Effect of Acupuncture on Intraocular Pressure in Glaucoma Patients: A Single-Blinded, Randomized, Controlled Trial

Abstract EN

Glaucoma is characterized by the degeneration of retinal ganglion cells that cause progressive optic neuropathy, finally resulting in changes to the optic nerve head.

Lowering intraocular pressure (IOP) is the only method proven for treating glaucoma.

Several studies have discovered that acupuncture can reduce IOP and also increase ocular perfusion and ocular blood flow.

Therefore, the present study investigated the effect of acupuncture on IOP in glaucoma patients.

We conducted a single-blinded, randomized, controlled trial involving 45 glaucoma patients.

The results indicated that the difference between the IOP 60 min after the intervention and IOP immediately before the intervention was greater in the acupuncture group (AG) and electroacupuncture group (EG) than in the sham group (SG) for all four of the interventions performed and in both eyes (all p<0.05).

The IOP difference between immediately before the first intervention and after finishing the final intervention was also greater in the AG and EG than in the SG in both eyes (all p<0.05).

In conclusion, IOP was reduced at 60 min after acupuncture or electroacupuncture was performed at BL1 and EX-HN7.

Additionally, IOP was reduced after finishing four acupuncture or electroacupuncture sessions.

Therefore, our results suggest that acupuncture and electroacupuncture are beneficial for lowering IOP in glaucoma patients.

This trial is registered with NCT04157530.
