Quantification of eye pigment and phosphorylated Tau a Pigment level as a quantitative measure for eye degeneration: Levels of pigment were determined according to a formula shown in “Materials and methods” (number of heads = 15, 3–5 repeats). b Levels of total and phosphorylated Tau in eye tissue determined by western blotting (left), and calculated ratios from densitometry of the blots (right). Student’s t test analysis showed **p < 0.05, ***p < 0.01
