title: [Effect of pricking blood at Neiyingxiang (EX-HN 9) on the intraocular pressure of patients with primary open angle glaucoma].
abstract: OBJECTIVE
  To observe the effect of pricking blood at Neiyingxiang (EX-HN 9) on the intraocular pressure of patients of primary open angle glaucoma (POAG).
  
  
  METHODS
  Ninty-six cases (166 eyes) were randomly divided into an observation group (44 cases) and a control group (52 cases). The observation group was treated with pricking blood at Neiyingxiang (EX-HN 9), and the control group was treated with 0.5% Timolol Maleate drops in eyes. The changes of patients' intraocular pressure in both groups were observed before and after treatment.
  
  
  RESULTS
  The intraocular pressure were (29.81 +/- 3.49) mmHg and (23.18 +/- 3.61) mmHg before and after treatment in the observation group, and (29.94 +/- 3.64) mmHg and (23.88 +/- 3.96) mmHg in the control group respectively, there were significant differences after treatment in the two groups (both P<0.01), while there was no significant difference in decreasing the intraocular pressure between the two groups (P>0.05).
  
  
  CONCLUSIONS
  Pricking blood at Neiyingxiang (EX-HN 9) can effectively decrease the intraocular pressure and the effect is equivalent to Timolol Maleate drops.
