Lacrimal duct diseases mainly refer to lacrimal duct obstruction (including upper and lower lacrimal canaliculus obstruction, common lacrimal duct obstruction, nasolacrimal duct obstruction and chronic dacryocystitis). ). Patients with this kind of eye disease often have symptoms such as tears overflow and pus discharge, which brings endless troubles and pains to patients. Lacrimal duct obstruction can occur in any part of the lacrimal duct, mainly in the lacrimal punctum, lacrimal canaliculus, lacrimal sac-nasolacrimal duct junction and the lower mouth of nasolacrimal duct. Patients with lacrimal duct obstruction shed tears for a long time, which not only affects their eyesight, but also hinders their appearance. Patients with chronic dacryocystitis are also accompanied by purulent canthus.
1, acute dacryocystitis, mostly caused by chronic dacryocystitis. The skin in the lacrimal sac area is red, swollen, painful and tender. In severe cases, symptoms such as general malaise and fever may occur. After the abscess matures, it can be punctured by the skin surface to form a fistula. Antibiotics should be used all over the body in acute phase, and after acute inflammation subsides, it should be treated according to the principle of chronic dacryocystitis.
2, chronic dacryocystitis, due to the obstruction of nasolacrimal duct, bacteria and tears accumulate in the blocked lacrimal sac, and often stimulate the mucosa of the lacrimal sac wall, causing chronic inflammation. Tears are prominent symptoms. The treatment method is to squeeze out pus at any time, drop antibiotic eye drops locally, and wash the lacrimal sac with normal saline or antibiotics every day or every other day until the pus disappears, but exploration can be considered, but in most cases surgery is needed.
