Videodocumentation in digital dacryocystography

Abstract

The digital dacryocystography proved to be the optimum method of X-ray diagnostics in obstructions of the lacrimal pathways. The examination was performed with a computer controlled X-ray unit with a C-arc coupled to an image intensifier tv-system. In the study the advantages of this technique were combined with the advantages of modern videotechnique. A nonionic water soluble contrast medium was used. The bilateral contrast medium filling process was registrated and the findings were recorded on videotape concurrently. The videocassettes, marked with the data of the patients and the date of examination, are stored in a video-tape library. This provides an always repeatable diagnostic documentation and it is also an excellent base for scientific analyses. The technique and the results of the examinations, performed with 18 patients, are described.
