Effects of Electro Acupuncture on the Function of Autonomic Nervous System in the Pupillary Diameter / 全日本鍼灸学会雑誌

ABSTRACT

The effects of electro acupuncture on autonomic nerve functions associated with the pupil were examined by measuring the diameter of the iris (D1), the maximum rate of iris constriction (VC) and the maximum rate of iris dilation (VD) before, during and after electro acupuncture.<br>An iris recorder which can be used even in the supine position was used for measuring three parameters.<br>As a result, the change with the above stimulation was reflected in a diminution of D1, presumably influencing parasympathetic nerve. Besides, VC and VD tended to increase with light reflex, presumably improving pupillary reactivity.
