title: Digital subtraction macrodacryocystography by videotechnique.
abstract: Digital subtraction macrodacryocystography (DSMD) has proved to be the best imaging method for diagnosing situations of stenosis of the lacrimal system. The examination is performed with a computer-controlled X-ray unit with a C-arc coupled to an image intensifier TV system with a fluoroscopic control. All the findings were recorded on videotape thus allowing good dynamic flow documentation and contributing to improved scientific analysis.
