High blood pressure mainly leads to arterial vasoconstriction and arterial dysregulation in the retinal vessels. The parameters of retinal vessel analysis, in particular the assessment of the fundus hypertonicus or hypertensive retinopathy, represent additional objective parameters for the hypertensiologist to manage the treatment and evalute the success of a therapy.

Studies have shown that these microvascular parameters provide additional value in individual risk stratification, primarily in women.
