title: Photographic measurements of retinal blood oxygen saturation: falling saturation rabbit experiments.
abstract: A noninvasive photographic method of measuring retinal blood oxygen saturation and arteriovenous oxygen difference was developed and calibrated on rabbits. The experiments reported show that the accuracy of the measurements made using the method is better than 1.0 per cent. The method is applicable to vessels located anywhere in the fundus and represents a significant improvement over previous methods.
