Suppression scotomata in concomitant strabismus with harmonious anomalous correspondence.
With binocular scotometry it was shown how the peripheral suppression scotoma of the squinting eye in cases of concomitant strabismus with harmonious anomalous correspondence can be split into 2 parts by a vertical prism. The parts are called the rivalry scotoma and the residual scotoma. This observation has not been described earlier.
