† Consistent with the literature value for rat vitreous, 2.3±0.4 μm2/ms [13] Statistically similar value in all four cases (two-way repeated measures ANOVA; F [1,7] <3.20 and p>0.11 for both main effects and interaction). ‡ Statistically similar value in all four cases (two-way repeated measures ANOVA; F [1,7] <3.20 and p>0.056 for both main effects and interaction). ** Statistically similar location in all four cases (two-way repeated measures ANOVA; F [1,7] <0.56 and p>0.47 for both main effects and interaction). * A main effect of direction (┴ > ║; F [1,7]=9.76, p=0.017), but neither a significant effect of dark versus light nor an interaction (F [1,7] <3.99 and p>0.085) was found with two-way repeated measures ANOVA. aA main effect of direction (┴ > ║; F [1,7]=9.90, p=0.016), but neither a significant effect of dark versus light nor an interaction (F [1,7] <0.43 and p>0.53) was found with two-way repeated measures ANOVA. bStatistically similar location for light and dark data (p=0.41; paired two-tailed t test). cStatistically similar location for light and dark data (p=0.65; paired two-tailed t test).
