This is part of a series of guides aimed at students and healthcare specialists in many disciplines. It may be used as as an aide memoire before examinations, or a quick reference to be carried in the pocket. Each pair of facing pages of this pocket sized book contains a collection of six 2” × 2” photographs supported by brief notes indicating the salient features of the conditions illustrated. The photographs are of excellent quality and content (one or two are a little small to do them full justice) and some may be familiar to readers of the author’s other publications. The text notes are brief, but offer the reader a concise and clear classification of the diverse groups of conditions featured without being able to provide the amount of information an ophthalmologist would probably be seeking. There is not, either, a corresponding illustration for each condition described in the text. There is an index to facilitate quick reference. Readers will not be disappointed at the quality of the photography, and the undergraduate will find the text a good summary. The ophthalmologist would probably expect more to stretch him/her if using this as a revision aid.
