Differential diagnosis | hypertensive retinopathy |
Salus's sign is a clinical sign in which deflection of retinal venules can be seen on fundoscopy occurring in patients with hypertensive retinopathy.[1] Arteriosclerosis causes shortening or lengthening of arterioles, which causes venules to be moved at points where arterioles and venules cross over. This is seen at right-angle crossing points, where the venule crosses the arteriole in a horseshoe shape.[2]
The sign is named after Robert Salus.[3]
