Summary

To determine if electroacupuncture acts as an dry eye treatment rather than a placebo, and identify if benefits are linked to corneal subbasal nerve changes and neuroimmunomodulatory indicators.

Conditions

  • Dry Eye

Interventions

DEVICE

Verum Electroacupuncture

Acupoints: Cuanzhu (BL2), Taiyang (EX-HN5), Sibai (ST1), Sizhukong (TE23), Baihui (GV20), Fengchi (GB20), Hegu (LI4), Zusanli (ST36), Guangming (GB23), Sanyinjiao (SP6), and Taichong (LR3). All acupoints will be taken bilaterally, except Baihui (GV20). The subject is placed in the supine position with eyes close. After routine sterilization, the sterile polyethylene cylindrical needle pad will be adhered to the acupoints. Then, the sterile acupuncture needles (0.25 mm×0.40 mm, Hwato brand, China.) will be inserted into the skin through the needle pad. Twirling and lifting-thrusting manipulations will be performed on the acupoints until Deqi is reported by the subject. Two pairs of electrodes will be connected at the needle handles on BL2 and EX-HN5 with a 2 Hz, continuous-wave electro-stimulation provided by the electroacupuncture apparatus (SDZ-Ⅲ type, Hwato brand, China). The pulse amplitude is about 1-2 mA.

DEVICE

Sham Electroacupuncture

Sham acupoints: SA1(1 cm above BL2), SA2 (1 cm above SJ23)，SA3 (1 cm above EX-HN5), SA4 (1 cm lateral to ST2), SA5 (the midpoint of the line between GV20 and right EX-HN1), SA6 (the midpoint of the line between GB20 and SJ16), SA7 (1 cm lateral to LI4), SA8 (the midpoint of the line between ST36 and GB34), SA9 (the midpoint of the line between GB37 and BL58), SA10 (1 cm backward to SP6), SA11 (the midpoint of the line between LR3 and SP4). After routine sterilization, placebo needles will be used (Streitberger, Asia-med GmbH). The tingling sensation produced when the Streitberger needle is fixed on the skin causes the subject to believe that the needle is piercing the skin, simulating a skin puncture. The electric stimulator is applied to bilateral SA1 and SA3 with no current output. The exterior appearance, indicator light, prompt tone of the sham device, and stimulation parameters are all indistinguishable from the normal one.
