Tear Duct Scan

This procedure can also be called Lacrimal duct scanning or Dacryoscintigraphy. The purpose of performing the Lacrimal Scan is that a radioactive tracer, when placed in your eyes (like an eye drop), will follow the path of tears. Pictures will be taken of the tear ducts to make sure there are no blockages.

Test Preparation


Exam Procedure

A radioactive droplet will be dripped into the eyes. You will be placed (in the sitting position) in front of a gamma camera, which will take pictures of the tear ducts. The test will take approximately 30 minutes.
