From the Women's Health Study (WHS) it was determined that women who took vitamin E supplements had rates of cataract development comparable with women who did not take such supplements.

Evidence has been found to support the theory that low cerebrospinal fluid (CSF) pressure may be a significant contributor to optic nerve damage in glaucoma. Results showed that between 1996 and 2007, 28 patients with primary open-angle glaucoma who had CSF samples taken by lumbar punctures had significantly lower pressure than controls.
