AIM:To study of hypertensive retinopathy and brachial ankle pulse wave velocity (baPWV) correlation.METHODS:Totally 89 cases 140 eyes of patients with hypertensive retinopathy in our hospital from June 2015 to December 2016 and 30 healthy subjects (60 eyes) were selected as the research objects,and were divided into the observation group and the control group,respectively.All of the subjects were examined by direct ophthalmoscope,and the results were classified according to Keith-Wagener four classification.Application of OMRON health care (China) Co.,Ltd.production of BP-203RPE network arteriosclerosis detection device for selected objects of baPWV detection.The levels of baPWV and the results of fundus examination were compared between the two groups,and the correlation between the two methods was analyzed.RESULTS:Detection of baPWV in patients was higher as the hypertension severity increased,there was statistically significant differences between groups (P＜ 0.05).The retinopathy grade was higher,the baPWV detection value was larger,the detection value of every grade was different statistically with others (P＜0.05).CONCLUSION:Elevated blood pressure is closely related to retinopathy and accelerated pulse wave velocity,relationship between the two values is notable,brachial ankle pulse wave velocity can be used to reflect the level of hypertensive retinopathy.
