Clinical Trial Summary

The purpose of the study is to testify the efficacy of treating oculomotor nerve palsy with ocular electroacupuncture or ocular acupuncture, and to compare the efficacy between these two interventions.

Description:

The purpose of the study is to testify whether ocular electroacupuncture or ocular acupuncture is effective for oculomotor nerve palsy (ONP), through treating ONP patient for 6 weeks, using self-invented acupoints according to anatomy of extraocular muscles innervated by oculomotor nerve, and using sham acupuncture as controlled group, and try to provide clinical evidence for promoting these new techniques.

Intervention

Other:
• ocular electroacupuncture
During intervention period, patients will continue to keep medications for primary condition. 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.
• ocular acupuncture
During intervention period, patients will continue to keep medications for primary condition. 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 duration of intervention is 40 minutes.
• sham acupuncture
During intervention period, patients will continue to keep medications for primary condition. Patient's skin located in the extraocular muscles projection area is routinely disinfected. A diameter of 0.20 mm and length of 25 mm sham needle set is stick onto insertion area without piercing into the skin. The duration of intervention is 40 minutes.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Baseline in Ocular motor nerve function subscale at 6 Weeks	The patient will receive grading of eyelid lifting, eyeball inward, upward and downward moving ability by investigator. A total score will be summed up.The changes from baseline will be recorded.	6 week
Secondary	Angle of diplopia deviation	Patients will receive computerized diplopia test with the guidance from an investigator. The data will be generated by the software automatically.	6 week
Secondary	Eyeball movement distance	The distances of eyeball movement in inward, upward and downward direction and height between eyelids will be measured. The differences between affected and healthy eye will be calculated.	6 week
Secondary	The quality of life questionnaire for ocular motor nerve palsy	The patients will finish a questionnaire to evaluate their physical and psychological status during this trial.	6 week
