Miscellaneous.

Several methods are available to examine the function and morphology of the lacrimal drainage system under physiological conditions. Radionuclide scintigraphy is a sensitive method which is not cumbersome for the patient. Dacryoscintigraphy was first introduced by Rossomondo et al. in 1972. Since then the method has been modified by several groups and its significance supported by numerous studies. Indications of dacryoscintigraphy are obstructive disorders of the lacrimal drainage system. The method is helpful in the diagnosis of tear flow disturbances and in the follow-up for the detection of therapy response (von Denffer et al. 1984; Brockmann et al. 2005). [ABSTRACT FROM AUTHOR]
