OBJECTIVE: To observe the effects of thumbtack needle therapy for Yangxin Shengyang (nourishing heart and elevating yang) on thickness and blood flow of macular choroid and retina in children with low myopia of heart yang insufficiency.
METHODS: A total of 120 children with low myopia of heart yang insufficiency were randomized into an observation group 1 (40 cases, 2 cases dropped out), an observation group 2 (40 cases, 2 cases dropped out) and a control group (40 cases, 4 cases dropped out). In the control group, mydriatic optometry and health education were provided. In the observation group 1, besides the interventions in the control group, the thumbtack needle therapy for Yangxin Shengyang was delivered at Dazhui (GV14), bilateral Yangbai (GB14), Cuanzhu (BL2), Taiyang (EX-HN5), Shenmen (HT7) and Xinshu (BL15). In the observation group 2, on the basis of the interventions as the control group, the thumbtack needle therapy was operated at periorbital acupoints, i.e. bilateral Yangbai (GB14), Cuanzhu (BL2) and Taiyang (EX-HN5). The intervention was given once every 3 days, for consecutive 3 months. Before and after treatment, the subfoveal choroidal thickness (SFCT), the blood flow density in the choroidal capillary layer (CC) and choroidal large vessel layer (CL), macular retinal thickness (MRT), and the blood flow density of superficial retinal capillary plexus (SCP) and deep retinal capillary plexus (DCP), spherical equivalent (SE), uncorrected distance visual acuity and eye axis length (AL) were measured in the three groups; and the traditional Chinese medicine (TCM) syndrome scores were evaluated.
RESULTS: After treatment, SFCT, MRT, and the blood flow density of CC, CL, SCP and DCP increased (P<0.05), the uncorrected distance visual acuity was improved (P<0.05), and TCM syndrome score was reduced (P<0.05) when compared with those before treatment in the observation group 1. After treatment, in the observation group 2, SFCT and the blood flow density of CL were elevated in comparison with those before treatment (P<0.05). After treatment, in the control group, SFCT, the blood flow density of CC and CL were reduced (P<0.05) and SE was progressed (P<0.05) in comparison with those before treatment. In the observation group 1, the D-values of SFCT, MRT, the blood flow density of CL and DCP, SE, the uncorrected distance visual acuity and TCM syndrome score before and after treatment were larger than those in the observation group 2 and the control group (P<0.05).
CONCLUSION: Thumbtack needle therapy for nourishing heart and elevating yang increases the macular choroidal and retinal thickness and improves microcirculation in the choroid and retina in children with low myopia of heart yang insufficiency, so as to delay the progression of refractive errors, control axial growth, and alleviate TCM syndrome to a certain extent.
