A research team in Taiwan studying acupuncture for glaucoma, has shown that it can be used to lower intraocular pressure. In their randomised, three-arm trial, 45 glaucoma patients were randomised to receive either acupuncture, sham acupuncture, or electroacupuncture twice a week for two weeks.
The reduction in intraocular pressure from immediately before treatment to one hour after treatment, was significantly greater in the acupuncture and electroacupuncture groups, compared with the sham group. This held true for all four treatment sessions and in both eyes.
