目的：探讨青光安颗粒剂对慢性高眼压兔眼眼内组织的保护作用。方法：采用光镜和电镜观察方法，通过与丹参组、模型组、正常对照组的比较，观察青光安颗粒剂对慢性高眼压兔眼角膜、巩膜静脉窦、虹膜睫状体、视网膜组织的影响。结果：模型组兔眼角膜、巩膜静脉窦有轻度异常改变，虹膜睫状体和视网膜组织病理改变明显；丹参组兔眼眼内各组织结构相对保存较好；而青光安颗粒剂组兔眼眼内各组织比丹参组保存得更好，其病理改变不明显。结论：青光安颗粒剂对慢性高眼压兔眼眼内组织结构具有保护作用
Objective: To investigate the protective effect of Qingguang Granules on intraocular tissue of chronic ocular hypertension rabbit eyes. Methods: Using light and electron microscopy methods, through the comparison with Salvia miltiorrhiza, model group and normal control group, we observed the effects of QingGuangAng granule on chronic corneal ocular hypertension, scleral sinus, iris ciliary body, retinal tissue Impact. Results: The cornea and scleral sinus of rabbits in model group had mild abnormal changes, and the histopathological changes in iris, ciliary body and retina were obvious. The tissues in the eyes of Salvia miltiorrhiza group were relatively well conserved, while those of Qingguangan granule group Eye tissue within the organization than Salvia better preserved, the pathological changes were not obvious. Conclusion: Qingguang granules can protect the intraocular tissue of chronic ocular hypertension
