Treatment of Lachrymal Obstruction

In affections of the lachrymal sac the rhinologist may be called in to ascertain whether there is any predisposing cause in the nose and to treat this if found, or to treat the condition of the sac when this involves manipulations in an area with which he is familiar. There is close relationship between the lachrymal sac and the nasal cavity, in addition to direct communication through the tear duct, and although ascending infection from the nose may to some extent be prevented by folds of mucous membrane (so-called valves), yet, on account of this close relationship, affections of the sac are not infrequently found to be of nasal origin.
