D., PROFESSOR OF DISEASES OF THE EYE AND EAR IN THE NEW YORK POST-GRADUATE MEDICAL SCHOOL ; SURGEON TO THE MANHATTAN EYE AND EAR HOSPITAL. We are at least making' some advance in our knowledge of the true place of abnormal ocular conditions in the causation of disease when the statements so widely made in this country only a few years ago, that they were the real causes of most of the neuroses, are pretty generally aban- doned. The most that is now contended for by the authori- ties who attach a high importance to the want of equi- librium of the ocular muscles is that they produce a set or series of symptoms limited to the eyeballs, the lacrymal passages, the orbits, and the head, and comprehended un- der the term asthenopia. As is well known to the readers of the New York Medical Journal, it is my belief that in the refractive condition of the eyes will be found the source of any insufficiency, or of any want of equilibrium of the muscles of the eyeball, and that we must logically seek for relief by modifying the influence of the cause—that is to Copyright, 1891, by D.
