The mechanism and clinical significance of optokinetic nystagmus.
Observation of optokinetic nystagmus may be of invaluable help in the diagnosis of lesions of the vestibular pathways at all levels from the labyrinth to the cerebral cortex and facilities for its observation are an essential item of modern otological equipment. The majority of the disorders that had been discussed can be recognized on clinical examination with the use of a small optokinetic drum with mechanically or electronically controlled speeds (Table I). In certain cases electro-nystagmographic records may provide further and more precise information.
