Study on the Regulatory Effect of Electroacupuncture on Intraocular Pressure in Primary Open-Angle Glaucoma Patients

INTERVENTION: Electroacupuncture Group:Electroacupuncture;Sham electroacupuncture group:Sham Electroacupuncture; CONDITION: Primary Open‐Angle Glaucoma (POAG) PRIMARY OUTCOME: Absolute IOP Reduction; SECONDARY OUTCOME: Absolute IOP;Proportion of Study Eyes with =20% IOP Reduction;Proportion of Study Eyes with IOP =18 mmHg/=15 mmHg;IOP Range (Max‐Min);IOP Standard Deviation;Visual Evoked Potential;Pattern Electroretinogram;Contrast Sensitivity;Glaucoma Symptom Scale Score;Glaucoma Quality of Life‐15 Questionnaire Score;Mean Deviation in Visual Field;Best corrected visual acuity;Optical Coherence Tomography RNFL/GCC; INCLUSION CRITERIA: Diagnosed with mild/moderate POAG in one/both eyes (Hodapp‐Parrish‐Anderson criteria) =3 months; Age =18 and =65 years, any gender; Stable use of prostaglandin analogs (PGA), carbonic anhydrase inhibitors (CAI), ß‐adrenergic blockers, a2‐adrenergic agonists, Rho kinase inhibitors (monotherapy or dual therapy) =1 month before enrollment; IOP =18 mmHg and =25 mmHg; Anterior chamber angle Shaffer grade =2; Central corneal thickness (CCT) 480‐600 µm in study eye; Voluntary informed consent and compliance with trial procedures. Note: Hodapp‐Parrish‐Anderson criteria: Mild (mean deviation (MD) > ‐6 dB), Moderate (MD ‐12 to ‐6 dB), Severe (MD < ‐12 dB).
