The effect of a foveal scotoma on the visual lobe.
One-dimensional visual lobes representing the detectability of a small bright target on an unstructured background were measured at several contrast levels, both with and without an artificial foveal scotoma. The effect of the scotoma on the lobe is shown to be restricted to the area of the retina covered by the scotoma, and detection ability is unaffected outside this area.
