Abstract:
A new scintigraphic method, the radionuclide dacryography, to evaluate lacrimal drainage and its disorders is described. A drop of 99mTc-pertechnetate is dropped onto the eyes and the transport of the nuclide is registered by a scintillation camera. By this method it is easy to verify, under physiological conditions, suspected obstructions of the lacrimal drainage system and to determine its localization. The absorbed radiation dose using radionuclide dacryography is very low as compared to radiological methods.
