is well and widely represented, a fitting trib ute to the breadth and depth of the contribu tion to ophthalmology made by the most emi nent of them all. Each of the contributions are scholarly, thoughtful, timely and well referenced. Clin ical application of new medical, surgical, and pharmacotherapeutic techniques are stressed throughout. It would be in error to single out any one chapter, for each commends itself to the reader by its excellence and practicabil ity. The editor is to be congratulated for cre ating a volume that will help both the generalists and specialists stay abreast of new developments in a wide variety of areas. Staff members and practitioners will enjoy this volume immensely for it contains a wealth of information about ophthalmology and its master. The reader will find just what he desires—if not, he can "look it up in the Duke" ! Marvin L. Sears MODERN

The great problems with which ophthal mologist and ophthalmic surgeon are faced when treating secondary retinal detachments are covered thoroughly in this volume. The authors, who are all world-renown authori ties on retinal disease, present their various views and approaches to the myriad of prob lems which can arise when retinal detach ments occur secondary to trauma, systemic disease, or inflammation. It is somewhat regretable that this volume appeared two years RETINA.

after the meeting took place and, therefore, some of the novelty of many of the tech niques and approaches described in this vol ume has worn off. Nonetheless, the articles summarize lucidly and thoroughly the pres ent state of the art of handling retinal and vitreous problems which evolve secondarily. This volume should be of interest to those who wish to familiarize themselves with the difficulties and problems encountered in treating secondary retinal detachments.

Verriest. Basel, S. Karger, 1972. Clothbound, table of contents, index, 68 black and white figures. $20.75 This book reflects the beginning of a mo ment within ophthalmology—a movement dedicated to the analysis of acquired color deficiencies. Since the rather famous sugges tion made by Helmholtz that congenital color anomalies were possibly reduction forms of normal color vision, great attention has been directed towards daltonism as a means of de fining normal mechanisms by subtraction. Through fundus reflectometry and other fine techniques we have greatly advanced our knowledge of congenital color defects. The results have quite effectively supported Helmholtz's thesis. Most recently, through the efforts of Professors Blackwell, Alpern, Sloan, and others, congenital monochromacy has become far less mysterious. Yet, the very subtle color sense has not been well exploited in acquired color defects. The reasons for this are complex. Our tests and facilities tend to be limited ; we tend to place too much emphasis on the role of the photolabile pig ments and to direct too little concern towards other response levels mediating color vision ; we have often studied disease processes at too advanced a state, etc. Thus, a new move ment concerned with acquired color deficien cies is to be welcomed and encouraged.
