Localization of injected FITC-Aβ42. (a) Retinal section from an experimental eye treated with FITC-labelled Aβ42 fibrils (green fluorescence) 2 days after injection. (b) Corresponding retinal section from the control eye. (c) Signal noted 14 days after the injection in the experimental eye, but not in the control eye (d). Results were replicated in six rats in each subgroup. Scale bars: 40 µm.
