the orbit. Illustrative cases and superb illus­trations of the surgical techniques that are pertinent enrich the carefully written text.

There are four tables of differential di­agnosis covering (1 ) lid tumors, (2 ) con-junctival tumors, (3 ) distinguishing fea­tures of pseudoglioma and retinoblastoma, and (4) orbital masses. These are among the most informative features of the book, and evidence much thought and experience. I am sure that most of the readers will con­sider them to be very sound.

This is truly a most commendable book. Derrick Vail.

STRABISMUS: Symposium of the New Or­leans Academy of Ophthalmology. Edited by George M. Haik, M.D. St. Louis, Mosby, 1962. 354 pages, 201 illustrations, round-table discussions and index. Price: $18.00. The published symposiums on a variety of

selected subjects of the annual meetings of the New Orleans Academy of Ophthalmol­ogy have been interesting and valuable con­tributions to our literature. Not the least of these is the book here presented. I t consists of the writings and discussions of the "muscle men" presented at the 11th annual session of the academy and edited by George M. Haik.

The participants are R. N . Berke, H . W . Brown, D. G. Cogan, J. W. Henderson (Ann Arbor ) , A. Jampolsky and M. M. Parks, prominent names in this difficult field.

Parks discusses the etiologic and compen­satory factors of comitant horizontal devia­tions in children, and goes on to elaborate his interpretations of eso- and exodeviations.

Henderson skilfully covers the difficult sub­jects of the neuroanatomy of ocular motility and amblyopia.

Cogan, deep student of the thorny problem of ocular nystagmus, helps to clarify this sub­ject for us.

Jampolsky lectures on the management of small-degree esodeviations and exodeviations,

and gives us a good chapter on the A and V syndromes.

Berke shares his wide experience and sound judgment on the surgical treatment of horizontal and vertical squint in two excellent chapters.

Brown, one of the old-timers with modern outlook, helps us in understanding the com­plexity of the problem of strabismus in the adult, and then makes us feel a little better by his discussion of the complications that (sometimes) occur after squint surgery.

The round-table discussions make the best feature of this valuable and timely book. The informality and the frankness of the verbatim reports are refreshing, and the information squeezed out of the participants is frequently most elucidating.

To write a lucid paper on the complex and still not too well-known subject of strabismus is one of the most difficult arts in ophthalmol­ogy. To read and understand such a paper is also a difficult study. I t is very easy for both writer and reader to get lost in the maze, bogged down with verbiage. One naturally, therefore, encounters this same difficulty in communication between writer and reader in this book. In spots it is hard going, but the reader will be adequately repaid by most care­ful study and restudy, in spite of the fact that some of the writers lapse at times into the language and phraseology of bureaucrats.

The American school of ocular motility, if this is the correct term, has had a world-wide influence. No doubt this volume will bring further credit to the "school."
