That the nose and its pathology have a direct influence on the health and function of the eyes has long been admitted, and the more obvious and striking forms of interdependent diseases have for a long period been recognized and treated.
It is unnecessary to mention the ordinary examples of associated disease. I wish to call your attention to a practically unrecognized condition. The symptoms of this condition are purely ocular. The patient never has a reason to suspect a nasal origin, and, as use of the eyes almost invariably increases the headache of this condition, he consults an oculist for relief. Another reason for believing that the eyes are at fault is that correct glasses relieve for a time all or the greater part of the symptoms. This may be explained by the lessened congestion of the ciliary body resulting from a relief of eyestrain, however small in amount.
