kyynelpussi

Kyynelpussi is a Finnish term that translates to "tear sac" or "lacrimal sac". It refers to the anatomical structure that collects tears from the eye and drains them into the nasal cavity. This sac is part of the lacrimal apparatus, which is responsible for tear production and drainage.

The lacrimal sac is a small, thin-walled pouch located in a groove on the medial side of the orbit, near the nose. It receives tear fluid from the canaliculi, which are small ducts that drain tears from the inner corner of the eye. From the lacrimal sac, tears flow down into the nasolacrimal duct, a tube that empties into the nasal cavity. This drainage system helps to keep the surface of the eye moist and clean.

When this system is blocked or inflamed, it can lead to various medical conditions. A common issue is dacryocystitis, an infection of the lacrimal sac, which can cause pain, swelling, and redness around the inner corner of the eye, as well as a discharge. Blockages in the nasolacrimal duct can also cause excessive tearing, known as epiphora. Medical professionals may use procedures to diagnose and treat these conditions, such as probing the duct or surgical intervention in persistent cases.
