Introduction
Management of nasolacrimal duct obstruction in children includes massage of the lacrimal sac area, lacrimal irrigation, probing, laser dacryoplasty, and dacryocystoplasty. The appropriate intervention should be selected based on the child's age and severity of obstruction; early treatment can reduce complications. If a child experiences persistent tearing or increased eye discharge, prompt medical evaluation is recommended.

Management options for pediatric nasolacrimal duct obstruction include lacrimal sac massage, lacrimal irrigation, probing, laser-assisted dacryocanalicular surgery, and dacryoplasty. The appropriate intervention should be selected based on the child's age and severity of obstruction. Early treatment can help reduce complications. If a child experiences persistent tearing or increased eye discharge, prompt medical evaluation is recommended.

1. Lacrimal sac massage: Suitable for infants under 6 months old. Parents should wash their hands thoroughly and then use the index finger to apply gentle downward pressure from the lacrimal sac area along the side of the nose. This pressure may help open the membranous blockage in the tear duct. Perform 2–3 times daily for 5–10 minutes each session.

2. Lacrimal irrigation: Involves flushing the tear duct with a specialized solution. This procedure helps identify the site of obstruction and may clear mild adhesions or foreign material. It is suitable for infants who do not respond to massage or those with mild obstruction.

3. Lacrimal probing: A common treatment for pediatric nasolacrimal duct obstruction, this procedure involves gently passing a fine probe through the blocked tear duct to restore patency. It is quick and effective, with most children achieving an open tear duct after a single procedure.

4. Laser-assisted tear duct therapy: Uses the thermal effect of laser energy to open narrowed or obstructed areas of the tear duct. It is minimally invasive with rapid recovery, suitable for children with moderate obstruction or recurrent blockage after probing.

5. Dacryoplasty: Surgical reconstruction of the tear drainage pathway, indicated for severe obstruction or cases complicated by dacryocystitis. This procedure requires general anesthesia and regular postoperative care.

For daily care, maintain good eye hygiene by gently wiping away secretions with sterile cotton swabs. Avoid rubbing the eyes to prevent bacterial infection. Use gentle pressure during massage to avoid damaging eye tissues. Follow medical advice closely to support successful recovery of tear duct function.

Who should not eat mixed-breed chicken
People who should avoid consuming undercooked chicken generally include pregnant women, infants and young children, individuals with weakened immune systems, those with poor digestive function, and people with underlying medical conditions. Undercooked chicken may carry pathogenic microorganisms such as Salmonella and Toxoplasma gondii. These pathogens can easily cross the placenta and affect fetal development, increasing the risk of birth defects, miscarriage, and other complications. They may also cause infections in pregnant women themselves, leading to symptoms such as fever and diarrhea.
