  • Abstract
  • Look Inside

A round plate, with the diameter slightlysmaller than that of the pupil, is placed in front of the human eye.

Then this pupil is illuminated with the electric light across the plate. The pupil con-stricts in response to the light stimulus, but as soon as the pupil constricts smaller than the size of the plate, placed in front of the pupil, the light is cut out by the plate, the pupil dilates again larger than the plate. As long as the pupil is illuminated, this pupil-lary action, repeated constriction and dilata-tion, is continuously repeated and thus indu-ced pupillary oscillation can be observed.
