[Retracted] Biomolecular Modulation of Neurodegenerative Events during Ageing

Figure 1

Morphology of the retina and optic nerve head stained with haematoxylin-eosin. (a) Section of the optic nerve head of a young rat with no obvious abnormalities (6 months, negative control). (b) Section of the optic nerve head of an untreated aged rat (24 months, positive control). The main alteration it was possible to highlight was the increased excavation of the optic nerve head. (c) Section of the optic nerve head of an aged rat after oral supplementation with α-lipoic acid (ALA) and superoxide dismutase (SOD) (24 months, positive control). Here, a smaller papillary excavation and a good columnar shape typical of astrocyte cells were highlighted compared to the section in panel (b).
