[Effect of pricking blood at Neiyingxiang (EX-HN 9) on the intraocular pressure of patients with primary open angle glaucoma].

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 P0.01),while there was no significant difference in decreasing the intraocular pressure between the two groups (P0.05). Conclusion Pricking blood at Neiyingxiang (EX-HN 9) can effectively decrease the intraocular pressure and the effect is equivalent to Timolol Maleate drops.
