Comparison of Spatial Summation and Threshold versus Retinal Eccentricity Functions in Normal and Deuteranopic Observers

Abstract

Spatial summation functions were determined for three deuteranopes and three age-matched normal trichromats under stimulus conditions which favored stimulation of the long-wavelength receptor system. No differences were found in the data of two groups suggesting that some modification of existing threshold models is necessary.
