Abstract

Two points on the sclera, one in front of and one behind the ora serrata, have been alternately illuminated and the flux densities in the two spots were adjusted until the visual field lit up by the light diffusely transmitted through the sclera maintained a constant brightness as a switch was made from one spot to the other. There was no difference in switching from the first to the second as compared to switching from the second to the first. Schouten and Ornstein who had previously performed a similar experiment found a difference in the two types of alternation, and used their finding as evidence of transmission of an effect through the retina from the ora serrata to the fovea. The present findings support the opposite hypothesis—namely, that the effect is mediated by stray light.
