H04.412

Clinical Causes: Blockage in the tear drainage system, often due to swelling or scarring of the lacrimal sac or duct. Chronic infection caused by bacteria, fungi, or other pathogens that persist within the lacrimal sac. Previous eye infections or trauma that lead to structural changes obstructing tear flow. Anatomical abnormalities, such as narrowing (stenosis) of the tear ducts, present from birth or acquired over time. Inflammatory conditions, such as dacryocystitis, which can progress to become chronic if not properly managed.

Key Symptoms: Persistent tearing or watery eyes, especially on the affected (left) side. Repeated or ongoing infection signs, including redness and swelling in the inner corner of the eye. Tenderness or discomfort around the tear sac, often worsening with pressure. Discharge from the eye, which may be thick, mucous-like, or pus-filled. Blurred vision or a sensation of pressure in the affected area. Crusting around the eyelid or tear duct opening, especially upon waking. Occasional episodes of acute infection with sudden pain, redness, and swelling.

Diagnosis Path: To diagnose chronic dacryocystitis of the left lacrimal passage, healthcare providers typically perform a combination of clinical assessments and diagnostic procedures. These may include: - Physical examination, focusing on the eye, eyelids, and tear sac area. - Syringing or probing of the tear ducts to evaluate blockage. - Dacryocystography (imaging technique using contrast dye) to visualize the tear drainage system. - Craniofacial imaging studies, such as CT scans, in complex cases. - Swab or fluid analysis for identifying infectious agents if discharge is present.

Treatment Protocols: Treatment options vary based on severity and cause, but generally include: - **Conservative approaches**: - Warm compresses applied to the affected area to reduce swelling. - Massage techniques to promote tear drainage. - Antibiotic or anti-inflammatory eye drops or ointments to control infection and inflammation. - **Surgical interventions**: - Dacryocystorhinostomy (DCR): a common procedure creating a new passage for tear drainage when the original duct is blocked. - Balloon dacryoplasty: minimally invasive method to open narrowed tear ducts. - Dilation of the tear duct or removal of obstructions. Consultation with an ophthalmologist experienced in tear duct disorders is essential for personalized management and treatment planning.
