Lacrimal dacryoscintigraphy

Semin Nucl Med. 1984 Jan;14(1):8-15. doi: 10.1016/s0001-2998(84)80050-1.


Lacrimal dacryoscintigraphy facilitates definite diagnosis of obstructions and stenosis of the lacrimal drainage system with little stress to the patient. Together with x-ray dacryocystography it is an important diagnostic tool especially for pre- and postoperative evaluation of the drainage apparatus. Dacryoscintigraphy is the best method for measuring the dynamics of tear drainage especially in the canaliculi. Although it is not a substitute for other methods in general use, it complements them and expands their diagnostic accuracy.
