Abstract/OtherAbstract:
It is known that in advanced hypertensive retinopathy, which changes advanced hypertensive retinopathy (Grade III or IV), there is a strong relation between retinal microvascular lesions and cardiac and macrovascular markers of target organ damage (TOD). The prevalence of grade II hypertensive retinopathy and its relationship to cardiovascular risk factors remain controversial. The subjects, a total of 437 hypertensive patients, were divided into three groups according to modified Keith, Wagener, and Barker (KWB) classification by two ophthalmologists: Grade 0 with normal retinal change (N = 169, 38.7%), Grade I with arteriolar narrowing (N = 215, 49.1%), Grade II with arteriovenous crossings (N = 49, 11.2%). The prevalence of Grade I and Grade II hypertensive retinopathy was significantly higher than that of advanced hypertensive retinopathy. The grade of hypertensive retinopathy was related to age, duration of hypertension, coronary artery disease (CAD), and left ventricular hypertrophy (LVH). The prevalence of LVH and CAD in Grade II was significantly higher than in Grade I and Grade 0. The hypertensive retinopathy Grade II was significantly correlated with LVH (odds ratio (OR) 2.3, 95% confidence interval (CI) 1.21-4.44, p < 0.05) and CAD (OR 4.2, 95% CI 1.97-8.95, p-<-0.001). Grade I and Grade II hypertensive retinopathy are frequently observed in hypertensive patients compared to Grade III and IV patients. We concluded that Grade II hypertensive retinopathy is closely related to CAD and should therefore not be ignored.
