    EXTERNAL DISEASES OF THE EYE. EXAMINATION OF THE EYE IN DISEASE. In ophthalmology, as in other fields of medical activity, success in diagnosis depends, above all, upon the expe- rience of the diagnostician. Only second in importance, however, is a definite, systematic routine in examination, the faithful observance of which will eventually become second nature to the surgeon, so that he will almost in- stinctively apjdy all the various methods of examination one after the other in their pro|)er order. Owing to the ease with which both the exterior and the interior of the eyeball can be seen, the great majority of its external as well as its internal alterations and disea.ses can be determined with absolute certainty, usually at the first examination. Those ca.ses in which the diagnosis mu.st be confirm(‘d or corrected by observing the course of the disease or the effect of treatment («r jumntihu.s) form a small minority ; and in only a verv few disease- processes is the true intcrj)retatiou obtained from the autopsy. The o]ihthalmic surgeon is rarely forced to conclude his diagnosis with the ]ihrase “ .secif/o docehif ” —a virtual admi.ssion of failure. Nevertheless the practice of ophthalmology, if based on the ])roper recognition of disease, is by no means without its difficulties. The physician is confronted and perhaps misled by a multitude of processes differing but slightly from each other, by a rich variety of clinical pictures, and by the difficulty of recognizing many im- ))ortaut pathologic conditions in the eye, either bec^ause the lesions to be looked for are very small or because they are apparently unim))ortant—that is, they jjresent well-nigh imperceptible deviations from the normal.
