title: Visual images observed following an enucleation.
abstract: After enucleation of the right eye the author observed persistent and continuous visual images featuring angular groups of parallel-line segments which have continued for two years, to the present time, though considerably diminished. These phenomena are reported along with results of measurements of the images and of several simple experiments. Some quantitative comparisions are made to results from studies of macaque monkeys, and to human migraine fortification images.
