A good number of babies are born a few weeks or so after birth, careful parents find that one or both eyes of their children give the impression of tears all day long, and some children have a constant discharge, but otherwise, the child has almost no other signs of eye discomfort, what is going on? An ophthalmologist will tell you: your child may have a congenital tear duct obstruction. In a few children, there is a membrane at the lower end of the nasolacrimal duct that does not open, so the tears gather in the tear sac and do not flow down properly, so they spill out of the eye without a normal channel. In some babies, the tears in the tear sac bacterial multiplication, light pressure on the tear sac can be seen pus-like discharge overflow, this is congenital dacryocystitis. After the baby has this condition, young parents are worried all day long and the grandparents of the child seem to have a snack. In fact, the prognosis for the majority of children with this condition is very good as long as they are treated promptly! When a child has overflowing tears, he or she should be promptly examined at the hospital. After excluding other eye diseases (such as conjunctivitis, glaucoma and astigmatism) and confirming the diagnosis of congenital lacrimal duct obstruction, the following treatment can be carried out: In the early stage (before the child is 2 months old, or just come to the clinic), you can choose appropriate antimicrobial eye drops according to the bacterial culture report of the secretion, and do local massage in the tear sac area. The purpose of massage is to squeeze out the secretion, so that eye medicine can enter the tear sac more easily, which is conducive to the control of inflammation, and the second is that some children can open the nasolacrimal duct through massage to achieve the purpose of radical treatment. Massage should be completed under the guidance of a specialist, pay attention not to hurt the baby’s delicate eyeballs. If the baby is not effective after massage and eye medication, or if there is no purulent discharge but there is still tearing, tear duct flushing and exploratory treatment should be carried out promptly. After observation and comparison in major hospitals, it is now believed that the best results of flushing and probing are achieved if the child does not have acute inflammation before the size of 6 months, especially the highest success rate of one-time probing around the size of 4 months. A few children who still have purulent discharge after active massage and eye medication do not have to wait passively, but should have their tear ducts flushed with an appropriate antimicrobial solution, and then be promptly probed, with systemic antibiotics applied according to the situation after probed. Otherwise, the result of long-term waiting is the mechanization of the lacrimal mucosa and the membrane at the lower end of the nasolacrimal duct, resulting in treatment failure and later only surgery or laser treatment. The clinic often encounters children who are first seen after the age of one year, so the results of such treatment are of course poorer, which is indeed a pity.
