RESUMO
OBJECTIVE: To explore the effect of Wei 's triple nine needling on visual acuity and visual field in patients with optic atrophy. METHODS: A total of 90 patients with optic atrophy were randomized into an observation group and a control group, 45 cases in each one. Treatment of Wei 's triple nine needling combined with conventional medication were adopted in the observation group, conventional medication was given in the control group. Treatment for 4 weeks was required in both groups. Before treatment and 2, 4 weeks into treatment, the visual acuity and visual field were observed, and the clinical efficacy was evaluated in both groups. RESULTS: The total effective rate was 57.8% (26/45) in the observation group, which was superior to 28.9% (13/45) in the control group (P<0.05). After 2-week and 4-week treatment, the visual acuity was improved (P<0.01), the mean defect (MD) of visual field was decreased (P<0.01), the mean sensitivity (MS) of visual field was increased in the observation group (P<0.05, P<0.01). After 2-week and 4-week treatment, the visual acuity and the MD of visual field were improved (P<0.01, P<0.05), while the difference of MS of visual field compared before treatment had no statistical significance in the control group (P>0.05). The improvement of visual acuity, MD and MS of visual field after 2-week and 4-week into treatment in the observation group were superior to those in the control group (P<0.05, P<0.01). CONCLUSION: Wei 's triple nine needling can effectively improve the visual acuity and the defect of visual field in patients with optic atrophy.
