Patient's question:
What is the best way to deal with congenital nasolacrimal duct obstruction? This child has had this condition for some time, and we are hesitant to give medication. Please provide some advice from a doctor.Doctor's answer:
In fact, there are many reasons why children cry. Except for eye trauma, most are congenital abnormalities, such as nasolacrimal duct dysplasia (including congenital nasolacrimal duct obstruction, abnormal development of lacrimal puncta or lacrimal canals), eyelid dysplasia (including corneal endothelium, entropion and ectropion), and eye diseases (such as glaucoma). The most common cause of nasolacrimal duct obstruction in children is that the end of the nasolacrimal duct is close to the nasal cavity. A thin valve should open at birth. If it doesn't open, it will lead to poor drainage of tears. Clinically, it manifests as constant tearing, continuous tears, and increased secretions. If pressure is placed on the lacrimal sac, sometimes mucus or pus may flow from the tears, often accompanied by conjunctivitis, red eye, and discharge. Severe cases can even lead to lacrimal sac inflammation, bacterial infection, and acute dacryocystitis.
