What causes blocked tear ducts in children?

It is normal for children to have blocked tear ducts because their organs are not yet fully developed. Their tear glands and eyes are generally very small, but their metabolism is very active, so there are a lot of secretions. Parents should not be too anxious or upset when this happens. Be sure to go to the hospital for cleaning in time, and also pay attention to your personal hygiene to avoid infecting your child with some bacteria.

Because long-term tear duct obstruction and inflammatory stimulation can cause serious complications to children: 1. The child's bony tear duct is malformed; 2. Repeated inflammatory stimulation can cause inflammation and adhesion of the lacrimal canaliculus, lacrimal puncta, and nasolacrimal duct; 3. Repeated inflammation can cause fibrosis of the child's tear duct system; 4. The child's tear duct is malformed; 5. Recurrent inflammatory stimulation can cause acute dacryocystitis, chronic conjunctivitis, keratitis, eyelid skin eczema, and even orbital cellulitis in children, and even form severe lacrimal sac fistula; 6. Repeated inflammatory stimulation and repeated tear duct probing will cause the next tear duct intubation operation to fail; 7. Long-term dacryocystitis causes the child's lacrimal sac to dilate. Even if the child grows up and undergoes nasolacrimal sac anastomosis surgery, the lacrimal sac will lose its elasticity and the siphon effect of the tear duct will disappear. Even after my operation, the child will still have symptoms of tearing. I hope you can go to the hospital as soon as possible. Get treatment.

If a child is diagnosed with neonatal dacryocystitis, parents should not be too anxious, because the tear ducts of babies within 6 months are still in the stage of continuous development, and conservative treatment can be adopted first. Generally, antibiotic eye drops are used locally, combined with massage of the skin at the greater corner of the eye (tear sac) to promote the flow of tears toward the nasolacrimal duct. This is done 2 to 3 times a day. For more severe cases, the number can be increased to 4 to 6 times, each time for 1 minute. After a period of treatment, the membrane will rupture on its own and the tear duct will be unobstructed. If the symptoms do not improve after a period of time, you can go to the hospital for pressurized flushing of the tear duct to break the membrane. If the above two methods are ineffective, the tear duct probing can be used to puncture the membrane with a probe to make the tear duct unobstructed. However, if the tear duct is blocked due to bony stenosis or nasal deformity, surgery or other methods should be considered to clear the tear duct.

Therefore, in order to avoid complications, parents still need to pay attention and go to the hospital for cleaning in time. They must also ensure their personal hygiene and not touch their children's eyes with their hands to avoid further infection. They must also avoid their children touching their eyes with their hands, as there are a lot of bacteria on the hands. Therefore, they must pay attention to their usual eating habits and avoid eating spicy foods.
