Figure 2. OKR characterized the effect of the occ mutation on saccades.

Figure 2.

The number of saccades in the occ mutant was significantly lower compared to those in wt. At 4 to 5dpf, the number of saccade eye movements per 20 seconds in wt was 12.2 ± 1.9 and only 8.9 ± 2.3 in occ. Only one day later, at 5 to 6dpf, the number of saccades in wt increased to 17.4 ± 1.5 but decreased to 6.4 ± 2.5 in occ, indicating poorer optical function in the mutant. Data were expressed as the mean ± SD. The differences between groups were significant at P < 0.05.
