Please read our "Eye problems" article to educate yourself on Glaucoma. I would recommend your mother perform the Full Body Cleanse and drink herbal tea of bilberry, eyebright, and/or calendula. All of them are good! Drink as much of these teas as possible while detoxing. After detoxing, have her keep drinking the teas and to take dherbs.com Eye Formula and the Circulation Aid formula.
