[Documentation of digital dacryocystography using video technique]

Abstract

Digital dacryocystography is considered the optimal radiodiagnostic method in obstructions of the lacrimal pathways. The examination is carried out by a computer-controlled X-ray unit with a C-arc attached to an image-intensifying TV system. In this way the advantages of this technique and of modern video recording are linked. The bilateral filling process of the contrast medium is recorded and the findings simultaneously recorded on videotape. Consequently, pictures of the dynamic flow are retrievable at any time. This provides good diagnostic documentation and an outstanding basis for any scientific analysis.
