![. EYE-PARALYSES * BY JOHN AMORY JEFFRIES, M.D. [This paper, which Dr. Jeffries had nearly finished at the time of his death, has been put in my hands to prepare for publica- tion. Although I knew something of his intentions in regard to it, a study of the paper itself and of the mass of material which he had collected on the subject has convinced me of the diffi- culty of completing the task as he would have done it. With the exception of a few verbal changes, I have done little ex- cept to prepare a bibliography from the notes which Dr. Jeffries left, and to indicate in brackets the references to illustrative cases. Not having the original articles at hand and depending almost wholly upon these notes I fear that the classification of the cases, which I have tried to make, is not always correct, and that it might not agree with Dr. Jeffries' greater knowledge. I have added Bleuler's diagram, which Dr. Jeffries had copied, probably with the intention of inserting it. — p. c. k.] Probably every practitioner has at times been in doubt as to the nature of a case of eje-paralysis. The whole question is involved in practical difficulties. A patient complains of double vision; and it is evident, unless the case be one of monocular diplopia, that at least one of the twelve extrinsic muscles of the eyes is paretic. In theory, the changes in the relative posi- tion of the images in different parts of the visual field should lead to an accurate diagnosis; in practice, ow- ing to the complex results produced when a number of muscles are affected, and to the stupidity of patients, the result is often far from satisfactory. Even when the eye distinctly lags in following an object, it may be difficult to determine the condition of the oblique muscles. When, as sometimes happens, the patient fixes with the paretic eye, there is danger that the trouble may be assigned to the wrong eye.
