Data presented as mean ± standard deviation. SG, sham group; AG, acupuncture group; EG, electroacupuncture group; V1, first assessment; V2, second assessment; V3, third assessment; V4, fourth assessment; V2-V1, the intraocular pressure difference between V2 and V1; V3–V1, the intraocular pressure difference between V3 and V1; V4–V1, the intraocular pressure difference between V4 and V1. The intervention and group effect were measured by the repeated measures analysis of variance. ∗∗p < 0.01, ∗∗∗p < 0.001 compared to SG.
