Does Low Selenium Contribute to Pseudoexfoliation Syndrome?

December 26, 2010

Pseudoexfoliation syndrome occurs when a flaky, dandruff-like material peels off the outer layer of the lens of the eye, and clogs the eye’s drainage system. This clogging can increase eye pressure and lead to glaucoma.

A recent study investigated the levels of selenium in the aqueous humor, conjunctival specimens, and serum of patients with pseudoexfoliation (PEX) syndrome, and a control group.

The study found that patients with PEX syndrome had significantly lower mean selenium levels in their aqueous humor and conjunctival specimens. Researchers suggested that reduced levels of selenium may impair antioxidant defenses in the eye.
