[Objective determination of visual acuity using electronystagmography-recent experiences].

After slight modification of an electronystagmograph (Jung) an objective estimation of visual acuity was carried out. The optokinetic nystagmus was inhibited by a variable light spot, which was projected in the middle of the screen (Ohm's method). In 95 (161 eyes) of 98 patients the suspected simulation or aggravation was verified.
