β¦ Synopsis
After stimulation of the left and right half-fields, it is possible to record contralateral visually evoked neuromagnetic fields (VEF) without any reference to the size of the half-field stimulus display. The test reacts extremely sensitively upon each shifting of the half field into the periphery to the left or right. By application of half-field pattern stimuli of an extremely high or low spatial frequency, characteristic deviation angles are obtained for both the spatial frequencies after evaluation of the VEF amplitudes. By this method the foveal acuity in RP can be investigated with an objective procedure to a very high degree of accuracy.

Retinitis pigmentosa is an inherited progressive disease which is a major cause of blindness in western communities. It can be inherited as an autosomal dominant, autosomal recessive, or X-linked recessive disorder. In the autosomal dominant form (adRP), which comprises about 25% of total cases, app
