Electroacupuncture and Glaucoma: What Does the Research Actually Show?
A review of exploratory studies, their limitations, and the importance of established glaucoma care.

Researchers have investigated acupuncture, electroacupuncture, and other forms of electrical stimulation for possible effects on eye pressure and retinal nerve cells. These findings do not establish electroacupuncture as an effective treatment for glaucoma, and patients should continue care recommended by their ophthalmologist.
Understanding Glaucoma
Glaucoma is a group of eye diseases that can damage the optic nerve and cause permanent vision loss. Monitoring and lowering intraocular pressure (IOP) when indicated are central parts of evidence-based glaucoma management. Prescription eye drops, laser procedures, surgery, and regular ophthalmic follow-up may be recommended depending on the patient.
What Have Studies Found?
A randomized, single-blinded study published in 2020 included 45 people with glaucoma and compared manual acupuncture, electroacupuncture, and sham treatment. Investigators reported differences in short-term intraocular pressure measurements among the groups.[1]
However, a small study of short-term pressure changes does not demonstrate that acupuncture or electroacupuncture prevents optic-nerve damage, slows disease progression, or preserves sight. Replication, larger trials, and longer follow-up would be needed to evaluate meaningful clinical outcomes.
A 2022 narrative review summarized laboratory and clinical research on electrical stimulation in eye disorders, discussing potential pathways such as neurotrophic signaling, inflammatory responses, and retinal blood flow.[2] Many of these mechanisms remain experimental and may involve stimulation methods different from electroacupuncture.
A 2025 systematic review and meta-analysis of acupuncture for degenerative eye diseases reported that pooled results did not demonstrate statistically significant overall improvements in visual acuity or intraocular pressure. The authors called for stronger research.[3] This broader evidence limits what can responsibly be concluded from individual positive studies.
What Is Electroacupuncture?
Electroacupuncture is a form of acupuncture in which fine needles are placed at selected points and connected to a device that delivers adjustable electrical pulses. It differs from electrical stimulation delivered directly to or around the eye. Results from one technique cannot automatically be applied to another.
What Should Patients Know?
For now, electroacupuncture is not a proven substitute for glaucoma medications, laser treatment, surgery, or specialist monitoring. No evidence reviewed here establishes that it reverses optic-nerve damage or prevents glaucoma-related blindness.
Patients interested in acupuncture for other concerns should tell their ophthalmologist and acupuncturist about their diagnoses, devices, medications, and treatment plans. Decisions about any complementary care should not delay proven glaucoma treatment.
Looking Ahead
Investigating the nervous system's responses to electrical stimulation is a legitimate scientific question. Determining clinical usefulness requires robust human studies measuring sustained eye-pressure control, optic-nerve outcomes, visual fields, safety, and vision-related quality of life.
