J.1; KENNEDY, N.2 Author Information Departments of 1Ophthalmology and 2Medical Physics, Ninewells Hospital and Medical School, Dundee DD1 9SY, UK Nuclear Medicine Communications: June 1992 - Volume 13 - Issue 6 - p 416-420 Buy Abstract The value of lacrimal scintigraphy in the assessment of nasolacrimal duct obstruction was determined by comparing the results with syringing in 67 patients (83 eyes). As expected, of 28 lacrimal drainage systems which were obstructed on syringing, 23 (82%) had abnormalities of tear drainage on scintigraphy. However, in 55 lacrimal drainage systems that were patent on syringing, 19 (35%) were normal, but in 36 (65%) abnormalities not apparent on syringing were detected on scintigraphy. Thus scintigraphy is a very useful technique in the assessment of nasolacrimal duct obstruction particularly in systems patent on syringing. Since the site of obstruction can be determined, lacrimal scintigraphy can facilitate the planning of the appropriate surgery. © Lippincott-Raven Publishers.
