老年人患高血压,常伴有全身动脉硬化,眼底检查往往有助于动脉硬化的诊断。因为视网膜中央动脉属小动脉,它能代表全身小动脉特别是脑和肾的动脉血管的情况。关于高血压引起的视网膜动脉硬化,至今国内外文献报道不多。本文就高血压性视网膜动脉硬化的发病率、病因、病理、眼底改变、严重的合并症、治疗原则等方面进行了初步探讨。 1.发病率老年人有动脉老化现象,如伴有高血压,易致视网膜动脉硬化。60岁以上老年人患高血压,眼底检查有视网膜动脉硬化改变者占89％(张汉丞氏)而眼底改变又与血压升高程度,特别是舒张压高关系较大。而肾脏有损害者,眼底改变也严重。
High blood pressure in the elderly, often accompanied by systemic arteriosclerosis, fundus examination often contribute to the diagnosis of atherosclerosis. Because of the small artery of the central retinal artery, it represents the arterioles of the systemic arterioles, especially the brain and kidney. About retinal arteriosclerosis caused by hypertension, so far little literature reported at home and abroad. In this paper, the incidence of hypertensive retinal arteriosclerosis, etiology, pathology, fundus changes, severe complications, treatment principles were discussed. 1. The incidence of arterial aging in elderly phenomena, such as associated with hypertension, retinal atherosclerosis easily caused. People over the age of 60 suffering from hypertension, fundus examination of retinal arteriosclerosis were accounted for 89% (Zhang Han Shing) and fundus changes and blood pressure levels, especially diastolic blood pressure higher. The kidney damage, fundus changes are also serious.
