[Problem of scattered light in the localized stimulation of the retina (author's transl)].
In attempting local retinal stimulation of an intact eye the generation of scattered light cannot be prevented, but it can be sufficiently reduced by a suitable selection of stimulus parameters, especially of stimulus luminance and facial field luminance, of stimulus size and exposition time. By investigating the most important sources of scattered light, e.g. inhomogenities in the dioptric media, reflections at refracting surfaces, diffraction at the pupil borders, and the distribution of scattered light in the retina it becomes possible to develop indications for the construction of a focal optical stimulator.
