Glaucoma is a group of diseases that can cause vision loss by damaging the optic nerve. This damage can sometimes be caused by an increase of pressure inside of the eye (intraocular pressure). However, many people with glaucoma have normal or low intraocular pressure. Although it is not yet fully understood how each type of glaucoma damages the optic nerve, one common feature to all types of glaucoma is the lack of blood flow to the retina and optic nerve. This can eventually cause retinal nerve cell death and loss of vision. This is where acupuncture can help.

Acupuncture and Glaucoma | The Research

Decreasing Intraocular Pressure

Researchers in Germany studied the effect of acupuncture on 18 patients diagnosed with glaucoma and high intraocular pressure. Measurements of the pressure were taken 15 minutes before, 15 minutes after, and 24 hours after treatment with acupuncture. Patients showed an average decrease of 2.5 mm Hg in their intraocular pressure with no adverse effects.¹

Japanese researchers also reported intraocular pressure “significantly improved” after receiving acupuncture twice a week for five weeks. They also noted that the pressure “tended to be lower weekly” as treatment continued.²

Research at the Ophthalmology Department of Ji County TCM Hospital in Tianjin China also reported a decrease in intraocular pressure measured several times for 24 hours after acupuncture treatment.³

Increasing Circulation to the Eyes

It has been known for many years now that glaucoma is associated with a decreased blood flow velocity in blood vessels of the eye (the retrobulbar vessels). This impaired circulation contributes to the damage of the optic nerve. Therefore, more drugs and interventions are being researched to help improve this problem of blood flow in the eyes for glaucoma patients.

A Japanese study utilizing acupuncture for glaucoma patients displayed a positive effect on increasing retrobulbar circulation. Their results also showed a decrease in intraocular pressure. The study concluded that we should consider utilizing acupuncture as an adjunct therapy for glaucoma patients.4

Improvement of Visual Acuity

A study out of Japan also showed acupuncture’s effect on improving visual acuity in patients suffering from glaucoma. Acupuncture was given two times a week for five weeks and the researchers noted that, “uncorrected visual acuity was significantly improved at three weeks, four weeks, and five weeks, and best corrected visual acuity was significantly improved at five weeks.”²

Conclusion

Glaucoma can be a very serious disease that can lead to significant vision loss and blindness. It’s important to visit your ophthalmologist for a complete eye examination every couple of years unless you have any of the following:

• family history of glaucoma
• significant nearsightedness
• diabetes
• corneal disease
• smoke a pack or more of cigarettes a day
• are African-American (three times more likely to develop open angle glaucoma)

If you have any of those risk factors, you should have a complete eye exam every year.

Acupuncture should be considered as an adjunct therapy to help preserve the health of the optic nerve. It’s effects on improving circulation to the eyes, decreasing intraocular pressure, and improving visual acuity, make it a worthwhile tool for many people suffering from glaucoma. When combined with a proper Chinese medicine herbal formula and other supplements designed to improve the overall health of the body, the treatment will be even more effective. It is important to remember, that the health of the eyes relies on the health of the entire body.
