REGRESSION ANALYSIS OF THE CENTRAL VISUAL FIELD IN CHRONIC GLAUCOMA CASES

Abstract

Glaucoma patients (90) (160 eyes) with field defects in at least 1 eye were subjected to automatic perimetry on at least 5 occasions. The condition of the fields is summarized in single numbers. Regression analysis was applied to series of such performance numbers. The trend of the development of the field defect is represented by the regression coefficient. The frequency distribution of the coefficients in groups based on references to age, sex, intraocular pressure, exfoliations, hemorrhages and therapy illustrates the possible importance or insignificance of these factors to the decay. The need for several consecutive examinations to establish with some significance a progression of field defects is demonstrated.
