Blocked lacrimal ducts can manifest as swelling of the lacrimal gland, which can be secondary to lacrimal gland inflammation and can induce systemic infection in severe cases. If there are no symptoms of infection, the blocked lacrimal cyst can be surgically removed. If there is secondary infection, anti-inflammatory antibiotics should be used adequately before surgical removal. The lacrimal duct consists of four parts: the tear duct, the lacrimal duct, the lacrimal sac, and the nasolacrimal duct. Blockage of the lacrimal duct can cause tear overflow, dacryocystitis and other disorders, increasing discomfort and affecting daily work and life. There are many ways to treat blocked lacrimal ducts, which need to be treated symptomatically according to the disease triggering factors and the location of blockage. I, inflammatory changes 1, massage: if the tear duct structure is inflamed, the blockage may be caused by mucosal swelling, early advice to give regular local massage and compression in the tear sac area to promote the opening of the nasolacrimal duct; 2, tear duct probing: antibiotics can be applied to anti-infection, such as epinephrine to relieve the inflammatory response of the eye structure, etc. If necessary, a probe can be used to expand the tear duct. Second, organic lesions 1, tear ductotomy: If the blockage is caused by organic lesions, scarring has been formed, the tear duct can be cut open to release the blockage; 2, tear duct tear sac end-lateral anastomosis: If the blockage is near the tear sac, the blockage can be removed and the tear sac can be sutured to the remaining tear duct, which can also release the blockage symptoms; 3, tear sac nasal anastomosis: If the combined nasolacrimal duct blockage The tear sac can be directly anastomosed with the nasal cavity, and the plasma secreted by the lacrimal gland can be directly drained into the nasal cavity to relieve the symptoms of blockage; 4.replacement of the lacrimal duct: if the blockage site is long, the complete removal will affect the drainage, and a conjunctival piece should be used to recreate a drainage lacrimal duct. The cure rate of blocked lacrimal ducts is high after systematic treatment. If you suffer from this disease, you should consult a doctor in time, and regular treatment can shorten the course of the disease and speed up the recovery.
