Mild hypertensive retinopathy shows significant angiographic differences to the severe form. Changes in the fundus, visible using ophthalmoscopes, seem to indicate prognosis in patients with arterial hypertension.
As such, researchers proposed several schemes to grade the alterations. For example, the Neubauer scheme differentiates between fundus hypertonicus (stages I-II) and hypertensive retinopathy (stages III-IV). More recently, fluorescein angiography facilitated assessment of changes to the perivoveal microcirculation arising from hypertension.
Therefore, researchers from the University Eye Hospital Basel, Switzerland and centres in Germany, aimed to determine whether the angiographic results can be stratified in a similar manner to the ophthalmoscopic classification.
