Color external photograph shows Kayser-Fleischer ring (arrows), a golden-brown discoloration of the cornea due to deposition of sulfur-copper complexes within the Descemet’s membrane. B: T2-weighted MRIs reveal symmetrical high signal intensity lesions in the putamina, thalami, midbrain and pontine tegmentum. C: Video-oculographic recording (SMI®, Teltow, Germany) of saccades shows selective slowing of downward saccades while the velocities of horizontal and upward saccades are normal. D: Smooth pursuit is impaired in the vertical direction. LH: horizontal position of the left eye, LV: vertical position of the left eye.
