What are the causes of lacrimal irrigation false passage

summary

Some people may cause false passage due to carelessness or other reasons when washing the lacrimal passage, so we need to be very careful. Let's talk about the causes of false passage.

What are the causes of lacrimal irrigation false passage

First: under normal circumstances, lacrimal passage is unobstructed, lacrimal excretion function is normal, lacrimal sac is not easy to be infected by bacteria. When the nasolacrimal duct is narrow or blocked, the lacrimal fluid will stay in the lacrimal sac for a long time, stimulating the lacrimal sac mucosa, making it inflamed and thickened, which is conducive to the growth and reproduction of bacteria entering the lacrimal sac, leading to inflammation and suppuration. In addition, a small number of dacryocystitis is caused by ocular trauma, trachoma, sinusitis, tuberculosis, etc. There are more than ten kinds of bacteria causing infection and suppuration, such as Diplococcus pneumoniae, Staphylococcus, Streptococcus, etc.

Second, it is suggested that eye drops and lacrimal passages be rinsed first. It is recommended that you drop acyclovir eye drops and norfloxacin eye drops alternately, once every 2 hours. The washcloth must be boiled and disinfected 2-3 times a day, and should be used alone to prevent repeated infection. If not, surgical treatment.

Third: the cause of chronic dacryocystitis is obstruction or stenosis of nasolacrimal duct, and the common cause of obstruction or stenosis is inflammation of external eye, such as trachoma, conjunctivitis, blepharitis, lacrimal canaliculitis, etc. In addition, it is also related to the width and length of nasolacrimal duct, deviation of nasal septum, hypertrophy of inferior turbinate and chronic rhinitis.
