The Field Analyzer Primer: Excellent Perimetry
FIFTH EDITION
This book is intended to serve as an introduction to clinical automated perimetry and particularly visual field testing using the Humphrey perimeter.
It has been written as a concise introduction and reference that may be used by busy practitioners and in training programs. Because of its purpose, this primer does not follow the outline of most textbooks. For example, the bare essentials of modern practical perimetry are covered in a very condensed form in Chapter 1. Chapter 2 has been written primarily with residents and optometry students in mind; it describes normal and abnormal visual fields and how visual field testing works.Those who only have time for absolutely basic information may choose just to read Chapter 1 and to refer to the other chapters as the need may arise. We do, however, strongly recommend that you also read Chapter 4. This chapter addresses what we believe to be the single most fertile area for improving clinical perimetry—the management and training of patients and technical staff.
Compared to the 4th edition, the 5th edition has 60% more content. What’s new in the Fifth Edition:
- Expanded material on perimetry basic principles
- Even more practical recommendations for using perimetry in glaucoma management
- Argumentation for more frequent visual field testing in glaucoma patients
- Latest perimetry guidance including SITA Faster
- Updated suggestions for patient education
- A new chapter on using software analysis to facilitate clinical decisions based on a combination of various test and observation data
- More than twice as many citations as the 4th edition

A word from the authors
Writing this 5th edition of the Humphrey primer has reminded us of just how much visual field testing has evolved since the days when we wrote each of the previous editions. The first two editions introduced Humphrey perimetry itself (in 1986) and the internationally-based normative data application we called Statpac (in 1987). The 2002 third edition focused on the then-new SITA testing strategies and the fourth edition in 2012 emphasized the importance of careful patient management during testing. We also have realized that all four of these earlier editions were written primarily for the use of practicing ophthalmologists and optometrists, with little thought given to the needs of young trainees.
