ABSTRACT=Acupuncture has certain effects to improve myopia visual function, but its neural mechanism is unclear. In this study, we acupunctured at the right Taiyang acupoint of myopia to analyze the effects of acupuncture on visual function and electroencephalographic activity, and to investigate the correlation between improvements in visual function and changes in the brain.In this study, a total of 21 myopic patients were recruited. The contrast sensitivity (CS) of the subjects was examined before and after acupuncture, and Electroencephalography (EEG) data of the entire acupuncture process were recorded.The study found that compared with before acupuncture, the CS of both eyes in myopia at each spatial frequency was increased after acupuncture; compared with the resting state, the contribution of microstate C was decreased during the postacupuncture state, and the transition probability between microstate A and microstate C was reduced; in addition, the contribution of microstate C were both negatively correlated with CS at 12cpd and 18cpd.The contrast sensitivity of myopia was improved after acupuncture at Taiyang acupoint (20 min), which may be related to microstate C.
