Typical roving eye movements (pendular deviations of the bulbi) were observed in a 41-year-old patient with bilateral symmetrical softenings in the anterior thalamic region. They constantly appeared after lid closure with a mean latency of 7.3 sec. The mean frequency was 0.25 cps, the mean amplitude 30 degrees. The phenomenon of roving eye movement is discussed with regard to the supranuclear structures regulating binocular eye movements.
