Normal Variation in the Stiles-Crawford Effect Peak Location and Rho value*

Abstract

At the Topical Meeting on the Noninvasive Assessment of the Visual System January 26-28, 1987 at Incline Village, Nevada, we presented normative data on the foveal Stiles-Crawford effect (SCE) peak location for the largest sample of single eyes for single individuals ever tested and compared our results to those of other studies reported in the literature1. In this paper we honor the 60th anniversary of the discovery of the SCE2 by extending our analysis to include SCE rho (ρ) values and a more extensive comparison of our results to results reported in the literature.
