متن کاملInternuclear ophthalmoplegia associated with transient torsional nystagmus.
The association of internuclear ophthalmoplegia (INO) with torsional nystagmus is rare. We report the case of a 63-year-old man presenting with sudden onset of diplopia. On ocular examination, he had left INO and a torsional nystagmus with counter-clockwise quick-phases from the patient's point of view in the primary position, ipsiversive to the side of the medical longitudinal fasciculus (MLF)...
