Experience with a number of visual fields has shown that the algorithm used earlier for estimating general depression in glaucomatous visual fields was too conservative. A new, more sophisticated algorithm for calculating diffuse loss has been devised and the results obtained in the evaluation of 20 glaucomatous visual fields were compared with those obtained manually. The new algorithm is less restrictive, yet produces values for diffuse loss which agree well with the empirical estimates (R = 0.97, N = 14). The new diffuse loss index is also compared with the mean defect index (R = 0.77, N = 159), the 18th Bebie curve ranked value (R = 0.87, N = 159), and the previous diffuse loss index (R = 0.98, N = 105). A general discussion of various aspects of diffuse loss is included.
对多个视野的经验表明，早期用于估计青光眼视野中总体缺损的算法过于保守。已设计出一种用于计算弥漫性缺损的更新、更复杂的算法，并将在评估20个青光眼视野时获得的结果与手动获得的结果进行了比较。新算法限制较少，但产生的弥漫性缺损值与经验估计值吻合良好（R = 0.97，N = 14）。还将新的弥漫性缺损指数与平均缺损指数（R = 0.77，N = 159）、第18条贝比曲线排名值（R = 0.87，N = 159）以及先前的弥漫性缺损指数（R = 0.98，N = 105）进行了比较。文中还对弥漫性缺损的各个方面进行了全面讨论。
