Preface to the seventh edition
Eugene Wolff's book has now passed through six editions and ten reprints in less than forty years, growing
in pages from 309 to 553 and in illustrations from 173 (initially none in colour) to 467 (56 in colour). Both
text and illustrations contain much that is of historical interest, and - like my predecessor - I have wished
to avoid tampering unnecessarily with the author's creation. However, very considerable changes have been
necessary which have entailed a rewriting of about a quarter of the text. Only the chapters on the osseous
orbit and comparative anatomy have required less extensive deletions and replacement by new writing. In
all sections many old citations (limited in interest and often undocumented) have been omitted; and yet the
Bibliography has almost doubled in length, a measure of the injection of new contributions. The
accumulations of knowledge, particularly in such fields as the ultrastructural detail of ocular tissues, analysis
of ocular movements, and organization in the visual pathways, have demanded particular attention; and
it is to these that revision has been deliberately directed. These and other fields of study have evoked many
highly specialized monographs and a countless legion of original papers, many of which can only be quoted
briefly. But it is my belief that readers of such a generalized textbook as this will thus find useful signposts
by which to look elsewhere for further detail.
There are 75 new illustrations in this edition, the majority being replacements. In this regard I am much
indebted to my friend, Mr Richard E. M. Moore, DFA(London), MMAA, FRSA, who works in my own
department; he has contributed 28 new illustrations and diagrams. I am also most grateful to Dr John Marshall
and his assistant, Mr P. L. Ansell (both of the Institute of Ophthalmology, University of London), who have
provided much improved substitutes for 40 electron- and photo-micrographs. I must also thank Dr N. A.
Locket (of the same Institute) for the loan of preparations for photomicrography. My colleagues, Mr Kevin
Fitzpatrick and Mr Joe Curtis, have also helped in the replacement of several illustrations. Dr Gordon Ruskell
(The City University, London) has helped with much useful criticism. From the publishing staff, and
particularly Mr John Goodhall, I have received most efficient and patient support. Despite all this help I
am solely responsible for any inaccuracies and omissions in this text. While hoping that readers will find
it improved in its usefulness, I hope equally that they will volunteer their criticisms and suggestions.

Preface to the first edition
This Anatomy of the Eye and Orbit is based mainly on lectures and demonstrations which I have had the honour
to give during ten years as Demonstrator of Anatomy at University College, and for the last three years as
Pathologist and Lecturer in Anatomy to the Royal Westminster Ophthalmic Hospital.
It is an attempt to present to the Student and Ophthalmic Surgeon the essentials of the structure,
development, and comparative anatomy of the visual apparatus in conjunction with some of their clinical
applications. The motor nerves to the eye muscles have received special attention, as have also the
illustrations, many of which are from my own preparations.

Preface
Revision of Eugene Wolff's Anatomy of the Eye and Orbit has been a very considerable task and one which
we have enjoyed. This new edition builds on the strengths of its predecessors while reflecting the increase
·in our knowledge since the seventh edition was published over twenty years ago.
The larger format of this edition permits the use of double columns, and gives far greater flexibility to
the display of illustrations. The text is now over 600 pages long, despite the omission of the chapter on
comparative anatomy. The number of illustrations, many of them with multiple parts, has been increased
to 667, of which 570 are new or have been redrawn. Many of the old figures have been reannotated where
possible, to give a consistency of style.
In order to do justice to the expansion of knowledge of the anatomy of the eye and its related structures,
seven new chapters have been added: the cornea and sclera, the iris, the ciliary body and choroid, the
drainage angle and the lens and the retina have each been given independent status. Although we have
retained parts of the old text, most has been extensively revised. In many respects the book is entirely new;
new topics include: the innervation and classification of the extraocular muscles, the ocular mucins, the
collagens and proteoglycans of the ocular coats, the properties of the trabecular cells, stereology of the lens,
the detailed anatomy of the ocular circulations, the morphology and connectivity of the retinal cells, the
functions of the retinal pigment epithelium and current views on the topography of the visual pathway and
the role of the visual and prestriate cortices.
We are indebted to the many scientists who have provided illustrations for this book and would like to
thank the following individuals, in particular, who were most generous with material and with their time
and advice. They include: M. P. Bergen; M. van Buskirk; M. B. Carpenter; 0. Earley; G. Eisner; A. W.
Fryckowski; T. F. Freddo; I. K. Gipson; I. Grierson; J. Jonas; H. Kolb; L. Koornneef; J. R. Kuszak; D. Landon;
E. Liitjen-Drecoll; N. R. Miller; J. M. Olver; Y. Pouliquen; A. C. Rhoton; G. L. Ruskell; J. Sebag; K. Sellheyer;
B. W. Streeten; E. R. Tamm; G. Vrensen; S. Zeki and E. van der Zypen.
From the inception of this new edition of Wolff's Anatomy, until his death, Roger Warwick, who revised
several previous editions, was a constant source of encouragement and inspiration. We hope that we did
not stray too far from his wishes. We would like to thank our publishers, Chapman and Hall, in particular
Nick Dunton, for their support and forebearance, and also Jane Bryant and Sue Deeley for the copy editing
and project management, respectively.
We are aware that, despite our best efforts, this book has many deficiencies and we welcome the comments
and criticisms of our readers.
