    Eye, Retina - Degeneration in a male F344/N rat from a chronic study. Mild retinal degeneration, featuring loss of rod and cone photoreceptor processes, single-cell necrosis of outer nuclear layer photoreceptor cells, hypocellularity and disorganization of the inner and outer nuclear layers, and narrowing or absence of the plexiform layers.

    Eye, Retina - Degeneration in a male F344/N rat from a chronic study. Marked retinal degeneration, featuring overall thinning, architectural disruption, loss of almost all cellular elements, and complete absence of the rod and cone photoreceptors and the plexiform layers.
