- I think for nearly all clinicians what this study has shown is that retinopathy can be quantified to identify a risk, in one sense complimenting the other risk factors that you're assessing for an individual with stroke. And this kind of helps us understand what an individual's risk is particularly going to be. And that way we can take cautions and hopefully implement more preventative strategies so that we can actually prevent the stroke from occurring. Relatively simple type of an inclusion, one additional test that you're in one sense doing anyway. You should be looking at retinopathy anyway, and now this is just considering it with what the stroke risk is going to be. So it's an important test, one that they were already doing, and now they can also consider it for the stroke risk.
