COMPUTED-TOMOGRAPHY DACRYOCYSTOGRAPHY

Twenty-one patients with epiphora were examined by conventional dacryo cystography, using Lipiodol as a contrast medium, and CT dacryocystogr aphy, using a water soluble contrast medium. In the latter, the materi al was not introduced under pressure but three or four drops were admi nistered, providing a physiological method of investigation. Subsequen tly, CT dacryocystography provides functional information about lacrim al disorders and is easy to use.
