The highlights of this edition are ? latest medical and surgical management of some diseases, and updates on newer investigations. The new look and the use of American spelling make the book reach out to a wider range of international readers. However, a few things have not changed in this edition, like its predecessors, plenty of diagrams and photographs are in four color. The bulleted format of the book, detailed illustrations, a selection of slit-lamp examination, and such features which facilitate revision have been retained.
