Genesis and therapy of dacryocystitis neonatorum
Abstract:
By means of post mortem dacryocystograms and photomicrographs of histological slides, the topography and morphology of the lacrimal ducts in newborn infants are demonstrated. Because of bends in the course of the lower tear duct a percentage of probings will fail to effect satisfactory perforation of Hasner's membrane. In most cases the soft texture of this membrane requires no more than syringing under pressure, using the hollow probe as described by Bangerter (1953).
