What is a nasolacrimal pipe?

Nasolacrimal pipe is a channel that allows tears to drain from eyes to the back of the nose. The close examination of the eye reveals two small holes in the corner near the nose. These holes are connected to the nasolacrimal channel that travels on the nasal channel to the rear of the nose. People who wondered why the colds had nose when they cry, no longer be surprised: their rhinitis noses are actually caused by tears flooding the back of the nose.

Under normal conditions, the eye is constantly bathing in tears that are swept through the nasolacrimal channel. Eye drainage ensures that it does not flow, which may look unsightly, and also reduces the risk of eye infection. When people cry, they usually overload the ability to drain the pipe, which causes tears to spill out and from the back of the nose. This is common in people with chronic allergies, which explains why people suffering from hay fever and environmental allergies often have rice owhose. If blocking persists, the eyes may also develop a strong discharge of similar pus. Deleting blocking can be achieved by removing allergen or using drugs to reduce inflammation.

In some cases, it may be necessary to perform dakryocystoplasty in which blocking is surgically removed. Infants who were born with congenital blockages of their nasal canals may require surgery. This is classically done by inserting a small inflatable balloon into the pipeline to open and open it so that the patient's eyes are released correctly. Congenital blockades are sometimes cleaned in themselves, often with the help of fine miles and eye.

There is another fact about the nasolacrimal channel that people can find interesting: because it releases it on the back of the nose and neck, all pathogens inserted into the eyes eventually find the way into the body. That's why people should avoid touching their eyes andThey should always wash their hands first if they need to manipulate their eyes or lids, because they can accidentally spread the infection into their body.
