| Abstract: | Twenty-one patients with epiphora were examined by conventional dacryocystography, using Lipiodol as a contrast medium, and CT dacryocystography, using a water soluble contrast medium. In the latter, the material was not introduced under pressure but three or four drops were administered, providing a physiological method of investigation. Subsequently, CT dacryocystography provides functional information about lacrimal disorders and is easy to use. |
