Abstract

Perimetry is a useful tool for monitoring the health and integrity of the retina and associated higher visual processes but as commonly used, is a rather poor predictor of visual function. Only a few efforts have been made at rectifying this shortcoming (Esterman, 1967, 1968, 1982). As we reported at ARVO this spring (Arditi and Faye, 1986), defining the functional field requires consideration of both the spatial consequences of having two monocular field maps with different but overlapping views of space and the demands on that binocular field of specific visual tasks. This paper discusses the geometric analysis of the normal and impaired visual fields and the consequences of retinal field defect location on space perception. We also present a method for functional analysis of visual fields using an automated perimeter and a microcomputer.
