Dacryoscintigraph (Tear duct/lacrimal)
Dacryoscintigraphy is widely known to be an effective modality in diagnosing abnormalities of the lacrimal system that cause epiphora (abnormal overflow of tears).
Nuclear imaging can provide a dynamic picture demonstrating the exact point of obstructed flow.
The test is very easily performed with eye drops. We are then able to track the path and progress of the eye drops through the tear ducts (also known as the lacrimal system).
