Electrophysiology of Vision: Clinical Testing and Applications

Byron L. Lam, MD. Taylor and Francis Group, Boca Raton, FL, 2005. ISBN: 0-8247-4068-8, $149.95.

Scope: This book provides a clinical approach to the methods and interpretation of visual electrophysiologic testing.

The first section of this book is a summary of essential features and practical tips on performing visual evoked potentials (VEPs); full-field, focal, multifocal, and pattern electroretinograms (ERGs); and electro-oculograms (EOGs). The physiologic effects of maturation and aging on the interpretation of these tests are also highlighted.

The second section of this book outlines symptoms and signs of various ophthalmic diseases with pathognomonic visual electrophysiologic abnormalities. The book covers a range of conditions, including optic nerve and other visual pathway disorders, genetic, inflammatory, vascular, nutritional, and toxic retinopathies, pharmacologic effects, and non-organic visual loss.

Strengths: This comprehensive, yet concise, review of the clinical applications of electrophysiologic testing in ocular disorders offers very practical and useful information that is required in the diagnosis and management of patients. The writing style is clear with enough tables and photographs for easy understanding of the topic.

Weaknesses: As with any book, some material may quickly become dated. Because of the rapidly emerging advances in focal and multifocal evoked potentials and electroretinography, these aspects may require updating in 5 years.

Recommended Audience: Caregivers who examine patients with visual pathway disorders and those interested in improving their knowledge of the application of VEPs, ERGs, and EOGs will benefit from reading this book.

Critical Appraisal: This is one of the few practically oriented books in visual electrophysiology that is not only enjoyable to read but useful in the clinical setting.
