Visual Field

Visual field testing is indispensable in diagnosing and managing glaucoma. Over the past 50 years, computerized visual field testing with standard automated perimetry (SAP) has become the standard method for assessing visual function in glaucoma. SAP measures threshold sensitivity at specific test locations of the subject’s retina using white stimuli on a white background and provides a method for estimating visual field abnormalities by comparing these to a normative database. This chapter will briefly describe the historical development of the “field test” and cover important new advances in the technology, technique, and clinical application.
