Abstract

To evaluate the diagnostic efficacy of dacryoscintigraphy, we examined Hones dye test and dacryoscintigraphy in 24 eyes of 18 patients who were suspected to have junctional block in lacrimal drainage system. Among 18 eyes that were negative to Jones I dye test, 3 showed punctal stenosis and 6 typical pattern of lax lid and 2 partial obsturction of nasolacrimal duct on dacryoscintigraphy. In evaluation of lacrimal drainage system, physiological aspect is as important as anatomical information since lacrimal pumping action of lid and tear flow as well as the patency of lacrimal passage contribute to the lacrimal drainage. Compared to Jones dye test, dacryoscintigraphy is more useful with certain advantages : It gives less discomfort to patients, provides anatomical information and does not depend on examiner`s skills.
