FIG. 8.

Light-induced destruction of the retinal outer nuclear layer (ONL) can be reduced by the presence of antioxidants. Photomicrographs illustrate changes observed in the ONL (arrow) of the photoreceptor layer progressing from the optic nerve head, which is located at the top right corner of each photomicrograph. Changes were quantified by measuring the ONL thickness of the inferior and superior hemispheres at each defined distance from the optic nerve. The NL thickness of NLD and LD retinas treated with or without the multifunctional JHX-4 or the nutraceutical antioxidant Optixcare EH are to the right of each respective photomicrograph. The JHX-4 data have been previously published³⁵; n=3; mean±SEM.
