Question
How to treat children’s lacrimal duct blockage and excessive tearing? Two months ago, the lacrimal duct was cleaned once, and eye drops were applied multiple times a day, but the recovery is not very good. What kind of assistance is needed?
Answer
Children’s lacrimal duct blockage is usually caused by an unbroken membrane at the lower end of the nasal lacrimal duct due to congenital reasons, or by epithelial debris blocking the duct (especially near the lower part of the nasal cavity). In rare cases, it may be due to narrow nasal bones or nasal deformities. The blocked duct’s mucosal lining may lead to bacterial infection, causing dacryocystitis. Since most infants’ lacrimal ducts are still in the developmental stage within the first 6 months after birth, conservative treatment is usually recommended initially.
