H04.5: Stenosis and insufficiency of lacrimal passages

Tear fluid flows out of the eye via the tear ducts. The tear ducts begin in the inner edge of the upper and lower eyelids. In both places there is a small opening that opens into a narrow channel. The channels join and carry the tear fluid to the inside of the nose.

There are different reasons why the tear fluid is unable to flow away properly. For example, the tear ducts may be constricted or blocked, for example. It is possible, too, that the opening for the tear ducts in the inner edge of your eyelid is not in its proper position in the eye. The tear fluid may then not flow in. If the tear fluid does not drain properly it can make the eye water constantly.
