An accurate assessment of the visual field is of great importance in many neuro-ophthalmologic disorders. Historically, ophthalmologists and optometrists have relied on manual techniques such as the tangent screen and Goldmann kinetic perimeter to map a patient’s peripheral vision. Over the past two decades, automated perimetry (or visual field testing) has increased in popularity and is currently a frequently employed formal method to evaluate a patient’s peripheral vision. Reasons for this change include a more reproducible, standardized test that is readily quantifiable and that provides the opportunity for data storage, statistical analysis, and comparability among patients and offices. In addition, because automated perimetry uses a computer-controlled test algorithm, the role of the physician or technician performing the test may be less demanding in terms of time and training required. The Humphrey perimeter is currently the most widely used automated perimeter in the United States, and example.
