Vitamin C, taken in dosages up to bowel tolerance, is reported to reduce pressure within the eye and restore collagen balance. A vitamin C supplement with bioflavonoids, especially rutin and lutein, are particularly recommended.
There is evidence that marijuana (Cannabis sativa) lowers IOP, as well. Although it is a controlled substance, marijuana can often be prescribed by a professional licensed to treat glaucoma.
Bilberry (Vaccinium sp.) helps maintain collagen balance and prevents the breakdown of vitamin C.
Many people with glaucoma have been shown to have deficiencies of chromium and zinc. Supplementation with these two minerals may, therefore, deter the onset or progression of the disease.
Alpha lipoic acid and other antioxidants may improve visual functioning.
A naturopathic approach called contrast hydrotherapy can be used to stimulate circulation in the eyes. Compresses can be applied over the eyes, alternating three minutes with hot water and one minute with cold water, always ending with the cold.
Biofeedback can be used to reduce the pressure in the eyes by increasing relaxation.
Meditation, stress reduction, t’ai chi, yoga, exercise, and acupuncture also may lower IOP.
Remedies used to lower IOP must be taken continually to avoid optic nerve damage. In addition to other treatments, a glaucoma patient should always remain under the care of an ophthalmologist or optometrist who is licensed to treat glaucoma, so that IOP and optic nerve damage can be monitored.
