Randomized Controlled Trial Clinical TrialQuantitative analysis of retinal vascular changes in essential and renovascular hypertension.
To describe a quantitative analysis method for retinal vascular changes and to study retinal vascular changes in patients with mild essential or renovascular hypertension in relation to 24-h ambulatory blood pressure monitoring. ⋯ Our quantitative retinal vascular analysis method detected an increased vascular diameter in both essential and renovascular hypertensives, which was related to night-time blood pressure and, in particular, to an attenuated nocturnal blood pressure decline. Vascular rarefaction in essential hypertension was not related to blood pressure and could influence the pathogenesis of essential hypertension.
