Laser Acupuncture for Glaucoma: Can Light Therapy Improve Eye Health?
"A Retrospective Study Explores the Potential of Laser Acupuncture to Enhance Blood Flow and Manage Open-Angle Glaucoma"
Glaucoma, often referred to as the "silent thief of sight," is a progressive eye disease that damages the optic nerve. Open-angle glaucoma, the most common form, is characterized by a gradual increase in intraocular pressure (IOP), which can lead to irreversible vision loss. While conventional treatments like eye drops, laser therapy, and surgery can help manage IOP, innovative approaches are continually being explored to improve outcomes and quality of life for those affected.
One such approach gaining attention is laser acupuncture, a modern adaptation of traditional acupuncture techniques. This therapy involves stimulating specific acupuncture points on the body using low-intensity laser light rather than needles. Proponents suggest that laser acupuncture can promote blood flow, reduce inflammation, and stimulate the body's natural healing mechanisms. As a result, researchers have begun to investigate its potential role in managing various health conditions, including glaucoma.
A recent retrospective study published in the Journal of Acupuncture and Meridian Studies delved into the effects of laser acupuncture on eye blood flow in patients with open-angle glaucoma. This article explores the study's findings, offering insights into how laser acupuncture might offer a complementary strategy for managing this challenging condition.
Glaucoma Burden and Complementary Care
Glaucoma is described as a chronic, progressive optic neuropathy requiring lifelong treatment to slow optic-nerve decline. It is also identified as the second most blinding eye disease in the world. Because treatment is extended and continuous, complementary therapies such as acupuncture are considered alongside conventional care, and previous clinical trials have reported potential reductions in intraocular pressure. A 2024 single-center randomized controlled trial protocol planned to enroll 50 participants with primary open-angle glaucoma for six weeks of weekly ophthalmic or control acupuncture.
A Half-Century of Laser Acupuncture
Laser acupuncture is described as a relatively young acupuncture modality that has been used for various conditions since the early 1970s. The reviewed history covers approximately 50 years of development and summarizes its major milestones. One account characterizes the technique as combining traditional acupuncture with the therapeutic effects of laser light, while also describing it as painless and potentially suitable for people afraid of needles.
Can Laser Acupuncture Improve Blood Flow in Glaucoma Patients?
The study, conducted by Marzio Vanzini and Michele Gallamini, involved a retrospective analysis of 98 patients diagnosed with open-angle glaucoma. These patients routinely received ultralow light-level laser (ULLLL) therapy at the Oculistica Viva eye clinic, following a specific acupuncture protocol. The researchers measured blood flow parameters before and after a six-week treatment cycle to assess the impact of laser acupuncture.
- BL1 (Jingming): Located just above the inner canthus of the eye.
- LI1 (Shangyang): Situated just behind the corner of the nail on the radial side of the index finger.
- LI4 (Hegu): Found in the middle of the 2nd metacarpal bone on the radial side.
- LI7 (Wenliu): Approximately 5 cun above the crease of the wrist on the radial side.
- LI20 (Yingxiang): In the nasolabial groove, level with the midpoint of the lateral border of the ala nasi.
- ST1 (Chengqi): Below the pupil, between the eyeball and the infraorbital ridge.
- GB1 (Tongzijiao): Slightly lateral to the outer canthus of the eye.
- TB23 (Sizhukong): In a depression at the lateral end of the eyebrow.
- EX-HN5 (Taiyang): At the temple, in a depression posterior to the midpoint between the lateral end of the eyebrow and the outer canthus of the eye.
Emerging Evidence and Ongoing Trials
A 2025 systematic review and meta-analysis reported a significant improvement in total effective rate favoring acupuncture, with an odds ratio of 3.52 and a 95% confidence interval of 2.18 to 5.68 across retinitis pigmentosa, age-related macular degeneration, and optic atrophy. Its result concerns degenerative eye diseases broadly rather than glaucoma specifically. Separately, a multicenter randomized controlled trial protocol is designed to study whether press-needle therapy improves visual function and ocular circulation in glaucoma with controlled intraocular pressure. Another cited report discusses laser acupuncture research in eye care and states that the approach may restore functionality in the central retinal artery in patients with open-angle glaucoma.
Conventional and Emerging Laser Approaches
Conventional glaucoma management options mentioned in the supplied material include eye drops, laser therapy, and surgery, all used to help manage intraocular pressure. Laser acupuncture is presented as a modern adaptation of traditional acupuncture that is being explored to improve outcomes and quality of life. Separately, research reported on September 23, 2026 compares selective laser treatment and diode laser treatment for glaucoma management over six months of patient care. The supplied sources do not provide outcome figures for that comparison or establish that laser acupuncture is superior to conventional treatment.
The Future of Glaucoma Treatment: A Holistic Approach
While the results of this retrospective study are promising, it's crucial to remember that further research is needed. However, it does suggest that laser acupuncture may offer a valuable complementary approach to managing glaucoma by improving blood flow and potentially supporting the overall health of the optic nerve. Combining such alternative therapies with mainstream medical practices could pave the way for personalized, comprehensive glaucoma care that addresses both the symptoms and underlying causes of this sight-threatening disease.
Long-Term Evidence in Normal-Tension Glaucoma
A study reported on June 1, 2026 examines the long-term efficacy and safety of acupuncture in patients with normal-tension glaucoma, a progressive optic neuropathy for which effective treatment strategies remain limited. The work follows an earlier finding that short-term, two-week acupuncture could reduce intraocular pressure. Its stated focus is whether longer-term treatment affects visual function and structural parameters, extending research beyond intraocular-pressure reduction alone. The supplied material does not provide the study's long-term results.
