Figure 2. Visual performance measured by OptoMotry in bco2−/− mice with and without lutein supplementation.

Figure 2.

Lutein supplementation significantly improves bco2−/− mice’s visual function except for the contrast sensitivity of the rod cells. (a) Photopic spatial frequency; (b) Photopic contrast sensitivity; (c) Scotopic spatial frequency; (d) Scotopic contrast sensitivity. Values indicate means ± SD; 15 mice were used in each group. *, P<0.05; **, P<0.01.
