title: Preventing ambiguity in visual field descriptions.
abstract: Ambiguity in the description of visual fields arises when a field measurement is specified as a number of degrees, without any reference to the measurement as a radius or diameter. Examples of confusing field descriptions in current literature are cited, with a recommendation for improved visual field notation.
