There has been a general revision of Traquair's book, which first appeared in 1927, and eighteen new illustrations have been added. This edition follows the form of the three previous editions in that the first part contains chapters on normal fields, methods of examination and instruments available for field studies. In part II the author gives illustrations of typical fields, anatomy of the visual pathways and illustrative cases with fields demonstrating interruptions at various levels. There are special chapters on diseases of the choroid and retina, glaucoma, optic nerve diseases, the optic chiasm, the suprachiasmal pathway and functional changes in the fields of vision. In the appendix he presents isopters for white and color in the normal field; the blind spot; anatomic relations of the visual pathway; the optic nerve sheaths; blood supply of the visual nerve path, other uses of the perimeter and a table of tangents for use
