Diagnosis Path: Diagnosis typically involves a thorough eye examination and assessment of tear flow. The healthcare provider may perform specific tests such as: - Syringing and flushing of the tear ducts to check for blockages - Dyes or fluorescein tests to observe tear drainage pathways - Imaging studies like dacryocystography or ultrasound if structural issues are suspected - Evaluation of eyelid function and structure Confirming the diagnosis often involves ruling out other causes of excessive tearing or eye irritation.

Treatment Protocols: Treatment options depend on the severity and underlying cause of the drainage insufficiency. Common approaches include: - Conservative measures such as eye lubrication and hygiene - Medical management with antibiotics if infection is present - Procedures to open or enlarge blocked tear ducts, such as dacryocystorhinostomy (DCR) - Balloon dilation of the tear ducts to restore drainage - Surgical removal of obstructions or growths - In some cases, temporary or permanent tear stents may be placed to maintain drainage pathways Follow-up care is important to monitor the effectiveness of treatments and prevent recurrences.
