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.
我们希望确定视野的哪些区域对高眼压患者视野恶化的影响最为强烈和频繁。通过对382个视野的检查结果进行线性和多元回归分析的计算机化分析，我们得以选择四个足够敏感的测试点，以估计中央视野的实际整体敏感度（相关系数为0.98）。该系统还使我们能够估计病理点的数量，甚至能准确地将超过75%的病例按正常或病理状况进行分类，并确定缺损的深度。其余病例表明，即使存在恶化情况，也并不显著。在这四个测试点进行阈值检查所需时间不到1分钟，这使我们能够更深入地了解青光眼性缺损。
