Lacrimal duct blockage in adults can be divided into two parts, one part is the blockage of the lacrimal tubules or the common lacrimal duct and one part is the blockage of the nasolacrimal duct. Surgery, medication, and physical therapy can be used. 1. Surgical treatment: If the lacrimal duct or the common lacrimal duct is blocked, it can be treated by tear duct probing or silicone tube implantation, silicone tube implantation is also applicable to nasolacrimal duct obstruction, and the lacrimal sac nasolacrimal anastomosis surgery is also suitable for nasolacrimal duct obstruction. Nowadays, the best treatment surgery for lacrimal duct obstruction is endoscopic laser exploratory surgery, and if the condition is serious, the patient can also be retained in the lacrimal stent. 2. Medication: For patients with inflammation of lacrimal duct obstruction, aminoglycoside drugs can be used, such as streptomycin and neomycin, which are effective in treating Gram-negative bacteria; or quinolones, such as levofloxacin and ciprofloxacin, which should be used according to the doctor’s instructions, but are prohibited for pregnant women and minors. 3. Physical therapy: hot towels can be used to compress the eyes, which can promote the absorption of inflammation and achieve the effect of adjuvant therapy. If there is a blockage of the tear duct, you should go to the hospital in time, the specific treatment should be carried out under the guidance of the doctor.
