Transmission electron microscopy of the inner plexiform layer.
A: G0 control; B: G1 hypercholesterolemic; C: G2 statins. In G2 (C) features of axon and dendrites necrosis (arrows) were fewer than in G1 (B). In G2 (C) the ultrastructural characteristics of the neuronal processes were more similar to those in G0 than in G1 (B) (A). In G2 (C), Müller cells filled the empty spaces left by necrotic cell processes [Müller cells (M); Müller cell in necrosis (*); G2 (pravastatin)].
