This edition of an already widely read and authoritative teaching volume on perimetry will undoubtedly be as well received as was the first. The author's vast clinical experience adds a special quality to a subject often controversial as to techniques and instrumentation as well as interpretation. He has presented his views without being arbitrary.
The author reverses the usual procedure by doing a tangent screen examination before perimetry. A 2 meter screen is preferred, but he admits that it is generally advisable to start with the 1 meter and then go to the 2 meter screen, when available, for more minute examination of the inner isopters. The simple cloth screen at 1 meter, most generally used in this country, has the advantage of being suitable for smaller rooms. The more wide-spread use of a 2 meter screen is certainly advisable from the reviewer's standpoint, particularly where perimetry is being taught
