Our object in this paper is to discuss methods of examination of the visual fields, to emphasize the value of graphic records, and to stimulate neurologic interest in an ophthalmologic field, as well as to present in outline certain clinical cases. Knowledge of the physiology of vision and its relation to the anatomy of visual pathways has been established on a sound and eminently practical basis. Lesions interrupting different parts of the visual tracts can frequently be localized with almost mathematical accuracy. This can be accomplished, however, only by means of accurate observations, which in turn depend on the use of methods of precision. Notwithstanding the immense value of visual field examination as an aid to neurologic diagnosis, careful routine work in this line is being done only by a few enthusiasts. In theory, the charting of the visual field is relatively simple, but in clinical practice many difficulties are
