Does eye stroke show up on MRI?

Stroke can disrupt blood-ocular barrier

The NIH researchers discovered that a stroke can also disrupt the blood-ocular barrier and allow gadolinium to leak into the eye. Evidence of this was visible in the glowing eyes on the MRI scans of some of the stroke survivors who took part in their study.

Can you drive with one eye?
