Next time you get your vision checked, the eye doctor may be taking a look at your brain! The retina in the back of your eyes holds blood vessels that are a good indicator of overall blood vessel health inside your brain. In a recent study of women over 65, participants who had retinal vessel trouble also showed more brain vessel damage. They also scored about 15% lower in tests of memory, verbal fluency, and writing than those with healthy retinal blood vessels.
The timing of these connections—whether retinal vessel damage is the first to show up—is still being explored. But checking your eyes is so much easier than opening up your brain to check for blood vessel health!
