A new research project has shown possible new techniques in relation to the pre diagnosis of potential stroke victims via retinal imaging. The Singapore based team believe that this technique way well offer affordable ways to determine those at high risk of stroke.
The use of retinal imaging allows practitioners to examine a patients blood vessels in the retina. This provides useful findings in relation to that patients blood pressure, which in turn can indicate that persons risk of stroke. Such a cheap and fast method could allow for more regular screening, without the need for invasive procedures.
The research project focused on almost 3000 patients across more than a decade, who suffered from high blood pressure, but had not previously suffered a stroke. Results of the retinal imaging research:
- Mild hypertensive retinopathy - 35% higher risk of stroke
- Moderate/severe hypertensive retinopathy - 137% higher risk of stroke
