We wished to determine which areas of the visual field contribute most strongly and most frequently to the deterioration of the visual fields in patients with high ocular pressure. The computerized analysis, using linear and multiple regressions of the findings in 382 visual fields, allowed us to select four test points sensitive enough to estimate the actual global sensitivity of the central visual field (correlation coefficient, 0.98). This system also allowed us to estimate the number of pathological points and even to classify accurately over 75% of the cases in terms of their normal or pathological condition, as well as to determine the depth of the defect. The remaining cases show that the deterioration, if it exists, is not significant. Requiring less than 1 min a threshold examination at these four test points enables us to acquire greater insight into the glaucomatous defect.

An evaluation was carried out comparing Oculokinetic Perimetry (O.K.P.) with Automatic Perimetry of Thresholds (Hipocampus Perimeter) for ocular hypertension and glaucoma studying 145 eyes. The O.K.P. shows a sensitivity between 35.65 and 38.54%, a specificity of 76.67-79.59%, a + predictive value of 78.72-85.42%, and a-predictive value of 23.71-39.80%.
