The recognition of internuclear ophthalmoplegia in patients in whom there is full range of adduction rests on the "dysmetria test" and the "optokinetic test." Both the dysmetria present with rapid refixations and the optokinetic asymmetry are discussed in terms of the neurophysiologic mechanism behind the slow adducting saccades in internuclear ophthalmoplegia.
