Keto Diet Preserves Retina (IMAGE) Society for Neuroscience Caption A ketogenic diet preserves structure of retinal ganglion cells and their connections to the brain. Top (up): Retinal cells are more numerous in the ketogenic diet group (right). These cells were protected by the diet. Scale bar=500μm. Top (down): High magnification insets of retinal cells. Scale bar=50μm. Bottom (up): Optic nerve axons are protected from degeneration in the ketogenic diet group (right). Scale bar=100μm. Bottom (down): Magnified view of insets from optic nerve cross-sections. Scale bar=0.25μm.
