title: [Dacryocystography in digital subtraction technique].
abstract: The authors emphasize the usefulness of dacryography to approach patients affected by epiphora. Digital dacryocystography had improved the anatomic and functional assessment of lacrimal apparatus. The methodology allowed in all patients an accurate visualization of the lacrimal system and the identification, in twenty cases, of pathological causes of epiphora. One patient was examined after dacryocystorinostomy. Digital dacryocystography is a very valuable technique for better contrast resolution, the subtraction of images, and continuous acquisition.
