Everyone has it! What are those mysterious “tiny holes” on your eyelids? Few people have ever noticed a small hole on the inside of their eyelid. Do you know what its function is?
Every human being has this mysterious hole, and it is a different size from person to person. It is located about 2 millimeters from the สมัครสมาชิก UFABET วันนี้ รับเครดิตฟรีทุกวัน inner corner of the eye. It is the lacrimal punctum .
Don’t confuse it with the lacrimal gland, because this hole is not used to produce tears. Instead, it has the function of draining tears to help us.
These tear ducts actually exist on both the upper and lower eyelids. They connect and drain tears to the lacrimal sac, which extends down to the front of the nasal passages.
This connection between the tear and nasal passages helps us understand why when we cry, our nose also runs, or why we can secretly taste our tears when we cry.
In some patients with Dry Eye Syndrome, ophthalmologists use a treatment called a plug made of silicone or collagen to reduce tear leakage and keep the eye moist and protected from infection.
But on the other hand, this tear duct can sometimes flow back. The things that flow back can be tears, air, mucus, and blood coming out of the nose.
If there are suspicious symptoms related to the eyes, do not ignore them. You should see a doctor immediately for a detailed diagnosis. If any abnormalities are found, they can be treated quickly. Because the eyes are very delicate, we must be extra careful, whether it is an examination or treatment. It requires the expertise and experience of an ophthalmologist only.
