Blocked Tear Ducts: Dye Disappearance Test
A fluorescein dye disappearance test is used in children and adults to find out whether tears are draining normally from the eyes into the nose.
Normally, tears sweep the dye out of the eye and into the tear ducts. If dye stays in the eye, the tear duct may be blocked.
Both eyes are usually tested and compared during this test, which is done after other exams have not clearly shown that the duct is blocked.
A baby may fuss and cry during this test. Parents are often asked to hold and soothe their child while he or she is being tested.
