A technique that helps flush the lacrimal sac with narrowing of the lacrimal passages
Friede (Zeitschr. F. Aug. 1928. Bd. 65) offers a simple technique to help flush the lacrimal sac with narrowing of the lacrimal passages, when the latter fails due to the fact that the fluid returns back through the superior lacrimal canal. F. recommends in such cases, introducing fluid through the lower tubule, to squeeze the upper tubule using a round glass rod placed over the lacrimal meatus, while pulling it at the same time to the nasal process of the upper jaw. Thus, the possibility of reverse flow of the liquid is eliminated and it goes in the right direction.
