It has been said that one should be a good general man in order to be a competent specialist. This is especially true in regard to ophthalmic therapeutics. Many systemic diseases have eye symptoms and pathology. The same blood and lymph that nourishes and bathes different parts of the body, also circulates in the structures of the eye. In the examination of the eye, heredity, occupation and environment are to be taken into consideration. Osteopathic lesions may exist from falls, strains, twists, blows, colds and exposure and impair the integrity of the metabolic processes of the eye through the nerve connections and blood supply and lay the foundation for a great variety of eye diseases. With these lesions existing about the neck and upper dorsal, it is only required to have some insignificant local irritant to start symptoms and cause pathology apparently out of all proportion to the etiology. It is important then that one understand the nerve centers and reflexes and the osteopathic logic underlying these conditions or else he must frequently work without a satisfactory explanation of the etiology and consequently be more or less unscientific in his treatment. The eye examination should consist of the case history, the family history, inspection, osteopathic examination, especially from the fourth dorsal vertebra to the occiput and especial examination of the eye by inspection and other methods. =1. The Case History.=—Thoroughness of the doctor, or the lack of it, will be readily displayed at this point. Every little thing, as far as possible, that has a bearing on the case should be observed and uncovered in the case history. The physician should want to know every fact that helps him to better understand his case. Patience in hearing the history will often be of great assistance. It gives light on the physical and mental condition of the patient. Much can be gained by being careful and attentive. Notice carefully what he emphasizes and what he thinks is the most important. Inquire in regard to headaches, nervous symptoms, previous eye trouble and past illnesses. Get a venereal history if present, as many eye diseases are complicated or caused by syphilis or gonorrhea. =2. The Family History.=—Inquire as to blindness in the family and about the age it occurred, if any. Get a venereal history if possible.
