Alternative medicine may be defined as non-standard, unconventional treatments for glaucoma.
Use of alternative medicine continues to increase, although it must be noted that some of these treatment alternatives have no proven clinical effect.
Regular exercise and relaxation techniques can be beneficial for lowering eye pressure and may have a positive impact on your overall health and other glaucoma risk factors including high blood pressure.
Always talk to your doctor before starting any alternative therapies.
Proponents of homeopathic medicine believe that symptoms represent the body’s attack against disease, and that substances which induce the symptoms of a particular disease or diseases can help the body ward off illness.
The Food and Drug Administration (FDA) has not tested homeopathic remedies for safety or effectiveness. There is no guarantee that they contain consistent ingredients, or that dosage recommendations are accurate. It would be a mistake to use homeopathic remedies and dismiss valid therapies, delaying proven treatment for serious conditions.
Holistic medicine is a system of health care designed to assist individuals in harmonizing mind, body, and spirit. Some of the more popular therapies include good nutrition, physical exercise, and self-regulation techniques including meditation, biofeedback and relaxation training. While holistic treatments can be part of a good physical regimen, there is no proof of their usefulness in glaucoma therapy.
Eating and Drinking
No conclusive studies prove a connection between specific foods and glaucoma, but it is reasonable to assume that what you eat and drink and your general health have an effect on the disease.
Some studies have shown that significant caffeine intake over a short time can slightly elevate intraocular eye pressure (IOP) for one to three hours. However, other studies indicate that caffeine has no meaningful impact on IOP. To be safe, people with glaucoma are advised to limit their caffeine intake to moderate levels.
Studies have also shown that as many as 80% of people with glaucoma who consume an entire quart of water over the course of twenty minutes experience elevated IOP, as compared to only 20% of people who don’t have glaucoma. Since many commercial diet programs stress the importance of drinking at least eight glasses of water each day, to be safe, people with glaucoma are encouraged to consume water in small amounts throughout the day.
The ideal way to ensure a proper supply of essential vitamins and minerals is by eating a balanced diet. If you are concerned about your own diet, you may want to consult with your doctor about taking a mulitvitamin or multimineral nutritional supplement.
Some of the vitamins and minerals important to the eye include zinc and copper, antioxidant vitamins C, E, and A (as beta carotene), and selenium, an antioxidant mineral.
An extract of the European blueberry, bilberry is available through the mail and in some health food stores. It is most often advertised as an antioxidant eye health supplement that advocates claim can protect and strengthen the capillary walls of the eyes, and thus is especially effective in protecting against glaucoma, cataracts, and macular degeneration. There is some data indicating that bilberry may improve night vision and recovery time from glare, but there is no evidence that it is effective in the treatment or prevention of glaucoma.
There is some evidence suggesting that regular exercise can reduce eye pressure on its own, and can also have a positive impact on other glaucoma risk factors including diabetes and high blood pressure.
In a recent study, people with glaucoma who exercised regularly for three months reduced their IOPs an average of 20%. These people rode stationary bikes 4 times per week for 40 minutes. Measurable improvements in eye pressure and physical conditioning were seen at the end of three months. These beneficial effects were maintained by continuing to exercise at least three times per week; lowered IOP was lost if exercise was stopped for more than two weeks.
Benefits of Walking
In an ongoing study, glaucoma patients who walked briskly 4 times per week for 40 minutes were able to lower their IOP enough to eliminate the need for beta blockers. Final results are not available, but there is hope that glaucoma patients with extremely high IOP who maintain an exercise schedule and continue beta-blocker therapy could significantly reduce their IOP.
Regular exercise may be a useful addition to the prevention of visual loss from glaucoma, but only your eye doctor can assess the effects of exercise on your eye pressure. Some forms of glaucoma (such as closed-angle) are not responsive to the effects of exercise, and other forms of glaucoma (for example, pigmentary glaucoma) may actually develop a temporary increase in IOP after vigorous exercise. And remember -- exercise cannot replace medications or doctor visits!
Yoga and Recreational Body Inversion
The long-term effects of repeatedly assuming a head-down or inverted position on the optic nerve head (the nerve that carries visual images to the brain) have not been adequately demonstrated, but due to the potential for increased IOP, people with glaucoma should be careful about these kinds of exercises.
Glaucoma patients should let their doctors know if yoga shoulder and headstands or any other recreational body inversion exercises that result in head-down or inverted postures over extended periods of time are part of their exercise routines.
The results of studies regarding changes in IOP following relaxation and biofeedback sessions have generated some optimism in controlling selected cases of open-angle glaucoma, but further research is needed.
However, findings that reduced blood pressure and heart rate can be achieved with relaxation and biofeedback techniques show promise that non-medicinal and non-surgical techniques may be effective methods of treating and controlling open-angle glaucoma.
