TIA (Mini-Stroke): When your Vision Flickers and Fades

Let’s say you’re doing something totally normal like eating lunch, going to work, or taking a walk, and all of a sudden, part of your vision disappears. It might look like a blank spot, or a blurry spot. Then, a few minutes later your vision is back to normal.

This could be something called a TIA, or Transient Ischemic Attack which is a mini-stroke that sometimes affects how you see.
 

What Is It?

A TIA is a short, temporary block in blood flow to the brain. It’s like a warning light turning on in your body. When this happens in the part of the brain that controls vision, it can cause sudden, short-lived vision loss in one or both eyes.
 

What Does It Feel Like?

• Vision suddenly goes blurry or blank.
• You might not be able to see on one side.
• It usually doesn’t hurt.
• It lasts a few minutes to an hour, then clears up.

Why Does It Happen?

The blood vessels in your brain act like highways. A TIA is when there’s a quick “traffic jam” that blocks blood from getting through. After a few minutes, the traffic clears and everything goes back to normal. However, it’s a sign that a bigger problem could be coming.
 

Should I Be Worried?

Yes. Even though the vision loss is temporary, a TIA is a red flag. It could mean you’re at risk for a real stroke. TIAs are more common in older adults, but if it ever happens to you or someone you’re with, don’t wait. Call a doctor or go to the ER right away.
