What is Glaucoma?

A leading cause of blindness in the United States, glaucoma causes damage to the eye's optic nerve (a bundle of fibers responsible for transmitting visual information from the retina to the brain).

There are several types of glaucoma. The two most common are primary open-angle glaucoma and acute angle-closure glaucoma.

What Causes It?

Glaucoma typically occurs when fluid pressure inside the eyes slowly builds up and impairs the optic nerve.

In primary open-angle glaucoma, fluid drains from the eye too slowly, resulting in painless damage to the optic nerve and a very gradual loss of vision.

In acute angle-closure glaucoma, the iris partially blocks fluid drainage at the angle where the cornea and iris meet, causing an abrupt increase in eye pressure.

The following may increase your risk of glaucoma:

African-Americans and Mexican-Americans are more likely to develop glaucoma than Caucasians.

Symptoms of Glaucoma

Although primary open-angle glaucoma often has no symptoms, it leads to a very gradual loss of peripheral vision and - in advanced stages - tunnel vision.

Considered a medical emergency, acute angle-closure glaucoma causes sudden, severe eye pain that may be accompanied by the following:

  • Reddening of the eye
  • Stomach upset (including nausea and vomiting)
  • Sudden visual disturbances, such as blurred vision or the presence of halos around lights

Natural Approach to Glaucoma

If not properly treated, glaucoma can result in total blindness. While alternative medicine alone can't treat glaucoma, certain remedies and therapies may help manage the disease. Consider talking with your eye doctor about using the following to help prevent or control glaucoma:

1) Ginkgo Biloba

This herb may boost blood flow to the optic nerve and, in turn, have a beneficial effect on glaucoma, according to a research review published in 2001. However, the review authors note that ginkgo biloba was not found to have a direct effect on eye pressure.

2) Vitamin C

Vitamin C - an antioxidant available in supplement form and also abundant in citrus, berries, tomatoes, and other fruits and vegetables - may help reduce eye pressure and benefit people with glaucoma, a 2001 study suggests.

3) Mind-Body Stress Management

Since stress is a risk factor for acute angle-closure glaucoma, including a stress-reducing practice such as tai chiyoga, or meditation in your self-care may help protect your vision.

Treatment for Glaucoma

If you experience symptoms of acute angle-closure glaucoma, it's important to seek immediate medical attention. Treatment may include the use of medication and/or a laser procedure that promotes drainage of fluid from the eye.

Undergoing an eye exam every two years can increase your chances of detecting glaucoma in its early stages, delaying progression of the disease, and preserving your vision.

Standard treatments for glaucoma include eyedrops, oral medication, fluid-draining laser procedures, and conventional surgery that creates a new opening for fluid to leave the eye.

Using Alternative Medicine for Glaucoma

Due to the limited research, it's too soon to recommend alternative medicine for glaucoma. It's also important to note that self-treating a condition and avoiding or delaying standard care may have serious consequences. If you're considering using alternative medicine for glaucoma (or any health purpose), make sure to consult your physician first.
