Show Journal of Neuro- Ophlhalmology 20( 2): 146, 2000. Errata In the 19: 3 issue of the Journal of Neuro- Ophthalmology, the article by Lindsay E. Mulhall, Dip App Sc ( Orth), Isla M. Williams, MD, FRACP, and Larry A. Abel, PhD, " Bedside Tests of Saccades After Head Injury," contained a misplaced decimal point in the Discussion. The sentence should have read: " The IRO study ( 1) demonstrated the low self- paced saccade rate was caused by both multiple steps ( 1.493 steps, ± 0.21, control subjects 1.295, +/- 0.14, p = 0.01) and prolonged average fixation time between saccades ( 359.57 msec, +/- 153.53, control subjects 287.71 msec, - H/- 48.35, p = TABLE 2.

In addition, Tables 2 through 5 should have shown "% Errors" and " Saccades in 30 sec" as headings of equal status. The tables, as they should have appeared, are reproduced below. These errors were entirely our own and occurred after the authors' careful page proof review. The publisher apologizes for any inconveniences these errors have caused. TABLE 4.
