Tarek Shaarawy, Mark Sherwood, Roger Hitchings, and Jonathan Crowston have coedited a masterful new 2-volume text on the diagnosis and therapy of glaucoma. Volume 1, Medical Diagnosis and Therapy, covers the old and new in medical diagnosis and therapy and does so in a through and careful manner. All such texts are prepared by committee, with individual topics assigned to experts. One major advantage in this particular iteration is that despite the diverse authors, the chapters are coherently edited. The editors have insisted on tables and flowcharts in addition to the voluminous photographs always used to illustrate such texts, allowing for reinforcement of the major and salient points the authors and editors wish to emphasize. In addition to covering some of the more historical aspects of glaucoma—for example, Koeppe gonioscopy lenses are fully documented, although I did not find anything on dipifevrin—the text likewise provides careful reviews on the economics of glaucoma care, the Ocular Hypertensive Treatment Study, and the role of measuring central corneal thickness. Much effort is spent discussing optic nerve imaging modalities, allowing the relative novice a chance to understand the strengths and weaknesses of these somewhat newer technologies.
