ABSTRACT=<sec id="sec1"><title>Objective</title><p>Acupuncture has certain effects to improve myopia visual function, but its neural mechanism is unclear. In this study, we acupunctured at the right <italic>Taiyang</italic> acupoint of myopic patients 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.</p></sec><sec id="sec2"><title>Methods</title><p>In this study, a total of 18 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.</p></sec><sec id="sec3"><title>Results</title><p>The study found that compared with before acupuncture, the CS of both eyes in myopic patients at each spatial frequency was increased after acupuncture; compared with the resting state, the contribution of microstate C was decreased during the post-acupuncture state, and the transition probability between microstate A and microstate C was reduced; in addition, the contribution of microstate C was negatively correlated with CS at both 12 and 18 cpd.</p></sec><sec id="sec4"><title>Conclusion</title><p>The contrast sensitivity of myopic patients was improved after acupuncture at the <italic>Taiyang</italic> acupoint (20 min), which may be related to microstate C.</p></sec>
