title: Static perimetry: strategies.
abstract: 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) 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.
