Figure 3.
Graphs of iron and isoprostane quantification in the retinas and RPE/choroid of DKO and wild-type eyes with age. Total iron in nanograms per neurosensory retina (A) measured by atomic-absorption spectrometry (AAS) is shown for age and genotype. Total iron in nanograms per RPE/choroid measured by AAS (B) is shown for age and genotype. Isoprostane F2α-VI levels (C) measured by mass spectrometry are shown for 6-month-old DKO in comparison to 6-month-old wild-type neurosensory retinas. *Significant difference (P < 0.05).
