrence In severe cases, tear duct reconstruction or bypass procedures may be considered
