Study Summary

The goal of this clinical trial is to test the therapeutic effect of acupuncture at the Jingming and the Qiuhou acupoints on the visual acuity and visual field in patients with primary open-angle glaucoma.

Participants will get acupuncture or Wangbuliu Xingzi Paste (sham acupuncture) on both sides of the Jingming and the Qiuhou, once a week, once for 20 minutes, for 24 weeks.

Researchers will compare acupuncture group and sham acupuncture group to see if the visual acuity, visual field, intraocular pressure, optic nerve fiber layer thickness, serum homocysteine concentration, and scores on the WHOQOL-REF (Taiwan version) scale would be improved.

Study Description

Glaucoma is a syndrome. The long-term increase in intraocular pressure eventually leads to visual field defect and blindness. Lowering the intraocular pressure in patients with glaucoma is considered to be the most effective way to treat glaucoma. Many studies believe that both blood circulation around the eyes and increased intraocular pressure play a critical role in glaucoma. Some studies have shown that acupuncture can adjust intraocular pressure and improve optic nerve activity, as well as increase blood flow of the eye fundus. Jingming (BL1) can communicate yin and yang, nourish and improve eyesight, and Qiuhou (EX-HN7) can promote qi and blood circulation, and improve vision. The results of our previous research found that acupuncture or electroacupuncture can reduce the intraocular pressure in patients with glaucoma. Therefore, the purpose of this study is to assess the therapeutic effect of acupuncture at the Jingming and the Qiuhou acupoints on the visual acuity and visual field in patients with primary open-angle glaucoma. This study designed a randomized, single-blind, controlled clinical trial. A total of 40 patients with primary open-angle glaucoma were randomly divided into two groups equally as follows: 1) Sham acupuncture group: Only use Wangbuliu Xingzi Paste on the skin on the acupoints on both sides of the Jingming and the Qiuhou, once a week, once for 20 minutes, for 24 weeks; 2) Acupuncture group: The method is the same as the sham acupuncture group, but the stainless steel needles are used to insert into the two points of Jingming and the Qiuhou, and der-qi, once a week, once for 20 minutes, for 24 consecutive weeks. The main assessment is visual acuity and visual field; the secondary assessment includes intraocular pressure, optic nerve fiber layer thickness, serum homocysteine concentration, and changes in scores on the WHOQOL-REF (Taiwan version) scale.

It is expected that acupuncture intervention can improve the visual acuity and visual field in patients with glaucoma.
