Patient's skin located in the extraocular muscles projection area is routinely disinfected. A diameter of 0.20 mm and length of 25 mm needle is inserted slowly. Piercing depth is about 20mm. The electropuncture apparatus is used, each group of electrodes are distinguished with different colors of wires to generate current stimulations of current 1.0\~1.5 milliampere (mA), voltage 9 volt(V), frequency 1.5 hertz (Hz), and duration of 40 minutes.
Clinical efficacy rate (Cure, Effective and Invalid)
Clinical efficacy rate (Cure, Effective and Invalid) assessed by investigator's discretion. Efficacy rate is calculated as number of patients with Cure and effective proportional to number of all cases.
