Abstract
Photo-stress by focal light bleaches the retina and temporarily reduced retinal function. Recovery from suppression is measurable by monocular and binocular endpoints, when recovery is prolonged a disease is suspected. The monocular endpoint is the moment the dark central afterimage representing the macula becomes the same brightness as the peripheral ring representing unstimulated retina and the binocular endpoint is brightness equality of rivalrous stimuli. Four embodiments are described for measuring relative brightness sense photo-stress utilizing monocular and binocular methodology.
