What are the tears?

also, also known as tears, are small anatomical structures that are part of a system that are part of a system that cleans tears from the eyes. These small channels connect two holes in the inner corners of the eyes with the nasolacrimal channels that emptied into the nose. These small pipes may have a number of problems, including narrowing, blocking and infection.

To understand the role of tear channels, it helps to understand how tears are usually made and removed from the eyes. Tears production takes place in tear glands, which are located above the eyes. They eliminate tears into the upper outer corners of the eyes and flashing the lids allows the tears to spread evenly over the eye surfaces. The excess fluid is collected in the inner corner of the eye and eventually enters two small holes called the Puncta Lacrimalia. The tear channels connect these two punch to the hell, which is emptying the channel, which carries tears on the opening inside the nose.

Lacrimal Canaliculi therefore serves as an important part of the tract that can leave the tears. Each eye is exhausted by two channels, although these channels sometimes converge into one tube before emptying into the hell. Canaliculi is surrounded by elastic tissue and can be expanded to twice or three times their normal size when tears are increased. The reflux of the liquid back into the eyes is usually prevented by the Rosenmüller valves.

There may be a number of problems with lactrimal channels. Closing or narrowing of these channels may result in a number of conditions. Some children are born without their channels to open up fully, which is known as the congenital agenesis of the canalicular system. They often suffer from excessiveness and redness of the eyes. Adults may also have blocked or tapered channels, but this is usually obtained as a complication of viral infection.

Some pathogenic agents can selectively infect tear channels, resulting in a condition called CanaLicultis. Disabled patients experience itching, redness of the eye and discharge from the inner corner of the eye. This may be due to the Candida albicans , Actinomyces Israels or http://www.wisegeek.com/preview.htm?id=188364. Without proper treatment, this infection can cause blocking these channels.

Another problem that people with their hell may have is the poorly functioning Rosenmüller valves. These patients may have a back flow of nasal secretion into the eye. When they blow their noses, they could notice bubbles or watery outflows. Although it may concern patients, it is usually a benign order.
