Dacroscintigram (tear duct)
This is a test to look at the drainage of the tear ducts. It does not involve an injection; instead a small amount of a radioactive tracer will be dripped into the corner of each eye. While you sit in front of a gamma camera, a series of images will be taken as these drops drain from the eye. The imaging may take from 20 minutes up to an hour.
After all the images are completed, the technologist will check them before you go home. We will not be able to give out the result of the study immediately but a written report will be sent to the referring doctor. There are no side effects from the test.
