Involuntary “Voluntary” Nystagmus

Conclusions: The patterns seen in these patients suggest that there is a spectrum of oculomotor saccadic instabilities that includes voluntary nystagmus on one extreme and ocular flutter on the other. In between these 2 are both normal and abnormal patients with eye movements indistinguishable from ocular flutter/voluntary nystagmus that may or may not be induced by convergence. It is suggested that involuntary “voluntary nystagmus” is a real condition and that psychopathology should be ruled in rather than simply assumed.
