[Perimetry in chiasmal syndrome -Liminal and surpraliminal stimuli (author's transl)].

The value of static and kinetic perimetry with white and colored stimuli in chiasmal syndrome seems to be equal. The presentation of evenly moving supraliminal targets allows for an evaluation of sensory disturbance. This procedure is even more subjective, variable and difficult to perform accurately. It may reveal, however, more discrete sensory pathology than conventional perimetry can do. Red is often better than other colors, spectral colors are better than pigment colors. The sector-shaped pattern of disturbance of sensation might relfect the arrangement of nerve-fibers in the optic chiasm.
