Radiological and histological findings of the lacrimal passages of newborns
H. Busse, K. M. Muller and P. Kroll
By means of postmortem dacryocystograms and photomicrographs of
histological slides, the topography and morphology of the lacrimal passages
in premature and mature newborn infants are demonstrated. Because of the
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 a hollow probe.
