T R E A T M E N T OF S T R A B I S M U S . By E u g e n e

Folk, M.D. Springfield, Illinois, Charles C Thomas, 1965. Clothbound, 96 pages, author's preface, index. P r i c e : $5.00. I n today's world of ever-increasing complexity both in available knowledge and in practical application, it is appropriate to stop for a fresh look at the essentials. Occasionally, when these essentials can be sifted out, a relatively clear picture comes into focus. Dr. Folk has sifted the subject of strabismus and gives us in this short treatise some good, practical, clinical suggestions. H e has clearly, and wisely I feel, stated what the treatment of these patients should accomplish : cosmetically straight eyes, good vision in each eye and, if possible, binocular co-operation. H e presents a diagnostic framework which is helpful in evaluating and diagnosing motor defects. T h e recommended treatments for specific findings are clear, definite and no doubt effective. There are items in the text with which we will differ. In general, however, this small book presents a complex problem in a simple, straight-forward manner. It will be rewarding reading for anyone studying or practicing ophthalmology. Paul J. Häuser. R E A D I N G DISORDERS: A
MULTIDISCIPLINARY
SYMPOSIUM. Edited by Richard M. Flower, Ph.D., Helen F . Gofman, M.D., and Lucie I. Lawson, Ph.D., Philadelphia, F . A. Davis Company, 1965. Paperbound, introduction by A. Crawford Bost, M.D., 146 pages, 17 figures in black and white, 5 tables, chapter bibliographies, table of contents, no index. P r i c e : $2.95. These collected papers of a symposium which was held at the University of California San Francisco School of Medicine in 1964, approach reading from a multidisciplinary viewpoint, and the numerous contributors have covered their areas extremely well. T h e chapter on the neurologic aspects of reading disorders is especially well written, and there are many other excellent chapters.
Tt is unfortunate that the chapter on vision is not more complete, in that it does not discuss the role of perception as it relates to visual motor organization and, in turn, as this is related to reading. Although I am well aware that visual abnormalities are only slightly related to reading problems, a discussion of vision and perception would have made the chapter more complete. This book is one that every educator and physician interested in the field of reading should have in his library. H e r m a n K. Goldberg.
CATARACT O P E R A T I O N BY E N Z Y M A T I C Z O N -
ULOLYSIS. By H a n s Hof mann, M.D., N e w York, Grune & Stratton, Inc., 1965. 118 pages, 55 figures in black and white, 2 color plates, 12 tables, bibliography, index. Price : $6.50. This volume of 100 pages is an exhaustive treatise on a small but important phase of ophthalmology. One finds a brief up-todate review of the anatomy of the lens, vitreous and zonule in which all the latest techniques, such as electron microscopy, are discussed. This is followed by a detailed description of the experimental methods used to test the effects of various enzymes on the ocular tissues. There is a most comprehensive review of the enzymes and the effect of temperature, p H , concentration, etc, on theii stability and efficacy. T h e clinical aspects of this investigation include the effect of enzymes on suture material and wound healing, as well as the necessary modifications required in the operative procedure. T h e complications following cataract surgery in 2,500 patients are reviewed and it is the author's opinion that there are no contraindications to the use of enzymes for enzymatic zonulolysis except in children. This is a well-written, fully documented volume. It should prove to be an excellent source of reference material for those oph thalmologists with academic interests. P. Robb McDonald
