Daroff_04-7 See-saw Nystagmus

Identifier: Daroff_04-7 Title: See-saw Nystagmus Subject: See-saw Nystagmus; Seesaw Nystagmus Description: Two patients with see-saw nystagmus are presented. The nystagmus is usually due to a suprasellar lesion associated with a bitemporal hemianopsia or a rostral midbrain lesion. The nystagmus is conjugate and torsional with a dissociated vertical vector so that the intorting eye rises and the extorting eye falls. Rare examples of congenital see-saw have a reverse relationship between the torsion and vertical movements.
