在静态视野检查中，极限法被广泛用于阈值确定。它的性能进行比较的楼梯方法（重复上下方法）的一定修改的模拟装置，其中的行为的观察员所描述的一个假设的心理功能。系统误差和随机误差在升降法中要小得多。进一步考虑信号检测理论和最优策略的概念。
In static perimetry the method of limits is widely used for threshold determinations. Its performance is compared with that of a certain modification of the staircase method (repetitive up and down method) by means of simulations, where the behaviour of the observer is described by an assumed psychometric function. Systematic and random errors are considerably smaller with the up and down method. Further consideration is given to signal detection theory and to the concept of optimal strategy.
