What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Plum-blossom NeedleOther

    Also called Double head dermal needles (HWATO, China)

    • acupoint selection: Zhengguang 1, Zhengguang 2, GB20, GV14, LI4.
    • plum-blossom needle manipulation methods: After the skin has been wiped with 75 % alcohol, plum-blossom needles will be tapped perpendicularly on the skin at the selected acupoints with wrist force and then lifted immediately. Each point will be tapped repeatedly for 20 to 50 times and both sides of cervical vertebra and temporal region, Suprao-infraorbital margin will be tapped repeatedly. Acupuncturists should tap the points gently to make patients feel only a little pain and stop when the skin gets flushed but is not bleeding.
  • Tropicamide Eye DropsDrug

    Also called 6ml:30mg(0.5%)(FREDA, China)

    Instill one drop in both eyes every night before bed.
