Figure 1.

Vestibulo-ocular reflex gain plotted against refractive error for right- and leftwards head impulses. Every symbol represents the VOR gain of one subject calculated by the EyeSeeCam system. VOR gain did not differ significantly between the groups (spectacles, contact lenses, control group). No statistically significant correlation was found between VOR gain and different Diopter in both the spectacles group and contact lenses group for rightwards and leftwards head rotations. The regression line shows a tendency of positive relation between refractive error and VOR gain, but the difference is negligible and has no clinical significance.
