This clinical trial utilized acupuncture as an adjunctive treatment for glaucoma patients. It is estimated a randomized clinical trial that 50 subjects will be enrolled and observed for 12 weeks to evaluate the clinical efficacy of acupuncture, providing a reference for future clinical treatment guidelines. Participants will be randomly divided into two groups: Ophthalmic Acupoint Treatment Group and Non-ophthalmological Acupoint Control Group. Participants in the treatment group will undergo acupuncture targeting ophthalmology-related acupuncture points, aiming to elicit the 'De Qi' sensation. Conversely, the control group will receive minimum acupuncture stimulation targeting non-ophthalmic acupuncture points without the intention of achieving the 'De Qi' sensation. Both groups will undergo acupuncture therapy once a week for a total of six sessions and will be observed for twelve weeks. On each visit, intraocular pressure, blood pressure, and heart rate will be assessed. Questionnaires of Glaucoma Symptom Scale (GSS) and The Glaucoma Quality of Life-15 (GQL-15) will be performed. The data of central corneal thickness, optical coherence tomography angiography, optical coherence tomography, visual field, and best-corrected visual acuity will be collected and analyzed before acupuncture and in the 12th week.
