Dynamic documentation of digital dacryocystography

Ophthalmic Surg. 1993 Aug;24(8):556-9.


Digital dacryocystography has proved to be the optimum method of x-ray diagnostics in connection with managing obstructions of the lacrimal pathways. We present 50 patients in whom digital dacryocystography was performed with a computer-controlled x-ray unit and a C-arc coupled to an image intensifier TV-system. A nonionic water soluble contrast medium was used. The bilateral contrast medium filling process appearing on the monitor was simultaneously recorded on videotape. Videocassettes, with patient data attached, were stored in a videotape library, providing repeatable diagnostic documentation and an excellent base for scientific analyses.
