Retinal carotenoids in WT and Bco2^−/− mice subjected to OIR where the nursing mother along with her pups were fed with L, Z, or placebo diets starting at postnatal day 1 (P1) and killed on P17. Retinal carotenoids were never detectable in WT mice. Values indicate means ± SD for three batches of eight pooled eyes for each subgroup. ND, not detectable. **P < 0.01 compared to the placebo-fed group and to the WT controls.
