Multivariate analysis in glaucoma. Use of discriminant analysis in predicting glaucomatous visual field damage.

A discriminant function obtained in 1978 to separate patients with glaucomatous visual field loss from those without visual field loss was shown to have a predictive value in ocular hypertensive persons as to the subsequent development of visual field loss in five years. A prospective discriminant analysis also was carried out to identify those factors that best separate those in whom visual field defects developed from those in whom they did not.
