Eye movement impairments in Parkinson's disease: possible role of extradopaminergic mechanisms

BMC Neurology

Table 2 Oculomotor results.

Median values with 5%-95%-ranges. L, latency; G20, gain of reactive saccades (RS) aimed at targets of 20° eccentricity; Vpk, peak velocity of RS with 20° amplitude (obtained by interpolation along the main sequence); N30 and G(N30), number and gain rapidly alternating back and forth gaze shifts during 30s-epoch (AVGS). *, significant differences with respect to CTL (Kruskal-Wallis-ANOVA of groups CTL, PD-DA and PD-DBS-on followed by Mann-Whitney group comparisons, Bonferroni corrected for multiple testing; all cases p < 0.005) except saccade latency of PD-DA vs. CTL (p < 0.01); note that there were no significant differences between PD-DA and PD-DBS-on. ⁺, significant difference (p < 0.05) between PD-DBS-on and PD-DBS-off (Wilcoxon matched pairs); note that PD-DBS-off was not compared to CTL or PD-DA to avoid repeated measurements
