39,876 professional women aged 45 or more took 600 IU of vitamin E every other day and 100 mg of aspirin every day in the 10-year randomized, controlled Women's Health Study (WHS). Women who took vitamin E supplements had rates of cataract development comparable with women who did not take such supplements.

A study led by Tien Yin Wong, MD, PhD examined the correlation between eyesight and mortality. The study assessed 1,232 Chinese people living in Singapore, 10% of whom died; in this group, the death rate was found to be three times higher for people with 20/40 vision.

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 of a study 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.
