title: Quantitative layer-by-layer perimetry adapted to the Humphrey Field Analyzer. II. Centre-surround interaction produced by sustained surround stimulation.
abstract: In this paper the practical applicability of a new design of quantitative layer-by-layer perimetry is confirmed by studying centre-surround interaction produced by sustained surround stimulation in preliminary trials on four normal individuals. The results are discussed in relation to established laws for retinal light perception, and some practical aspects of the employed test design and the chosen test variables are discussed.
