Abstract: Objective To observe clinical effect of acupuncture combined with conventional visual stimulation on cerebral visual impairment(CVI) in children aged 3-10 years and influence on the pattern visual evoked potential(P-VEP). Methods A total of 60 cases of children aged 3-10 years with CVI were randomly divided into an observation group and a control group,30 cases in each group. The children in the control group received conventional visual stimulation therapy, 1 month as a course of treatment. On the basis of the control group, the children in the observation group was treated with acupuncture at Baihui(GV 20), Jingming(BL 1), Taiyang(EX-HN 5), Sibai(ST 2), etc. 3 times a week, and the treatment was given 4 weeks continuously as a course. Both groups received 3 courses of treatment. The visual acuity and P-VEP improvement were compared between the two groups before and after treatment. Results After treatment, the incubation period(P100-L) of the two groups was shorter than before treatment, and the amplitude(P100-A) was higher than before treatment(P<0.05); and the degree of above changes in the observation group was lager than the control group(P<0.05). The percentage of best corrected visual acuity of 0.6-0.8 in the observation group after treatment and follow-up 1 year after treatment was higher than before treatment(P<0.05), and was higher than the control group(P<0.05). Conclusion Acupuncture combined with conventional visual stimulation can improve the incubation period(P100-L) and amplitude(P100-A) of P-VEP in children with CVI, and improve the best corrected visual acuity in children, the clinical effect is better than the conventional visual stimulation alone.
