Quantitative layer-by-layer perimetry adapted to the Humphrey Field Analyzer. III. Centre-surround interaction produced by transient surround stimulation. Area characteristics of the transient stimulus pattern.
In this paper some qualitative aspects of centre-surround interaction produced by transient surround stimulation are investigated, employing a new design of quantitative layer-by-layer perimetry. Using a rotating windmill pattern, a transient response, believed to be organized in the inner plexiform layer of the retina, is assessed in four normal individuals. The paper considers area characteristics of the stimulus pattern used to produce the transient response, and optimal dimensions for this pattern are proposed.
