[Radionuclide dacryography in clinical practice and research (author's transl)].
Radionuclide dacryography (RND) has the following indications: 1. Localisation of obstructions in the lacrimal drainage system. 2. Judgement of relative tear obstruction. 3. Pre- and post-operative control of the function of lacrimal drainage in surgical and radiotherapy of the inner canthus region. 4. Investigations of tear secretion are described and own preliminary results are discussed. 5. Resorption of suitable marker substances clinically. First results of conjunctival resorption of pertechnetate are reported. 6. The possibility of testing in vivo radioactive drug delivery systems is shown by means of own investigations. 7. The absorbed radiation dose using RND is very low as compared to radiological methods, thus justifying repeated controls and investigations even in children.
