Modern trends in perimetry.

Abstract

In this review of perimetry the subject is treated in two main sections. Part I discusses developments, particularly during the last thirty years, in classical clinical perimetry including the topics of kinetic and static perimetry, the use of multiple stimuli and the role of automation and objective techniques. Part II describes the development of various special techniques designed for more specific information about visual function. These include reference to the importance of controlling target illuminance, the value of spatial and temporal summation in perimetry and the use of coloured targets. The paper concludes by emphasizing the clinical value of routine field screening and the urgent need for standardization in perimetry.
