高血压视网膜病变是高血压病全身表现的一个方面,高血压患者中有眼底改变者约占64%~73%。而视网膜病变和视网膜动脉硬化分别为12%~19%[1]。血流变学和循环活化血小扳(CAP)分子标志物作为一种重要的血管内活性物质,在保持正常视网膜血管的基础张力,血流的基本供给以及微血管的循 Hypertensive retinopathy is one aspect of the systemic manifestations of hypertension. Hypertensive patients have retinal changes accounting for about 64% to 73%. The retinopathy and retinal atherosclerosis, respectively, 12% to 19% [1]. Hemodynamics and circulatory activation Small molecule pull-on (CAP) molecular markers, as an important intravascular bioactive substance, play an important role in maintaining the basic tension of normal retinal blood vessels, the basic supply of blood flow,
