Study: Antioxidants (2008) Protect Trabecular Meshwork in Glaucoma



See more information about glaucoma treatment and information.

An independent study finds that the antioxidants vitamin E and N-acetyl cysteine (NAC) may reduce the progression of glaucoma. Additionally noted is that effectively reducing or even reversing oxidation may facilitate a healing response in the trabecular meshwork or outflow pathway in the eyes of glaucoma patients. A key suspect in the progression of POAG is local oxidative stress. Oxidative free radicals and reactive oxygen species (ROS) are reported to trigger degeneration in the trabecular meshwork, subsequently leading to increases in IOP and glaucoma.

"The finding of a protective effect of vitamin E and N-acetyl cysteine (a key component of glutathione) adds to the growing evidence that antioxidants are beneficial in POAG and are worthy of further investigation." Dr. Yuan He
