Optokinetic asymmetry in internuclear ophthalmoplegia.

The reeognltlon of internuelear oph­ thalmoplegla in patients In whom there is full range of adduetion rests on the "dys­ metria test" and the "optokinetie test." 80th the dysmetria present wlth rapid re­ fixations and the optokinetle asymmetry are diseussed in terms of the neuro­ physiologie mechanlsm behind the slow addueting saeeades in internuelear oph­ thalmoplegla.
