Tears May Be A Disease!

August 08, 2025

ears are the most effective "remedy" for relieving the mental burden. A joyful cry can relieve the depression and grievances in the heart. However, if the eyes keep running out of tears, you need to pay attention to it. It is very likely that you are suffering from lacrimal disease.

Repeated tears may be caused by blocked tear ducts


Human eyes will constantly produce tears to moisturize the cornea. There is a small finger-sized gland called the lacrimal gland on the outer upper part of the eyeball. Usually the lacrimal glands keep making tears and moisten our eyeballs. At the corner of the eye, there is a small tube leading to the nasal cavity, called the lacrimal duct. Except for some of the usual tears that evaporate, the rest are all entered into the nasal cavity from the nasolacrimal duct, so we can't feel any tears.



However, if the lacrimal duct is narrow or blocked, tears cannot flow into the nasal cavity, throat and other parts along the lacrimal duct, but can only flow out of the body, so the phenomenon of tearing will occur. Many people don't know enough about lacrimal diseases and mistakenly think that "watering tears" is a trivial matter, leading to delays in treatment.


Lacrimal disease is an "invisible killer" that endangers eye health


Lacrimal disease poses a serious threat to the eyes. The tear duct is like the "sewer" of our tears, and the lacrimal sac is the "reservoir" of the sewer. Blocked or inflamed lacrimal ducts will cause the drainage of the "sewer" to slow down or even fail to drain, leading to continuous tearing.



If the "sewer" is blocked for a long time, the tears in the lacrimal sac will not move, and bacteria will easily breed. Over time, infection and inflammation will cause lesions in the lacrimal sac, which will be complicated by chronic inflammation of the lacrimal sac. After the lesions, the corners of the eyes are not only tears, but also purulent secretions.


Lacrimal disease needs timely treatment. Acute attack of chronic dacryocystitis will not only cause obvious redness, swelling, heat and pain in the corners of the eyes, but also the inability to open the eyes and visual disturbance on the affected side, which makes the patient unable to work and rest.
