This paper introduces the clinical experience of Lu’s acupuncture and moxibustion in the treatment of diplopia. It is believed that the etiology and pathogenesis of diplopia are external pathogenic factors blocking collaterals, deficiency of qi and blood, deficiency of the liver and kidney, and stagnation of qi and blood stasis. During the treatment, we should pay attention to treatment based on syndrome differentiation and follow the three principles of “local acupoints to dredge local meridian qi”, “distal acupoints to regulate whole body qi and blood” and “selecting corresponding Back-Shu acupoints to regulate the function of zang-fu organs”.
