Abstract

Electroretinography (ERG) can be used to quantify the directional sensitivity of the retina to incident stimuli. We have developed a rapid technique to derive a global measurement of the Stiles-Crawford effect of the first kind (SCE I) using the full-field flash ERG using artificial pupils. Three opaque haptic contact lenses were designed to direct stimuli along the photoreceptor axes with a single central aperture or obliquely through double apertures of equivalent area (4.5 mm2) separated horizontally by 3.0 and by 5.5 mm.
