    Rats exposed to a 12 h lightdark cycle at 32 footcandles show thinning of the outer nuclear layer of the central superior retina midway between the ora ciliaris retinae and the optic nerve. From the normal 12 layers at 6 months of age, the cellularity shows progressive reduction to 10, 8, or 6 nuclei or less by 9, 18, and 24 months, respectively. Parafoveal thinning of the outer nuclear layer follows, before retinal pigment epithelium damage is visible. Careful screening with multiple tests can detect toxic damage before prominent loss of the outer nuclear layer. The pathogenic effect of plaquenil is the induction of lysosomal dysfunction in photoreceptors and retinal pigment epithelium RPE cells. A lysosome is a membrane-bound organelle found in the cytoplasm of most cells and it contains hydrolytic enzymes that function in intracellular digestive processes.
