Most ophthalmologists agree that accurate perimetry is indispensable in the diagnosis and management of ocular disorders, especially glaucoma and neuro-ophthalmologic diseases. Sloppy examination of the visual field may suggest a wrong diagnosis or provide the ophthalmologist with a false sense of well-being while his patient's vision deteriorates. Unfortunately, skillful perimetry is all too uncommon in many office practices. Visual field testing is often relegated to unskilled technicians who lack interest, use uncalibrated or inaccurate equipment, or conduct hasty and undirected examinations. Ophthalmologists often lack sufficient knowledge of theoretical and practical aspects of perimetry.
The major goal of this new perimetric technique textbook is to upgrade the quality of visual field testing in the practitioner's office. The first part of the book, which is clearly directed at the ophthalmologist, considers in some detail the theoretical basis of perimetry. A long chapter, which constitutes nearly one fourth of the book, deals with
