• Discriminant analysis using various factors that describe the appearance of the disc has previously separated discs associated with glaucomatous field defects from those without field defects. A prospective study of 36 patients who were classified falsely positive and 36 patients who were true-negative has shown that the incidence of subsequent field loss in the false-positive group was substantially higher than in the negative group. The implications for prediction of patients in whom visual field defects may subsequently develop are discussed.
